[PHP] "public static" or "static public"?
OK, so it's a Friday hence a random debate
What is preferred for class methods?
class foo
{
static public function bar(){}
public static function wibble(){}
}
??
All methods are valid, but are some more valid than others? :p
Checking ZF:
[colin@jimmy Zend (working)]$ cgrep "public static function" . |wc -l
755
[colin@jimmy Zend (working)]$ cgrep "static public function" . |wc -l
60
It's clear which is preferred there, but still not absolutely consistent
(I didn't bother checking differently scoped methods).
I personally prefer scope first then "static", but others may have valid
reasons/arguments for preferring the other way.
WDYT?

I'd implement the above as a static "factory" method of your primary
class: e.g.
> class MainClass {
public static function factory($args = null) {
$plugin_class = __CLASS__ . 'Plugin';
// Assume autoloading
if (class_exists($plugin_class))
return new $plugin_class($args);
return new self($args);
}
protected function __construct($args) {
}
> function doSomething( $args ) {

And replace this line with:
$main_class = MainClass::factory();
> $main_class->doSomething( 'foo' );
Which, when run, does indeed produce your desired results.

Well difference techniques require different approaches, but certainly a
factory approach is likely the correct design solution here to get the
desired results.
Full code for convenience:
doSomething( 'foo' );

In all seriousness tho', where do you ever provide a two bit number? $n = 2; The above is a number, it's not implicitly a two bit number... I mean, if I do: $n = 2; $n += 2; What do I get then? $n == 0? That's what *should* happen if $n was indeed two bits. It would overflow and wrap around.

The output looks correct to me, so I think it's your expectations that are incorrect. You are assuming that you are working with a 2-bit number the in actual fact you are working with a 32-bit number. If you did $bin = 2; $notbin = ~$bin & 3; Then this should get the results you want. The bitwise & 3 bit essentially limits things to a 2-bit number. (3 in binary is represented by 1's for the two LSBs and 0's for all other bits).

This is a neat trick! Yeah that will avoid the need for the static lookup table with 32 randomised columns. Jon's strategy is more or less a simplified version of my 32-column randomising table (i.e. just have 1 column of random data rather than 32). I would personally prefer to reduce the refresh of this data as I don't like to annoy people when the change over day happens. The RAND(seed) approach will probably work well (not sure of performance verses an indexed table, but I can easily experiment with this). If I use the numbers 1..32 as my seed, then I still get the same net result as a 32 column table. If I just change my "seed offset" then I get the same result as re-generating my random data tables. >From an operational perspective, RAND(seed) is certainly easier. I'll certainly look into this.

