Re: [PHP] Re: PHP as Application Server
On 9/26/12 10:18, Matijn Woudt tijn...@gmail.com wrote: Writing scripts for an application server requires a much deeper understanding of threads and computer internals,so as a result it probably increases error rate. Well... yes and no. PHP's architecture pretty much keeps you from having to mess with thread management, but it does so by shifting the burden to a higher level, either process management of multiple PHP processes or thread management within the context of the HTTP server. If your application is sufficiently simple, that shift may be enough to keep you from having to worry about the problem. For most applications, however, it's still a concern. In some ways, this can make things worse, simply because PHP programmers tend to be oblivious of the potential problems, whereas the typical C# or Java programmer has at least some awareness of the various traps that await them. As an example, I see PHP code *all the time* that is wide open to concurrency issues with the database. Most code just assumes it's the only code doing updates, but unless the server is set up to serialize requests, that's an invalid assumption. Recently, more folks have started to address this by using database transactions, but this is often done in ignorance of what isolation level is being used and what the impact of that is upon the code - which can just make things worse. Even when there is that awareness, there are database concurrency issues with which transactions can't help. (Of course, people who are aware of isolation levels also tend to be aware of other concurrency issues.) The point is, if you have multiple things running in parallel, whether that be threads within your application or entirely separate physical servers running multiple copies of your application, you have to deal with concurrency issues. It's a necessary evil of parallel programming, and no mere technological solution (language, database, whatever), now or in the future, can fully overcome it. Well, maybe an AI engine somewhere in the chain, but that's about it, and that's not coming anytime soon. Incidentally, another advantage of PHP's share-nothing approach that hasn't been mentioned is relatively easy scalability. In a shared pool architecture, the easiest way to scale is typically vertically, that is, adding RAM, faster drives, etc. This is fine, but you can only scale vertically to a certain point, which you can usually hit pretty quickly. With PHP's share-nothing approach, you can still scale vertically, but you can almost as easily scale horizontally by adding more servers that each run merrily in their own worlds, with the primary added coordination logic being in the areas of communicating with the database and the data cache, something the application should be designed with, anyway. In contrast, the shared approach requires added logic, somewhere, to coordinate the sharing amongst the pools of all that data that the application takes for granted is always available at low cost. Having said all that, there are many advantages and disadvantages to both approaches. And honestly, I would love to have the option of a shared approach with PHP, since that architecture simply works better as a solution to certain problems. Assuming the shared-nothing model continues on, it would make PHP that much more well-rounded. In that respect, the added option isn't that different from the addition of OOP: we now have the great ability to use procedural code where it makes sense, and to use OOP code where it makes sense. Where neither is a perfect fit, you can choose the one that creates the least personal pain. It's a wonderful choice to have. Regards, Bob -- Robert E.

Re: [PHP] Reading class variable value always returns NULL
I'm not real clear on what's happening. Are you saying that if you assign
values to the protected class members, and then immediately read them,
that they're null? So, there's code something like this:
class Foo {
public function Something() {
$this-foo = 1;
//shows null instead of 1
var_dump($this-foo);
}
protected $foo;
}
Is that right?

