Re: [PHP] how old is this version of PHP?
Far too much is made of BC breaks between PHP versions. Well-behaved code should still be working a decade later. The catch is that well behaved gets tighter each release. For example: $foo = hello; $bar = world; print $foo[$bar]; In PHP 5.3 and earlier, $bar is a string which makes no sense as an index of a string. It needs to be an int. PHP therefore casts that to an int, gets 0, and you get h. In PHP 5.4, that was acknowledged as a bug (which it always was), and now triggers a Warning. Because, really, it always was a bug but just failed silently before. Now it tells you so you can fix it. It looks like a BC break, though, because I get an error I didn't used to. Other things are, eg, removing register_globals and magic_quotes, which have been deprecated for about 12 years and if you were still using them now then your code should break. :-) They're a security hole.

Which is best depends on who you ask. :-) I would argue that there's 3 good approaches, both of which are viable: 1) Define your form abstractly via an API, and have the API detect the presence of POST request and then process the form after it's built. That means you do submit back to the same URL. (Drupal 7 and earlier do this.) 2) Put 2 separate request handlers / controllers at the same path, one for GET and one for POST. So you submit back to the same URL but an entirely different piece of code responds to it. (This requires a good routing system that can differentiate between GET and POST.) 3) Every form is defined as its own object somewhere with a unique ID. All forms post to the same URL but include the form ID. Code at that URL looks up the form object by ID and maps the submitted data to it to know what to do with it. Note that in all 3 cases you're defining a form via an API of some kind. You are not writing form tags yourself. Don't do that. Ever. I promise you that you will have a security hole or six if you do. Use a good form handling API for building forms. That's what good Real projects do. There are a lot out there. Most fullstack frameworks or CMSes have one built in (I know Drupal and Code Ignighter do, although they're quite different), and there are reasonably stand-alone components available in both Symfony2 Components and Zend Framework.

Without giving me complicated examples, just give me one simple example that illustrates the advantage of using an interface over writing a new Class where you flesh-out whatever methods you want. After all, an interface requires the same thing, does it not? As such, I just don't see the advantage interfaces bring. Cheers, tedd Practical example, PSR-3: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md Say you're writing a stand-alone library, maybe a Twitter-connecting library. You want to be able to log stuff, but don't want to have to deal with opening log files yourself. You also want to allow your library to be used by people running Symfony, Code Igniter, Drupal, Zend Framework, or PHPBB, all of which have their own logging systems in place that may talk to syslog, a database, files on disk, or whatever. People using those frameworks don't want your library spewing log files all over their file system. Instead, you simply support the PSR-3 logging interface. You accept an object that implements that interface in your constructor, and then write to it. What happens on the other side? Who gives a damn! For your own testing, you can write a simple class that implements that interface and dumps log messages to disk. When someone uses your library with Symfony, they just pass in a Monolog object (the logging system used by Symfony), and your code is now logging errors to whatever they have Monolog configured to do. When someone uses your library with Drupal, they just pass in the Drupal Watchog logger object (which is being rewritten to use PSR-3 as we speak), and now your library is logging errors to Drupal's logging system (which could be syslog or a DB table, depending on how the user has their site configured). And you don't give a damn about any of that. All you care about is that you support any object that matches this interface. What that object does with the messages you send it, and where that object came from, you don't have to give a crap about. Now take that same concept and apply it at a smaller scale, within your own project. Swap out your database-based cache system for a memcache-based one. Your code doesn't change, because it's writing to an interface, not to the database. Swap out your data store with one that is used just for testing. Etc. That's what interfaces give you. Loose coupling, and the ability to divide-and-conquer... and even let someone else solve problems for you. :-) --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You have to declare the arrays as global inside your function.

I don't seem to have the DateTime object. We are running 5.1.6 and
that was added in 5.2.0. We are getting the Date module from an
external extension. I'll have to see about upgrading.
I've upgraded to 5.3.3, got rid of the external Date extension and

[PHP] ?=$var?
Continuing in my effort to port an app from PHP version 5.1.6 to 5.3.3, the app uses this construct all over the place when building links: ?=$var? I never could find any documentation for this, but I assumed it was some conditional thing - use $var if it's defined, otherwise use nothing. In 5.1.6 it seems to do just that. But in 5.3.3 I'm not getting the value of $var even when it is defined. Has this construct been deprecated? Is there now some other way to achieve this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

One of the 'standards' adopted when working world wide is to ensure what is
stored IN the database is always UTC based. So you can always compare times
on the same consistent base. The only time you need the offset is to display
a local time, and that is either the time local to the server, or the time
local to the client.
The 'default' timezone is not necessarily the right one in either case ;)
I misspoke - the data in the db is in UTC. This is used to covert the
time of day on the server to the user's local timezone.