[PHP] Dear Lazy Web: Pseudo Randomisation Strategies on Listing Websites
Hi, OK, this is really just a sounding board for a couple ideas I'm mulling over regarding a pseudo-randomisation system for some websites I'm doing. Any thoughts on the subject greatly appreciated! Back Story: We have a system that lists things. The things are broken down by category, but you can still end up at the leaf of the category with a couple hundred things to list, which is done via a pagination system (lets say 50 per page). Now, the people who own the things pay to have their things on the site. Lets say there are three levels of option for listing: gold, silver, bronze. The default order is gold things, silver things then bronze things. Within each level, the things are listed alphabetically (again this is just the default). Now if 100 things in one category have a gold level listing, those in the second half of the alphabet will be on page two by default. They don't like this and they question why they are paying for gold at all. My client would like to present things in a more random way to give all gold level things a chance to be on the first page of results in a fairer way than just what they happen to be named. Right that's the back story. It's more complex than that, but the above is a nice and simple abstraction. Problems: There are numerous problems to randomised listings: you can't actually truly randomise results otherwise pagination breaks. Server-side caching/denationalisation is affected as there is no longer "one listing" but "many random listings". Discussing a link with a friend over IM or email and saying things like "the third one down looks best" is obviously broken too, but this is something my client accepts and can live with. Also, if the intention is to reassure the thing owners that their listing will appear further up the listings at times, the fact that a simple refresh will not reorder things for a given session will make that point harder to get across to less web-educated clients (that's a nice way of saying it!). Caching proxies and other similar things after the webserver will also come into play. So to me there are only really two options: 1. Random-per user (or session): Each user session gets some kind of randomisation key and a fresh set of random numbers is generated for each thing. They can then be reliably "randomised" for a given user. The fact that each user has their own unique randomisation is good, but it doesn't help things like server side full page caching and thus more "work" needs to be done to support this approach. 2. Random-bank + user/session assignment: So with this approach we have a simple table of numbers. First column is an id and is sequential form 1 to . This table has lots of columns: say 32. These columns will store a random number. Once generated, this table acts as an orderer. It can be joined into our thing lookup query and the results can be ordered by one of the columns. Which column to use for ordering is picked by a cookie stored on the users machine. That way the user will always get the same random result, even if they revisit the site some time later (users not accepting cookies is not a huge deal, but I would suggest the "pick a random column" algorithm (used to set the cookie initially) is actually based on source IP address. That way even cookieless folks should get a consistent listing unless their change their IP). I'm obviously leaning towards the second approach. If I have 32 "pre-randomised" columns, this would get a pretty good end result I think. If we re-randomise periodically (i.e. once a week or month) then this can be extended further (or simply more columns can be added). I think it's the lowest impact but there are sill some concerns: Server side caching is still problematic. Instead of storing one page per "result" I now have to store 32. This will lower significantly the cache hits and perhaps make full result caching somewhat redundant. If that is the case, then so be it, but load will have to be managed. So my question for the lazy-web: Are there any other approaches I've missed? Is there some cunning, cleverness that eludes me? Are there any problems with the above approach? Would a caching proxy ultimately cause problems for some users (i.e. storing a cache for page 1 and page 2 of the same listing but with different randomisations)? And if so can this be mitigated? Thanks for reading and any insights you may have!

Just for reference: 1. The Package Manager GUI will indeed sort it all out for you. 2. The Package Manager GUI is just a frontend for urpmi. All the dependency tracking etc. is in urpmi.

If you have any doubt and want to be more specific, just install task-lamp-php. All of these are listed in the Package Manager GUI. Just pick "Meta Packages" and then look under System->Servers (or just search for the name: staring the GUI and typing "lamp" into the search box is really all that's needed). 4. Yes PHP can be installed as cgi, apache module or command line. There is no such thing as "installing php" - you install which system you want: command line (php-cli), apache module (apache-mod_php) or cgi (php-cgi).

I found this problem,because the software transplantation.In the 64-bit
systems,the array seems to always have limited capacity. I'm not sure that is
php version problem or need other configurations.
I suspect it's just different configuration.
That said, I've generally found that 64bit versions of PHP need more
memory than their 32bit equivs, so perhaps all you need to do is
something like:
ini_set('memory_limit', '50M');
and you'll be fine.

[PHP] Logical reason for strtotime('east') and strtotime('west') returning valid results?
Hi,
Long time no speak!
As part of a quick filter I'm writing I try to interpret free text
strings as dates and textual data.
Sometimes, this goes wrong.
For example, I discovered that some words (or strings beginning with
those words) will return false positives:
e.g.:
[co...@jimmy Search (working)]$ php -r 'var_dump(strtotime("east"));'
int(1270514111)
[co...@jimmy Search (working)]$ php -r 'var_dump(strtotime("west"));'
int(1270488914)
[co...@jimmy Search (working)]$ php -r 'var_dump(strtotime("now"));'
int(1270488928)
The last one is valid! But the other two appear to do much the same thing...
Can anyone think of why this would be valid results before I report this
to the relevant authorities?