Re: [PHP] Entry point of an MVC framework
On 7/12/12 13:21, Simon Dániel simondan...@gmail.com wrote:
And I can't do it with the constructor of the inherited
class, becouse this way I would overwrite the parent constructor.
Just call to the parent constructor from the child:
public function __construct() {
parent::__construct();
//do whatever
}
You can call it at any point, so you could do some setup stuff and then
call it, or call it and then do more setup stuff. Basically, you get to
augment the functionality of the parent constructor.
And as far as I know, it is not a good practice to call a method outside
of the class, becouse the concept of operation of the class should be
hidden from the other parts of the application.
Calling methods of other classes is quite normal, and in fact, necessary
in most cases. The trick is that each class specifically decides which
methods it wants to allow outside code to call, which it wants only
children classes to call, and which should only be called internally.
Classes do this by declaring methods as public, protected, or private,
respectively.
http://us.php.net/manual/en/language.oop5.visibility.php
What you do want to aim for is a stable set of public methods, which means
that the names of existing methods and the parameters they take don¹t
change when you update the class. If you maintain this stability, then you
can make all the updates you want but not have to update any other code
using the classes. If you change the public methods (that is, change the
class API), then you'll break other code that's using those methods.
Another consideration, and one which you're also touching on, is that of
handling dependencies. If your class requires some other class to
function, you ideally should hand it an instance of the other class,
versus directly instantiating it. You can do this in a variety of ways,
but the most common are passing the object as a parameter to the class
constructor and passing it via an injection method. What you gain by doing
this is that if you want to change the behavior of the class (e.g., by
passing it an object that sends a message by SMS instead of the one it
previously used that sent messages by e-mail), it's a simple matter of
passing a different type of object that has the same public API. This also
makes testing quite a bit easier, since you can pass mock objects that
just pretend to do the functionality of the real ones, thus allowing you
to test the main class without worrying about whether all the secondary
classes upon which it relies will break anything. When you're ready to
learn more about this, do a Google search for php (inversion of control).

[PHP] How does this code work?
I found this code in a user comment in the PHP docs for htmlentities():
?php
function xml_character_encode($string, $trans='') {
$trans = (is_array($trans)) ? $trans :
get_html_translation_table(HTML_ENTITIES, ENT_QUOTES);
foreach ($trans as $k=$v)
$trans[$k]= #.ord($k).;;
return strtr($string, $trans);
}
?
It seems to work. For instance, this (assuming UTF-8 encoding):
echo xml_character_encode('Château');
echo \n;
echo xml_character_encode('Chteau');
Yields this:
Ch#195;#162;teau
Ch#38;teau
My question is, *how* does it work? It makes sense right up to the return
statement. According to the docs for strstr(), when a non-string is passed in
as the needle, it's, converted to an integer and applied as the ordinal value
of a character. First, an array-to-int conversion is undefined, though it
seems to produce 1 on my copy of PHP. Now, I'm not quite sure how to interpret
the last part of that statement from the docs, but I take it that the ultimate
value supplied to strstr() is going to be either '1' (the character value of
the integer value of the array) or '49' (the ordinal value of the character
'1'). Whatever, neither one makes sense to look for in the haystack, so I'm
obviously missing something.
Perhaps it's just late-Monday slowness on my part, but what's going on here? I
have no intention of using this code, but I'd sure like to understand how it
works!

Bob

Yes, this is correct. I'm not sure if Apple started doing this with Lion or before, but they give you the .default file to rename (or better, copy) as php.ini if you desire. Note that the .default file isn't actually used by PHP, but rather is merely intended to be used as a template. Also, if I remember right, Apple sets up Apache so that each user has his/her own config file inside the conf folder. You should make any config changes, such as turning on PHP, in there, rather than in the primary config file. The latter is subject to being overwritten on OS updates and upgrades, while the former is not. Segregating your changes also makes it easier to tell exactly what you've changed from the defaults. I'm however carefully ensuring that the client and server aspects of my app (which will both run on the user's machine) don't use anything except what comes with the standard OS X distribution, so to fix the date time issue I do: date_default_timezone_set (@date_default_timezone_get ()); I recommend against this. First of all, in PHP 5.4, this is just going to return UTC if you haven't explicitly set the time zone, and that's probably not what you want. Plus, the use of @ here leaves a nasty taste in the mouth (as it does in most cases). Instead, I suggest creating a php.ini file and changing this setting there by setting it to a specific time zone. For example, in mine, I have this line: date.timezone = 'America/Phoenix' This ensures that PHP is always using the same zone no matter what script is running, avoids PHP errors if you forget to make the change in a script, avoids you having to modify all your scripts in the first place, and lets you easily change the time zone used by your applications to whatever you want independently of the server's own time zone (or in 5.4, to something other than UTC).