You are aware that the code you used is really bad practice, right? You're
basically hiding the error no default timezone set by getting the default
timezone, which returns an error; surpressing that error, providing the
date_default_timezone_set function with the default value of
date_default_timezone_get if none is defined (which there should!!), being
UTC.
So in short, you're saying set the default timezone to the default timezone
if no timezone is set, which I know there is not. That's very hard to
understand for future programmers reading your code. Why not just set
date_default_timezone_set('UTC'). It's clear, resolves the warning and
works perfectly, instead of relying on vague defaults somewhere, in the hope
they're set right.
On a sidenote; the reason why your original fix did not work:
$deftz = date.timezone;
Is because date.timezone is an ini setting. Not valid PHP code. And the
error actually tells you you need to SET date.timezone, not set a variable
TO the ini setting. In other words, you wanted date.timezone = UTC instead
of $tz = date.timezone (which makes no sense anyway)
But UCT is not the timezone. When this app runs in New Mexico (where I
am) it's Mountain time. When it runs in NY it's Eastern. When it runs
in Tokyo it's JST, etc. The user has the option of setting the
timezone all times are displayed in. They can select any timezone
regardless of where they are. The app displays the last update time in
the user selected TZ. So I have to convert the time I get from the
server to that.

Well, if you're getting the Date class from a custom extension, then we
can't help you. Simply because we have no clue what the extension's code is.
Also, please ask your host to upgrade, 5.1.6 is hopelessly outdated (and
unsupported!). The current version is 5.4 with 5.5 coming out very very
soon.
The extension is this:
http://pear.php.net/package/Date/docs/latest/Date/Date.html - but that
is also a very old version. I am working on getting the upgrade done.

On 03/14/2013 01:21 PM, Bob Weinand wrote: Sharing active memory between processes goes against the shared nothing design of PHP. The lack of the feature you're describing is itself a feature. :-) If you had real shared memory, then you're now writing a multi-threaded app. Even if you aren't using threads per se it's the same level of potential for spooky action at a distance. If your problem space really requires that (and there certainly are those that do), Java or NodeJs will suit you better because those are built specifically for a persistent-server model, rather than PHP's shared-nothing design. However, in practice most PHP/web applications don't need that, because HTTP is a stateless request/response system. Shared-nothing more closely models what the actual environment is doing, and can still be very performant as long as you don't do anything naive. If you're doing something stateful like Web Sockets, then you can run PHP as a cli application that is its own persistent server rather than as an Apache add-on. For that, look at Ratchet: http://socketo.me/ --Larry Garfield If PHP should be so restrictive against sharing, why are there extensions like memcached, ...? Someone must have missed this possibility to share rapidly... If I need something like websockets, I use the pthreads extension: perfectly suited for stateful applications. For example: I want to have the database in memory (no, no mysql Memory-tables; this is too slow...) and only do the updates into the database for faster access when most contents are read-only. What are these good reasons against such a feature except it violates the shares-nothing superlative of PHP. (Even if this feature would exist, you can still write PHP without sharing) Bo Weinand Memcache is out of process. There are possible race conditions there, but FAR fewer and FAR more contained than true multi-threaded environments. This list has debated the merits of shared-nothing many times before; it was a deliberate design decision in the interest of simplifying development for the overwhelming majority of users. If your app is so performance sensitive that a memcache lookup is going to bring it to its knees, then either you're misusing PHP or you're better off using something other than PHP. (PHP is not the tool for every use case.) In any event, adding true shared memory to PHP would be nearly impossible without completely redesigning the way it interacts with web servers. The alternative is to write your own PHP CLI application that connects to sockets itself and runs as a daemon (possibly using the pthreads extention as you mention), and cut apache/nginx out of the picture entirely. If your use case calls for that, knock yourself out. But the good reasons against adding such a feature is that it would require rewriting everything and rearchitecting the entire Apache SAPI, which is not happening any time soon. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

function something_else_long() {
}
That helps both readability and testability.
Also, on your original boolean question, note that negation is
distributive. That is:
!($a $b $c)
is the same as:
!$a || !$b || $!c
Which means that if your checks are all equality checks, as in your
case, you can simply do:
if ($a != 'a' || $b != 'b' || $c = 'c') {
}
Which may be easier to read. If those checks are not trivial then
there's also a micro-performance benefit there, as the first statement
that evaluates to true will cause the whole thing to return true, so the
second and third options don't need to be evaluated.