I used to think like that too, but I've relatively recently changed my position. While it's not as extreme an example, I used to keep data in the database *after* I had processed it with htmlspecialchars() (not quite the same as strip_tags, but the principle is the same). The issue I had was that over time, I've found the need to output to other formats - e.g. spread sheets, plain text emails, PDFs etc. in which case this pre-encoded format is a pain and I have to call html_entity_decode() to reverse the htmlspecialchars() I did in the first place. This is a royal pain in the bum and it's really ugly in the code, remembering what format the data is in in order to process it appropriately at the right points. Nowadays I work rather differently and always escape at the point of output (this does not exclude filtering at the point of input too, but I do not keep things encoded any longer - I keep it raw). Any half way decently designed caching layer will prevent any major impact from escaping at the point of output anyway. Now you could argue that encoding at the save point and reversing the encoding when needed is still a better approach and I wont argue too heavily, but for the sake of my sanity I'm much happier working the way I do now. The view layers are very clearly escaping everything that needs escaping and no logic for the "is it or is it not already escaped" leaks into this layer. (I appreciate strip tags and htmlspecialchars are not the same and my general usage may not apply to a pure striptags usage). > at any rate, strip_tags() doesn't belong in an 'anti-sql-injection' routine as > it has nothing to do with sql injection at all. Indeed, it's more about XSS and CSRF rather than SQL injection.

You are probably not privileged enough (as a user) to do this. You
likely want to pass it through "sudo" first.
e.g. sudo ./apachectl graceful.
You should be prompted for you *user* password. If you user is allowed
to administer the machine, you should become root temporarily and run
the command.
If you run several sudo commands in relatively quick succession, you
wont have to type your password in again.

Forgive the perhaps silly question but why are you requiring to use
constants here.
I appreciate the desire to use Reflection but why not just define a
method that must be implemented in the interface?
interface SetKillSwitch {
public function getKillDate();
public function getKillNotes();
}
By virtue of something impementing the interface, you know the methods
will exist.
If you want to make implmentation of classes easier, then define and
abstract class with an appropriate constructor and implementation:
abstract class SetKillSwitchAbstract {
private $_killDate;
private $_killNotes;
protected function __construct($killDate, $killNotes)
{
$this->_killDate = $killDate;
$this->_killNotes = $killNotes;
}
public function getKillDate()
{
return $this->_killDate;
}
public function getKillNotes()
{
return $this->_killNotes;
}
}
You can either put your "implements SetKillSwitch" in this class or the
derived classes depending on other methods you want to provide in the
base class.
I don't see why constants specifically are needed here. Rather than
using reflection you can just use instanceof or similar to tell if a
given object implements the interface or simply use the interface name
as a type specifier on an argument to another function/method etc.

This sounds very much like you are mixing and matching different sources of RPMs. Linux distributions are not like Windows machines where you can just install any given application, they are an integrated set of interdependant packages. It is not at all recommended (read: a very bad idea) to install e.g. RPMs build for one OS version (e.g. RHEL 5.x) on an older version (e.g. RHEL 4.x). Doing so can cause numerous problems due to compiler changes/optimisations and small ABI breakages that are incompatible with the dynamic libraries used etc. Even if you do pull in all the dependancies when installing a RHEL5 version of PHP on RHEL4 (just an example), it will not necessarily work for the above reasons. Similarly, if you do run into problems you will not get any support (paid or otherwise) for such a setup. So please don't undertake this upgrade without fully appreciating what is going on. If you really want to install the RHEL5 version on RHEL4 (again just a random example of a distro), you should download the source rpms and rebuild them on RHEL4. You may have to rebuild quite a few dependant packages to get a fully working system.