When the user starts the app, I create an apache config file on the fly and run an instance of apache just for the user. So I'm not messing with the standard OS X Web Sharing. For the same reason, I don't want to start modifying or creating a php.ini file. In that case, you might consider setting it via the Apache config file that you're creating, which you can do with something like: php_value date.timezone 'America/Phoenix' That'll have the same effect (and benefits) as setting it via php.ini. Hmm, just looked more carefully at the docs. I see I'm going to have to add a prefs setting so the user can tell my app what timezone they are in. I find it odd that the OS can't provide this information. Well, it typically can, or at least can make a guess at it. The problem is that it's not something you can rely on across different OSes, as some handle it differently, or less reliably, or not at all. Basically, the result is non-deterministic. It's for this reason that, as of 5.4, PHP won't even ask the OS but will always return UTC (and complain a bit) if something else hasn't been set. This way, you at least have a chance of consistent results. If you're only supporting OS X, you can have your script that generates the Apache config file retrieve the system time zone, and then use that value in the php_value setting. If the script is in PHP, you can do this: $timeZone = `/usr/sbin/systemsetup -gettimezone`; Which just calls the systemsetup command line utility (basically, a CLI front-end to the settings controlled via System Preferences). Here's what that call returns when run on the command line on my system: H012316WHPV:~ rewilliams$ systemsetup -gettimezone Time Zone: America/Phoenix Regards, Bob -- Robert E.

The problem is that your expression basically defines a 'contains'-type
search, so it's matching the first 10 characters as required but then
simply ignoring that last, 11th character because there's no requirement
regarding it in the expression.
Try this instead:
^(\d{4}-\d{2}-\d{2})$
The ^ anchors the matching string to the beginning of the string, while
the $ anchors it to the end, which effectively forces the expression to
match the entire string, disallowing extra characters before or after it.

My suspicion is that there's is an unmatched curly brace earlier in the

further down the file--sometimes way down--because the parser can't
recognize until it hits the later point that something is wrong. Try
double-checking that the {Š} blocks prior to line 1050 properly balance,
and you'll probably find there's an extra one, or that one is missing, etc.
If nothing else, just start stripping code from the file until you find
the line that's actually at fault. If you do this in a binary search
fashion, it won't take more than a few minutes.

Re: [PHP] How can I check for characters in a $_POST[] variable?
As an alternative to the regular expression approaches already provided by
others, you could also use ctype_alnum():
if (ctyp_alnum($_POST['username'])) {
//username contains only letters and numbers
} else {
//username contains characters other than letters and numbers
} //if-else
Docs: http://us3.php.net/manual/en/function.ctype-alnum.php
As a bonus, this will likely be quite a bit quicker than the regex-based
approaches. That said, you'd have to be making many calls (e.g., inside a
loop) for the difference to reach the point of being noticeable. For
something like a one-time validation on page-load, use whichever you find
most comfortable.
In your original question, you also mentioned looping through a variable
to check for non-alphanumeric characters. The regex approach or the
approach I outlined above is much better in this case, but as a learning
exercise, you could do the looping like this:
$validCharacters = array('a', 'e', 'i', 'o', 'u');
for ($i = 0; $i count($_POST['username']); $i++) {
if (in_array($_POST['username'][$i], $validCharacters)) {
echo 'Pass!';
} else {
echo 'Fail!';
} //if-else
} //for i
The key thing to note there is that you can treat the string like it's an
array to loop through it. For more information about this, go here:
http://us2.php.net/manual/en/language.types.string.php
and search the page for the phrase String access and modification by
character.