Re: [PHP] static Logging class?
Make a real classed object that you pass to various objects that need it. Otherwise you make your life way harder for unit testing. Don't have a class that self-enforces that it's a singleton. That way lies pain. In particular, I recommend using or writing a class based on the PSR-3 recommendation: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md There's even stock code for the interface and some useful base classes available: https://packagist.org/packages/psr/log And for added fun, there are already publicly available open source libraries that implement PSR-3 that you can just drop in and use, such as: https://packagist.org/packages/monolog/monolog (If that's too heavy for you, writing your own PSR-3 compatible logger is dead-simple.) I'm sure you're about to say zOMG this is just a hobby project, I don't need something that fancy and all injected and shit!

It also means you can scale up by just adding more servers, because you don't need to deal with oh, now the memory isn't shared, so now what do I do? Each PHP process could be in its own CPU core, CPU, server, or server cluster, and the code doesn't change in the slightest.

Yes, the mysql extension is deprecated, but what's wrong with mysqli?
mysqli has the advantage that you don't need to keep a database handle
floating around, but you can just use mysqli_query everywhere.
When having multiple files and classes, it's terrible to pass $db to
each function/class, and I hate to use the global keyword.
just use while($record = $result-fetch_array()) instead of
foreach($result as $record)
And you mention ext/mysql is slow, well don't know about that, but PDO
is a bit slower than mysqli atleast.
I quote from [1]:
For inserts, there was no significant difference between MySQLi and
PDO (prepared statements or not). For selects, MySQLi was about 2.5%
faster for non-prepared statements and about 6.7% faster for prepared
statements.

[1] http://jnrbsn.com/2010/06/mysqli-vs-pdo-benchmarks
Nothing is wrong with mysqli per se. It's up to date and secure, and
certainly better than ext/mysql. I recommend PDO over mysqli because:
1) PHP-engine-level global state (ie, not specifying a connection) is
the source of most (although not quite all) evil. Really, that way lies
pain once you get into anything reasonably complicated and want to be
able to test it properly.
2) PDO is installed by default on virtually every PHP system in the
world. ext/mysqli has never been part of the default build of PHP, and
many to most web hosts don't have it installed.
3) mysqli's API is a bizarre hybrid of procedural and OO that confuses
the heck out of me. PDO's is far from perfect, but is more consistent
and cleanly OO from the get-go.
I skipped mysqli entirely and went straight to PDO when it became available.

Dave,
Foreach is an iterator over an array. Your $row is a pointer to a db result
set. If you were to pass the $row result set to the foreach as an array,
you'd get what you think you should
Www.php.net/foreach
Thanks Bastien.
Heres what I started with:
$result = mysql_query(SELECT * FROM items);
$row = mysql_fetch_array($result);
foreach($row as $rows){
$row = 0;
if($row == 0){
echo $rows;
} else{
echo Too expensive I'm going home LOL;
}
}
Here's what I ended up with after you gave me the advise:
$result = mysql_query(SELECT * FROM items);
$rows = array();
while($row = mysql_fetch_array($result))
$rows[] = $row;
foreach($rows as $row){
$product = $row['product'];
$price = $row['price'];
echo $product ;
echo $price ;
$justright = 0;
$toohigh = 5; //I was going to use this to check if the price was too high

Well, i would then do something like this from within the included

PluginLoader::getInstance()-registerPlugin(new PluginOne());

Then you get an instance of the plugin:
$plugin = PluginLoader::getInstance()-factory('PluginOne');
Tho, even then I don't see what the PluginLoader is adding to the party.
Well, i'm making the classes up as i type. I don't actually have a
PluginLoader yet. Or rather, i'm just beginning to make it right now.
What it's doing is very simple. Read through the directory of the
plugins and load every single plugin it finds in memory. Then every
plugin registers the mime types it can handle. That information is
stored in the PluginLoader upon which some other place can call:
PluginLoader::pluginForMime(text/html). Though i still have to take
a good look at that.
But you're right, i can use the factory pattern here.
Ahh, I see. Personally I'd go with the following (pseudocode)...
Inside the PluginLoader constructor (or other method)
foreach (plugindir)
require plugindir/plugindir.php
$plugindir::init($this)
The static init() method calls PluginLoader::registerPlugin('mime/type',
'PluginClassName'). Then pluginForMime does a lookup for the mime type and
returns an object of the corresponding type. That way a single plugin can
support multiple mime types.