'Twas brillig, and Manuel Aude at 23/06/09 08:38 did gyre and gimble: I'm giving a PHP course next semester (3 hours all saturdays for 22 weeks) and I just realized that PHP 5.3 is coming very soon (2 days now!). So, my plans of teaching PHP 5.2 are starting to change, and I think it's a good idea to teach them 5.3 already. While the majority of the students use Windows, I'm aware that a vast amount will be using Ubuntu/Debian (and some use Gentoo, Fedora and Arch) distributions of Linux, so I'm hoping there won't be too many problems on installation. I don't want to waste the entire first class fixing installation problems, because that kills the student's motivation. The course starts on August, but I'm preparing it during the last two weeks of July. You think that installation packages will be bulletproof by then? Or should I just teach 5.2 and wait for another semester before starting on 5.3? I mean, most hosts will remain with PHP 5.2 for the rest of the year, so I'm a bit confused on what I should do. Well I'd imagine the vast majority of your course will be covering the basic principles of PHP coding, techniques, GPP, frameworks etc. Generally most people will want to use a Framework, (Zend, Cake, etc.) which will take a while to adopt PHP 5.3 anyway (some still support PHP4 so what hope is there to use features of PHP5.3 anyway soon!) so I'd suggest teaching the basics on a PHP5.x system and then perhaps spend two or three sessions at the end covering the newer stuff from PHP 5.3. That's probably the way I'd go, and you can give people some prior warning to try and get a PHP 5.3 install up and running for the x'th week of the course.

[PHP] Re: Periodic Actions in PHP?
'Twas brillig, and Parham Doustdar at 13/06/09 09:42 did gyre and gimble: Hi there, I'm going to create a small chat script with PHP. The messages you want others to see will be added to a flat file (I.E. TXT file), and read and displayed by PHP. However, I want this reading and displaying to be periodic. This means that I want PHP to check the file for new lines every,say, fifteen seconds. How may I do that? I have been unable to find any function that acts like a timer. For handling periodic tasks in a web environement, I use a little persistent object (stored using APC) that has it's "process()" method called on every request. Internally it knows when it was last run and will actually only do work in it's process() method if it's not been called for a while. When this work is done, the user's request is obviously slowed down slightly, but not in a noticeable way. If you don't need something this self contained, then a normal cron job is needed. All that asside, I'm not sure you're asking the right question. If you've got a chat system, then the client side is presumable a web server. You can't really push information from the server side to the client, so you really need to pull it from the client side. Usually you'd have a javascript timeout that submits an ajax request to the server and displays any new messages to the user. In this case, PHP doesn't need to be timed, the client is pulling periodically so it's the client that sets the timer.

please help me...
I happen to not agree completely with the post, because it seems to
propose the use of things like "continue", "break" and "return" within
control structures (the latter as opposed to at the end of a function,
exclusively). Very bad practice in my opinion. Think of everything that
has ever been said of "goto", it's just as bad for structured programming.
(however the use of "break" in "switch .. case" statements is an
unfortunate necessity in PHP)
And in C. And there is nothing inherently *wrong* with goto. Sure it
*can* lead to less readable code, but by going out of your way to avoid
it's use can lead to equally unreadable code.
Just like the break statement which is a fundamental part of switch
statements but also very useful to get out of infinite loops (our old
favourite for (;;)) etc.
For this reason early return should not be completely discounted out of
hand as a "bad programming practice" as this is simply not true.
If early return is ugly for you then you can never use other constructs
in OOP like exceptions. These interrupt the code flow execution in
interesting ways too (and the same for the whole break and continue
statements in controlled loops)
So personally I like early return. I use it mostly to cut down brace and
indentation churn. I try to keep code into 80 cols and if 40 of them are
used up with indents that doesn't leave much room for the actual code!
I think with any programming structure, you just have to make sure your
code is clear, obvious and readable. If you've got a function that
sprawls four+ screenfulls and has returns littered throughout it, then
this is obviously not very readable. Re-factoring should solve this, but
just re-factoring to avoid early return will probably do very little to
improve it's overall readability IMO.
In many cases early return can improve readability.
e.g. consider
$rv = false;
if ($condition)
{
// ... several pages of code.
}
return $rv;
When reading this function, I *could* be interested in what happens if
the condition is not met. In this scenario I have to scroll down and
track where the brace is closed and then follow the code on from there.
Now consider this:
if (!$condition)
return false;
$rv = false;
// ... several pages of code.
return $rv;
With this code, considering I'm interested in what happens if the
condition is not met, I can satisfy my curiosity immediately without
looking further.
In both cases if I was interested in the opposite, it's the same amount
of tracking to look through the code itself.
As with everything in programming style, this mostly comes down to
personal preference. So just stick with a style you like :)
People get almost as emotive about this topic as top-posting on mailing
lists :) I'm not overly fussed. I know what i like and it doesn't offend
anyone in public :p