Re: [PHP] How can I check for characters in a $_POST[] variable?
[Redirecting thread back to the list for the benefit of others.]
On 9/22/11 13:38, Eric eric_justin_al...@cfl.rr.com wrote:
So is $_POST[username][0] appropriate or does that only work
with normal variables?
As far as this sort of manipulation goes, $_POST is just like any other
variable. Referencing the 0th element of any string will give you the
first character, if there is one. (If there isn't one, you'll generate a
PHP warning or notice for trying to read out-of-bounds.)
and would this be valid,
$i = 0;
while($_POST[username][$i] != \0)
It looks like you're trying to treat the string as a C-style string. That
won't work in PHP because PHP's strings are not null-terminated. Thus,
this will lead to an infinite loop with any strings that don't happen to
have the null character somewhere within (and most strings won't).
{
if($_POST[username][$i] == . || $_POST[username][$i] == ..)
This line is not wrong per-se, but nor does it entirely make sense. When
you access a string as an array, each element contains one character.
Here, you're checking whether each character in turn is a period (fine) or
two periods (makes no sense, since one character cannot represent two
period characters). What you'd probably want to do is simply remove the
second condition, since a check for one period will work just as well if
the name contains two periods. That is:
if($_POST[username][$i] == .)
Incidentally, another tip: when comparing against a constant, as you are
in both your while() and your if(), place the constant on the left side if
the expression rather than the right. That is, write the previous if()
like this:
if ('.' == $_POST['username'])
It might look a little funny, but I assure you, someday, it'll save you a
bunch of frustrating debugging time. The reason is that if you mistype the
'==' as '=', you'll do an assignment, the value of which is then returned.
This has the net effect of 1) quietly changing your variable's value, and
2) making the overall expression always evaluate to true, sending you into
the the true part of the conditional branch, well, unconditionally.

[PHP] Mysqli error handling
Okay, so I've finally got an opportunity to start converting our code to use Mysqli instead of the old mysql_* functions. Mysqli is new to me, but I thought things were going well until the first time I tried to run a query with a syntax error in it, and it threw up a PHP warning. Being that Mysqli is an OO API, I guess I assumed that any errors would simply surface as exceptions, and indeed, I got an exception in this case. But I also got a PHP warning containing the same information. This is the first thing that strikes me as terribly wrong. I think any API, OO or not, should never spit out errors/warnings/notices for routine errors (like, in this case, an SQL syntax error). Rather, the function/method should signal an error through a defined mechanism, such as the return value (e.g., false on failure), or via an exception for class methods. This philosophy jives well with my understand of the direction of error handling in PHP, which is to use exceptions, rather than errors/warnings/notices, for all the newer OOP APIs. Secondly, I can't find a good way to handle these warnings. We do all development with error handling set to E_STRICT | E_ALL, and our general policy is that no such errors should be generated. This behavior by Mysqli means that we effectively need to catch SQL problems in both our error handlers and in our exception handling. I recognize that we could just use suppression, but that's, well, nasty. Digging a bit more, I found mysqli_report(). This looks pretty good, but I find it odd that 1) it's a procedural-only function that controls an OO API, and 2), it takes affect for the entire request, which effectively means it has to be set up right for each database access rather than just once per database instance. I suspect this relates to the underlying implementation, but it's still quite the letdown. Is there something I'm missing in all this, or is really as clunky as it seems? What have those of you with more Mysqli experience found to work well as a good error-handling pattern when working with it? -- Robert E.

Re: [PHP] Constants in strings
On 2011-07-6 08:09, ad...@buskirkgraphics.com ad...@buskirkgraphics.com wrote: I use constants in my OOP and I never use the heredoc syntax. Now I am fearing that I have not taken advantage of something. My understanding of heredoc syntax as of 5.3 is just a string quoting right? Is there an advantage of using the heredoc syntax over single quoted or double quoted? I don't believe that a heredoc will perform significantly differently than a double-quoted string, as, from the parser's POV, they're essentially the same thing once you get past the step of extracting the entire string from the source. I've not verified this by reviewing the relevant source, however, nor have I benchmarked it. But, I'm willing to bit that even if there is a difference, it's so small that you're better off worrying about which will lead to easier code maintenance than worrying about performance (as is typically the case with such micro-optimization choices). In my view, what's important is how you use them. In particular, a heredoc can present a bit more cleanly when you're dealing with a large-ish chunk of text, as in, say, an e-mail message template. The main downside is that they will usually make a mess of code formatting, since the closing delimiter must be against the left margin. For this reason, I tend to prefer multi-line double-quoted strings over heredocs when I have meaningful indentation, as in a function or class method. Where I've made most use of heredocs is when I want to do nothing but define a bunch of long strings in one file. For example, I might create a file to define a set of related e-mail message templates: ?php $accountCreationSuccessfulMessage = EndSuccess Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.