You should never be calling require() yourself. Just follow the PSR-0
naming standard and use an autoloader, then you don't have to even think
about it. There are many existing autoloaders you can use, including
Composer's, Symfony2's, and probably Zend has one as well.
Also, the key question is how you'll be mapping your situation to the
plugin you need. If it's fairly hard-coded (i.e., mime type of foo =
class Bar), then just use a simple dependency injection container like
Pimple. If it's more complex and situational, then yes a factory is the
easiest approach.

[PHP] Variables are empty only in fwrite
Hello, when I pass a variable whose value originally came from $_GET or $_REQUEST to fwrite, fwrite behaves as if it was passed an empty string. Note that the file is successfully opened and written to by the script, but the variable that originally came from $_GET does not have its value interpolated in the text file, even though it does get interpolated in the echo(). Code ? $meh = $_GET[q]; $writeline = : . $meh . : . strlen($meh) . PHP_EOL; echo ( $writeline ); $fp = fopen(/tmp/wtf.log,w+); fwrite($fp, $writeline ); fclose($fp); var_dump($writeline); ? Request /search.php?q=meh123 Response --- ( expected ) :meh123:6 string(10) :meh123:6 Contents of /tmp/wtf.log ::0 Some sort of security setting in php.ini maybe? If so, I'm not only curious in how to fix it but also how this actually happens. Does the value assigned to $writeline not get immediately evaluated? I mean, does $writeline know it contains variables from elsewhere, instead of just containing a string of chars?

How I can solve this ? How you store things in tables can sometimes get a little tricky. One way to approach this is with normalized tables and using joins in your query like you are doing. To make this work, in your main entries table, have a field that indicates what the entry type is. If you are doing one select that gets both articles and news stories, having that extra field can help you distinguish what type it is, and which fields contain data in each record. (cf: Wordpress wp_posts table for an example of how this is done. They store posts, pages, and attachments in a single table this way. I can't say if this is a better arrangement than keeping them in separate tables.) I've had to hack this table. It's a prime example of bad design. Take a long look at the records of this table in an active blog, with a survey of each of the fields and their values. You'll see what I mean. Paul The Drupal approach to this problem is to have a common table for all nodes (our generic content object thingie), and then dependent tables for type-specific stuff. So (over-simplifying): node: id, title, type, created time, updated time, published (1 or 0) field_body: node_id, delta, value field_picture: node_id, delta, url field_source: node_id, delta, url to reuters or whatever field_writers: node_id, delta, writer name, url to writer picture // etc. That way, you can have the basic information all in one table and then specific fields can be shared by some, all, or just one node type, and all can be multi-value. It does mean loading up a full object is multiple queries, but really, MySQL is fast. You don't need to over-optimize your query count, and this gets you a well-normalized database. If you know in advance exactly what your types are going to be (in Drupal they're user-configurable), you could simplify it to something like: node: id, title, type, body. created time, updated time, published (1 or 0) node_article: node_id, writer name, writer picture url node_news: node_id, url to reuters or whatever And you can still select on whatever you need. With a LEFT JOIN, you can even get back all data on all articles of both types, and just have lost of nulls in the result set for the off-record fields. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP exercises
Hi folks. A friend of mine is trying to learn PHP. She already knows programming basics, but wants to learn PHP specifically. However, she learns much better with assignments or exercises than just from reading articles or books.

Can anyone recommend other sources for tutorial-based or exercise-based PHP learning? Paid is OK if it's not too expensive and it's worth the money, although free is always preferred.

[PHP] Books on PHP guts
Hi folks. I'm not looking to write new PHP extensions per se, but am looking to better grok the guts of PHP itself. (That's a first step on the way to writing new extensions, though. Gateway drug!) I'm especially interested in the memory/performance implications of various techniques. Are there any good books on the subject that would be of help? I'm familiar with Sara Goleman's book[1], which has generally good reviews, but it's several years old now and I'm not sure if there's anything newer that covers PHP developments since the 5.0 days.