You'll want to use the Singleton design pattern here.

That's well and good if the thing you want a single copy of is an object. The
way objects pass in PHP 5 makes singletons easy. But I actually just
developed a system for PHP 5.2 that includes a class that deliberately allows
a caller to reach in and grab an internal array-based data structure for
special cases.
class Foo {
protected $internalConfig = array(...);
public function &getConfig() {
return $this->internalConfig;
}
}
$foo = new Foo();
...
$config = &$foo->getConfig();
// Do stuff to $config that wouldn't make sense to do via methods.
So do I understand the OP correctly that is going to break with PHP 6 now? I
certainly hope not, as that would be incredibly short sighted and stupid.
There are plenty of use cases for returning by reference besides making PHP 4
objects behave correctly.
Use ArrayObject rather than just array. e.g.
class Foo {
protected $internalConfig;
public function __construct() {
$this->internalConfig = new ArrayObject(...);
}
public function getConfig() {
return $this->internalConfig;
}
}

Let's say you're config object is a class.
Something like this should work very nicely.
class My_Config
{
private function __construct()
{
// Whatever you need to do to load the config
}
public static function getInstance()
{
static $instance = null;
if (null === $instance)
$instance = new self();
return $instance;
}
}
Then in your code whenever you want to get your config object you would
call:
$config = My_Config::getInstance();
You'll only every get one object created due to the private constructor
and which enforces the use of the getInstance() method.
This is a very common design pattern, and is ideally suited to this use
case.

Questions:
1. Do we really need the statements - $result1 = mysql_query($sql1,
$db); ? Why? What purpose do they serve?
These statements send your SQL to the server. Without them you are just
assigning and SQL command to a variable so they are really rather
important :p
2. How can one use "mysql_insert_id()" to insert data into multiple
tables? Why would you need to insert an id - especially since there are
only 2 fields in the pulblishers table (above) - id (auto-increment) and
publishers? As I ;understand it, when the id field is auto-increment, a
simple
INSERT INTO publishers (publisher) VALUES ('$publisherIN') works fine (but not
above)
Can somebody suggest anything? TIA
Short answer, you can't! It's not what it's for!
You have to do your insert first (with mysql_query() as you did above),
and then call $my_generated_id = mysql_insert_id(); This will fill the
variable $my_generated_id with the value of the auto_increment field in
your table from the last call to mysql_query with an INSERT statement.
Also, you are possibly running risks above if you do not properly escape
your variables:
e.g. You have:
$sql1 = "INSERT INTO authors (first_name, last_name) VALUES
('$first_nameIN', '$last_nameIN')";
Your examples do not show where the values came from but if it's
directly from a form post or similar, if I put the value:
'blah','blah'); DELETE FROM authors;
The query generated could be:
INSERT INTO authors(firstname,lastname) VALUES ('blah','blah'); DELETE
FROM authors;.
Obviously this is a massive security risk and is generally referred to
as "SQL Injection Attacks".
You should look into using the function mysql_real_escape_string() to
escape all your inputs.

Perhaps where we should go is that even if the URL is https:// there is no UI change in the browser. Only if the cert is trusted by a CA should the browser UI change to indicate this in some way, with HV certs being explicitly indicated as such to increase the "trust" aspect.