--Larry Garfield
You mean requiring explicit declaration of
class Bob implements Foo {
}
It's so you can guarantee your app from future breakage because the
interface guarantees minimum functionality and still maintain great
flexibility such that:
Well, let me offer a more precise example of what I want to do:
interface Stuff {
function doStuff($a);
}
interface Things extends Stuff {
function doThings($a);
}
class Bob implements Stuff {...}
class Alice implements Stuff {...}
class George {}
class Matt implements Things {...}
function make_stuff_happen($o) {
foreach (class_that_implements_stuff() as $class) {
$c = new $class();
$c-doStuff($o);
}
}
The above code should iterate over Bob, Alice, and Matt, but not George. The
trick is how to implement class_that_implements_stuff() (or rather,
class_that_implements_something('Stuff')) in a sane and performant fashion
that supports auto-loading.
If all of the above is together in a single file, it's dead simple with
get_declared_classes() and class_implements(). However, in practice there
could be some 200 interfaces -- with each installation having a different set
of them -- and as many as 500 classes implementing some combination of those
interfaces, possibly multiple on the same class -- also with each installation
having a different set of them. I do not want to be forced to include all of
those classes and interfaces on every page load when in practice only perhaps
two dozen will be needed on a particular request. That makes
class_that_implements_stuff() considerably tricker.
That let naturally to having a cached index (in a database, in a file with a
big lookup array, whatever) that pre-computed which class implements what
interface and what file it lives in, so that we can easily lookup what classes
we need and then let the autoloader find them. (Previous benchmarks have
shown that an index-based autoloader is actually pretty darned fast.) That
just makes building that index the challenge, hence this email thread.
Thinking it through, however, I am now wondering if, in practice, indirect
implementation (class Matt above) will even be that common. It may not be
common enough to be an issue in practice, so requiring Matt to be declared as:
class Matt implements Stuff, Things {...}
isn't really that big of a deal and makes the indexer considerably simpler.
We actually have one already that indexes class locations; it just doesn't
track interfaces.
I also, on further review, don't think that class-based inheritance will ever
be an issue. The following:
class Mary extends Alice {...}
Would not make much sense at all because then both Mary and Alice would run,
so Alice's code would run twice. So I may be over-complicating the situation.
(For those following along at home, yes, this is essentially observer pattern.
However, it's on a very large scale and the thing being observed may not
always be an object, so the usual active registration process of instantiating
both objects and telling them about each other on the off chance that they
*may* be needed is excessively wasteful.)
Does that make it clearer what I'm trying to do?

[PHP] Class and interface location
Hi all. I'm trying to come up with a solution to an architectural problem I could use some extra eyes on. I have (or will have) a large code base with lots of classes, spread out over many optional plugin components. These classes, of course, will have interfaces on them. These classes will, of course, lazy-load using PHP's autoload capability. What I need to know is which classes implement which interfaces, so that I can load and use all classes that implement interface Foo. There are a couple of approaches that I've considered, all of which I dislike for one reason or another. 1) Magic file naming. That is, any class that implements interface Foo lives in a $something.Foo.inc file, or some similar pattern. This has a number of problems. First, it means a huge number of file_exists() calls to determine if a given potential class exists, and then disk hits to load those files. While that information is possible to cache, it also means that we cannot have a class that implements two of the interfaces I'm interested in (a feature I will need) because then it would have to live in two files, which is clearly impossible. 2) Reflection. PHP makes it quite easy to get a list of all loaded classes, and to get a list of all interfaces that a loaded class implements. The catch there is loaded. Reflection only works once you've loaded the code file into memory. Once you've done so, you cannot unload it. That means the code is sitting there in memory wasting space. Given the size of the code base in question, that could easily blow out the process memory limit. Even if we cache that information we derive from reflection we still have to load it the first time (or periodically when rebuilding the cache), which will blow the memory limit. The only alternative would be to have some sort of incremental rebuild across a multi-request batch process, the complexity of which makes my skin crawl. 3) Static analysis. Instead of reflection, either tokenize or string parse all files to determine what classes implement what interfaces and then cache that information. We are actually using this method now to locate classes, and it works surprisingly well. Because we never parse code into memory it does not ever spike the memory usage. However, it is impossible to determine if a class implements a given interface by static analysis unless it declare so itself with the implements keyword. If it does so indirectly via inheritance, either via the class or via the interface, it would not find it. That necessitates that any detectable classes must explicitly themselves declare their interfaces, even if it is redundant to do so. I don't like that approach, but it's the first one that strikes me as even viable. 4) Explicit declaration. In this approach we detect nothing and rely on the plugin developer to do everything. That is, they must provide somewhere (either in code or a configuration file) an index of all classes they offer, the interfaces they implement, and the file in which they live. While this makes the implementation easy, it is a huge burden on the plugin developer and I'm quite sure they'll forget to do so or get it wrong on a regular basis. 5) Wave a wand and let the magic ponies figure it out. I wish. :-) Can anyone suggest a better alternative? At the moment option 3 seems like the most viable approach, but I'm not wild about the implied performance impact nor the potentially redundant interface definitions it would require. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Stay tuned. :-) Larry - how many databases does it actually work with? Having rebuilt the DB layer using PDO did you actually gain anything? Drupal 6 and earlier supported MySQL and, kinda sorta, Postgres, maybe. Drupal 7 ships with support for MySQL, Postgres, and SQLite out of the box and add-on modules provide support for Oracle and MS SQL, within reason. So we increased our DB support from 1.5 to 5, essentially. We also gained, as part of the rewrite, untyped prepared statements, transactions, and master/slave support (although that's nothing to do with PDO per se, just our layer on top of it). And that allowed us, in turn, to build type-safe query builders, support for MERGE queries, and all kinds of other fun stuff on top of that. PDO still needs a number of areas finishing before it can become a total replacement for the legacy stuff that is available such as the PEAR libraries and the likes of Drupal writing their own abstraction layer on top of it ... along with a number of other projects who are now doing the same thing ... shows that PDO is not creating the common platform it was supposed to :( That is, sadly, true. PDO is not a complete and perfect DB library, in part because there are few people who work on it, and fewer still who understand all of the vendor-specific issues at hand and the vendors have been very slow to lend a hand, preferring to work on proprietary APIs. It's quite unfortunate, but I still consider PDO an overall win.

The point of a common framework is to trade a small bit of performance for a large amount of developer time. If you will only use the framework once, the payoff will be much less. The goal is to choose frameworks that you can leverage again and again. As for training, you will be able to hire another developer that knows Doctrine. It will be impossible to find a developer *anywhere* that understands your home-grown framework without training.

I will do this if the options out there don't suit my needs or if they seem under-supported.

[PHP] Disk IO performance
There are many things that everybody knows about optimizing PHP code. One of them is that one of the most expensive parts of the process is loading code off of disk and compiling it, which is why opcode caches are such a bit performance boost. The corollary to that, of course, is that more files = more IO and therefore more of a performance hit. But... this is 'effin 2010. It's almost bloody 2011. Operating systems are smart. They already have 14 levels of caching built into them from hard drive micro-controller to RAM to CPU cache to OS. I've heard from other people (who should know) that the IO cost of doing a file_exists() or other stat calls is almost non-existent because a modern OS caches that, and with OS-based file caching even reading small files off disk (the size that most PHP source files are) is not as slow as we think. Personally, I don't know. I am not an OS engineer and haven't benchmarked such things, nor am I really competent to do so. However, it makes a huge impact on the way one structures a large PHP program as the performance trade- offs of huge files with massive unused code (that has to be compiled) vs the cost of reading lots of separate files from disk (more IO) is highly dependent on the speed of the aforementioned IO and of compilation. So... does anyone have any actual, hard data here? I don't mean I think or in my experience. I am looking for hard benchmarks, profiling, or writeups of how OS (Linux specifically if it matters) file caching works in 2010, not in 1998.

I have an app that runs just fine on an older Solaris apache server (Apache/2.0.53 PHP/5.0.4), but when I run the same app on a newer Linux server (Apache/2.2.3-11 PHP/5.2.8) against the same database on the same mysql server, it fails with Allowed memory size exhausted. This occurs on a: $result = mysql_query($query, $db) statement. Both servers are running the identical query, which returns a result set under 0.5M. The Solaris server is configured with memory_limit = 8M in php.ini, and the Linux one with 32M, so clearly something other then what I'm seeing is going on. Anyone know what could be causing this? Any php or apache build or config options that I could look at? TIA! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Any php or apache build or config options that I could look at? TIA! Is there any other place which your code is changing the memory_limit parameter? I would assume this is unlikely, but sometimes even the unlikely happens more than than it should! The error message actually says Allowed memory size of 3355432 bytes exhausted so I know it's using the 32M that it's set to php.ini. But as I wrote above, on the Solaris server where it works, the memory_limit is set to 8M. Can you maybe strip the code down to a test case which causes the error? I've already done that - all it does it run a query and display the results. Lastly, I do notice that you've got two different versions of PHP Apache installed on each OS, which could be the reason for the failure. Well, yes, that's what I said. And they may been built with different config options. But what options could cause a difference like this? Maybe set up a VM or two to test things out. Have one VM with Solaris and Apache/2.2.3-11 PHP/5.2.8, and another VM with Apache/2.0.53 PHP/5.0.4 and see what happens. It could be that it's either Apache or PHP or both causing the problems on your Linux system. I don't have control of that. This is at a client site - they want to get rid of their existing older Solaris apache server and move to a newer Linux one. The servers are already set up they way they are. I asked the admis for info on the build - they have it for the newer Linux one, but not for the older Solaris one. They did give me another machine to test on - that one is Linux, Apache 2.2.3, PHP 5.2.6 - that also gets the out of memory error. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] CakePHP, alternatives?
One other thing I will add: Don't just learn PHP. Learn Javascript as well. Don't treat it as PHP without dollar signs, but learn Javascript as Javascript, and PHP as PHP. Then after you've gotten some time with those, take some time to learn, or at least learn about even if you never work with it, Erlang. Or Haskel. Or some other stricter, purely functional language. Something that works totally differently than PHP. Even if you don't ever use it, the perspective you gain from approaching a problem from a different angle will help you learn about the strengths and weaknesses of different languages, different ways of thinking, different ways of leveraging your tools well, etc. The 6 hours or so I spent reading about Erlang and purely functional languages helped my PHP skills considerably, even though I never wrote a single line of Erlang. (I was already very solid in PHP at the time, but it made me even better.) --Larry Garfield On Saturday 05 June 2010 12:51:47 am Shreyas wrote: @ All - Points duly noted.