Getting a certificate is nothing if the system is not backed up by a trust system. If a CA was setup that gave out certificates willy nilly to all and sundry, then this element of trust is lost. For $1 you're not likely to be able to afford to do much in the way of vetting or confirmation that said person is who they say they are. If browsers trusted that CA and an unscrupulous individual manages to get a secure certificate for a domain they do not own they could then use some form of DNS hijacking (e.g. via an open wireless network or similar) to perform some pretty convincing phishing scams.

I would expect that if I turn on output buffering, echo something,

In the following code, I would not expect to see the , but I do.
You should not see this!';
throw new Exception('This should be the first output.');
exit( 'Contents: ' . ob_get_clean());

catch (Exception $ex) {
exit('Exception:' . $ex->getMessage());
}
I'm exercising that code on PHP 5.2.4 and 5.2.8.
Does anybody know why throwing an exception seems to override
ob_start(), flushing the buffered output? Is there a workaround?
This is intended behaviour and just represents the natural application
flow. Exception handling in PHP does not have any concept of "output
buffering" and operates in a generic way. You start output buffering but
you don't explicitly turn it of or clean the contents and thus, when the
script ends (inside your catch block), it will be automatically flushed
(displayed).
If you don't want any output, make sure your catch block first calls
ob_end_clean() before it exits.

I don't mean to state the very obvious but of course frameworks will be slower than a simpler and less flexible/powerful/maintainable solution. That's like buying an F1 car for your daily commute to work then complaining about the MPGs you get! Frameworks are not about running faster, they are about implementing faster and more efficiently, using a standard technique that allows other developers to take over from you later with minimal hand over, it's about being able to take on new staff without having to train them in all your specific code etc. One of the things these speed tests totally fail to take into consideration is that any sensibly written application will have a caching structure at it's core and will utilise it *heavily*. When an application is written with a good caching policy/infrastructure, the performance as a whole goes up by orders of magnitude. Some performance shootouts don't even employ opcode caches which is just insane in any kind of sensible hosting environment. In short, don't believe the hype and use a little bit of logic and common sense to make comparisons as to which approach is "better" (remember "better" != "raw performance") for you.

While it's true that having a bunch of worthless data doesn't accomplish anything and slows the process of dealing with it. But, technology in access times and storage capabilities are getting to the point of making the decision to keep/delete worthless data moot. As such, I think the need for FK deletions will become less and perhaps disappear from the language. For some reason, I look upon deletions in similar light as renumbering a table's index after deletion of a record -- like "what's the point?" I'm just rambling -- thanks again for your insight. Rambling is good... I'll continue! With data retention and data protection laws (something that can vary around the world making life for web-based providers like ourselves even more complex), I think it is increasingly important that information about a given person can be scrubbed very easily. Keeping the data may be cheap from a storage/access perspective, but complying with laws and regulations can be wearisome and time consuming. If you FKs are fully up-to-date and have proper cascading you can be sure that a simple: DELETE FROM users WHERE user_id=123; really will delete all the information you store about that individual. You just have to look at the hullabaloo over the "deactivated" Facebook accounts etc. to realise that hiding or disabling data is not enough in many cases. Food for thought!

'Twas brillig, and Ashley Sheridan at 03/12/08 08:15 did gyre and gimble: Whatever you do, don't have a separate page for "print view". This is one of those things that some bright spark thought to do on a site at work, and the site in question was already a couple hundred HTML pages, so he effectively doubled that figure. It makes your work harder in the long run if you need to update it at any time, and with the media="print" attribute set for the extra stylesheet, it's automatically selected anyways. While I don't want to disagree with the print media option (it's my preferred route), depending on your application/use case etc, having a separate print layout could make sense. Say you have a content management system that displays an "entry" over several small pages. If you want to print out details of that "entry" it may make sense to combine the salient details from all the mini-pages into one "printable" page. If your application is designed well, then this approach certainly doesn't double your number of "pages" (from a maintenance perspective). If you have a 1000 "entries" each with 5 mini-pages and you add a print version you are changing the number from 5 to 6, not 5000 to 6000.