Re: [PHP] iCal parsing and processing
Hm. Thanks, but it looks like that's all in Python.

I am looking for a good iCal processing library (open source / GPL compatible). Unfortunately, everything I've been able to find so far is half-assed, incomplete, buggy, or so horribly designed that I'd be embarrassed to use it (or several of the above). I was hoping someone could recommend one that actually works. I'd prefer an OO interface as it seems a natural fit, but at this point I'll settle for whatever works. I am not looking for an application with UI and form integration and stuff. I just want a working stand-alone parser. (If it can be ripped out of something more complete, that's fine.) My needs: 1) Given raw data (provided by a user form that I can already handle), construct iCal VEVENT information including RRULEs and EXRULEs. 2) Given a VCALENDAR / VEVENT object, generate the appropriate iCal text string that I can write to a file or return to the browser with the appropriate mime header. 3) Given a VCALENDAR / VEVENT object with RRULEs and EXRULEs in it, be able to say give me the start/end dates of the next X occurrences from some date or give me all the start/end dates of occurrences until date Y. What I've found so far: http://www.kigkonsult.se/iCalcreator/ - This is the best I've found so far, and it's what I'm using now. It's missing requirement #3, though, as near as I can tell. Actually if I could add that functionality to it without too much trouble I'd probably stick with it, but it's non-trivial functionality. It's also PHP 4 OO, but I can deal. http://phpicalendar.net/ - This claims to do #3, I think, but it's integrated into a web app. The code for it is also horrific, as the entire parser is build on include files that rely on global variables without using any functions. The security implications of that alone scare me to death to say nothing of side effects and stability. http://code.google.com/p/qcal/ - Documentation is sorely lacking, as it is listed as pre-alpha, real alpha to be released in January. That post was made in December, and there's still no real alpha. :-) So I can't really tell if it does what I need or not. A quick search turned up nothing in PEAR, and Zend Framework has only a proposal from 2 years ago, not an actual library. Any others I don't know about? This seems like an area that cries out for a good standard library, but as of yet I haven't found one that works.

Re: [PHP] class attributes and __construct
On Thursday 15 April 2010 08:37:40 am Ashley Sheridan wrote: I know I could move it to __construct and give it a default value in the arguments list, but that brings it's own problems. What if the argument list grows too big, and which attribute would be deemed more important than another that you might want to override it without specifying every other? Is there a rule of thumb as to what belongs in __construct and what does not? Thanks, Ash http://www.ashleysheridan.co.uk I tend to favor setting the default with the property itself rather than in the constructor, even if I expect the constructor to specify it. I really really hate having undefined variables. :-) So even if, for instance, I'm going to pass in a db connection object in the constructor I will define it in the class and set it to NULL rather than not setting to anything.

[PHP] Constructor usage
Hi folks. Somewhat philosophical question here.
I have heard, although not confirmed, that the trend in the Java world in the
past several years has been away from constructors. That is, rather than
this:
class Foo {
public void Foo(Object a, Object b, Object c) {}
}
Foo f = new Foo(a, b, c);
The preference is now for this:
class Foo {
public void setA(Object a) {}
public void setB(Object b) {}
public void setC(Object c) {}
}
Foo f = new Foo(a, b, c);
f.setA(a);
f.setB(b);
f.setC(c);
I suppose there is some logic there when working with factories, which you
should be doing in general. However, I don't know if that makes the same
degree of sense in PHP, even though the OO models are quite similar.
So, I'll throw the question out. Who uses example 1 above vs. example 2 when
writing dependency-injection-based OOP? Why? What trade-offs have you
encountered, and was it worth it?

What trade-offs have you encountered, and was it worth it? One problem I have with parameterless constructors is this: When you rely on setters to shape your object rather than the constructor, your other methods cannot assume the object is in proper shape to be usable. There's no guarantee the programmer won't forget one of the vital setters. So each method in the object must test to ensure the object can actually be used properly. This isn't a deal-breaker, but it seems like an awfully unnecessary piece of additional code which must be replicated in each method. (Naturally, this is moot where the class doesn't depend on any outside objects or parameters to operate.) Yeah, I tend toward using constructors for injection for the same reason: That way I always know for sure that if I have an object, it's complete. I defer most object instantiation to factories anyway, so in practice it's not a huge issue for me. I've found that many of my classes require other classes in order to operate. Moreover, they must be instantiated in the proper order, or things fall apart. So I took the step of creating my own dependency injection instantiator class which handles all this for me. Classes with dependencies typically are specified so that the requisite objects are passed to the constructor (the simplest way). Each class which is managed by the DII is registered first, with whatever parameter or object dependencies needed. Then the DII's instantiate() method is called as needed for each object. The DII class handles instantiating objects in the proper order and with the proper dependencies. The programmer's job is made much simpler. Paul Sounds overly complicated, but whatever works. :-) In my experience so far I find that a well-designed factory is sufficient, but it may not be in larger or more involved OO frameworks than I've used to date. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Will PHP ever grow up and have threading?
Perhaps if you asked a question you'd get an answer rather than coming off as an angry immature crybaby in your last paragraph... No, I'm not going to dignify your post with a real answer.

The one problem that seems to always keep coming back on enterprise level projects is the lack of threading. This always means we have to write some back-end code in Ruby or Java or C/C++ and some hacky database layer or DBUS or something to communicate with PHP. Will PHP ever have proper threading? It would sure let the language take the next logical leap to writing applications and daemons. I love the idea that Rails/Ruby have where you can just load objects in memory once and keep using them from page to page (this is NOT the same as a $_SESSION, it's way more flexible and powerful). But more importantly, in one application I'm working on, we need to connect to an Asterisk system for the IVR abilities. This means we have Ruby doing all that fun stuff and PHP doing the web stuff, but we're also duplicating a LOT of work. Both Ruby AND PHP now have to have ORMs for the user who's calling in, advertisements served, products shown, etc. We could have used Rails for the web portion, but I want to stay with PHP and I'm sure I don't have to explain to you PHPers why that is. Without threads, PHP just isn't even an option or only one user would be able to call in at a time. The pcntl stuff is not feasible. It's a hack at best. Spawning multiple scripts is also a recipie for disaster. When will the PHP core-devs (Zend?) realize that PHP is much more than a hook to a database. It's much more than web pages. Is this a case of it's too hard? Or is it a case of PHP core developers just being douche-bags like they are about the whole foo($set_this_parameter=$bar); bull$hit??! (there is NO reason NOT to let the developer choose WHICH of the list of parameters they want to set in a function/method call aside from being stubborn!

[PHP] Code samples in OOo Presenter
Hi all. I have a busy conference season coming up, and will be giving a number of presentations that involve code, specifically PHP. I am going to want to put code onto slides in OpenOffice (3.1 specifically, using Kubuntu 9.10), but to date I've never figured out a good way to do that. Anyone know of a good way to do syntax-highlighted code in OOo? Things I've tried in the past: 1) Just throw code onto the slide, no highlighting. This works, but is ugly and harder to read or demonstrate what I am doing. It's my usual fallback. 2) Screen-shot from a web page that uses syntax highlighting, such as PHP's built-in highlighting. Very difficult to prepare since the sizing is usually all off. Ugly. Very difficult to edit and change because the screen caps have to be regenerated. And PHP's default coloring for highlighting frequently clashes with the slides and looks godawful on a projector. (I once ended up with blue text on a black slide. That was a major fail.) 3) Jump out of the slides into an IDE. Works, but totally breaks the flow of the presentation. The IDE usually also has text that's way too small, and I have to reconfigure it into a presentation mode, often on the fly. It also makes discrete snippets harder to show, since there's still the entire rest of the IDE there. I don't like any of these options. :-) I don't know what the alternative is, though. Ideally I'd love to have a custom text region or format or something that is take this and highlight it properly, but I don't know if such a plugin exists. I could be talked into using KPresenter / KOffice instead if that would be easier, but as I am on Linux I have no access to KeyNote or PowerPoint. Any suggestions? --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It should then preserve the formatting used on the browser display, and let you easily modify the font size. Thanks, Ash http://www.ashleysheridan.co.uk I will have to see if OOo preserves formatting when I do that. However, that still leaves the problem of highlight_string()'s colors being rather poor for on-screen. Are those easily configurable? That would at least give me a decent result, kinda, even if it's not as clean as doing it all within the presentation program. --Larry Garfield -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