What are the pros and cons of doing this? I figured it would help out with disk I/O and overall performance because MemCache would be much faster than the IDE drive, and I update/reference the $_SESSION data very often.

From your original context it wasn't clear whether you wanted to cache the dom document *object* that represents the xslt or the output of the transfer after it is applied. As I explained, (and I think I'm still correct in this), storing the object would be kinda pointless as it would have to be serialized to string form and then re-parsed on wakeup.

If you just want to cache the XSLT itself (e.g. loaded into a DOM document object) then there is little point as you would have to serialize and deserialize the dom document objects before storing them (via extending the class and adding __sleep() and __wakeup() methods) as I am pretty sure Dom Document doesn't do this automatically (last I checked which was admittedly a while ago!).

Correct, but you're then breaking one of the rules of the singleton

private and call the parent's constructor:

public function __construct($foo)
{
$this->foo = $foo;
}
public function getFoo()

I don't really get what you're trying to say here.
All I'm saying is that empty(), as a language construct, should be more
efficient than the resulting function call overhead when using
array_key_exists().
As I highlighted in my previous example, the only way to test of an
array has an index which is set to null is to use the array_key_exists()
function as both isset() (also a language construct) and empty() will
not be able to tell you this.
So your example above (which sets an array index to null) is the only
way to do what you want to do (the switch() is overkill for an if/else
scenario but that's beside the point).
All I was saying was that for an array index value that is set to a
known true/false value, or not set at all, using !empty() to test for
when the value is true is the most efficient way.
Consider the following two attached test cases to check for a true
value, two indexes deep in the array. One uses two calls to
array_key_exits and then a comparison, the other uses !empty(). They are
functionally equivalent but the results speak for themselves:

Has anybody got any ideas?? Is there any (free) software out there capable of this?? If anybody else wishes to contribute to this very young project, I am open to ideas ([EMAIL PROTECTED]). Hosting is sorted and I own BarcodeDB.com and .co.uk I personally perfer the "API Key" approach where a user will generate an API key that is linked to their user account and can be embedded into remote applications etc. A simple interface to generate and revoke API keys should be available somewhere within your application. You can then use this API key in your requests as you see fit. An API key would typically take the form of a UUID (try SELECT UUID(); in mysql) It's obviously open to snooping and other such nefarious acts and if you want to do a more stringent test you should use some form of digest authentication which will require two way communication. If this is too complex, running your API over SSL should cut down on the snooping risk and grabbing the API keys. The good thing about using API keys like this is you can setup various things in your app as you see fit, like a TTL (time to live) or specific (i.e. restricted) permissions assigned to different API keys generated by a user.

You can probably short-circuit some of that - for example if
$_SESSION['userInfo']['loggedIn'] is only ever set to TRUE (and is not set
otherwise) then you might find that
if (isset($_SESSION['userInfo']['loggedin'])) {
As I mentioned elsewhere on this thread, !empty(..) is a better way of
doing this as it works in the case when the value is set to FALSE too.

Hey Colin,
Does the ! reverse the empty in this case? such as !empty = not empty?
Yes. That's what the ! always does. It's the "not" operator in PHP (and
most languages):

You'd first need to check that the key 'userInfo' existed in the
$_SESSION array too.
Personally, I very rarely see the point in using array_key_exists...
It's a function call and has overhead where as isset() and empty() are
language constructs and (I would hope) are much more efficient (although
I've not done any benchmarks).
There are cases where you may want to use array_key_exists where isset()
and empty() would fail, e.g.
$arr['foo'] = null;
isset($arr['foo']) == false
!empty($arr['foo']) == false
array_key_exists('foo', $arr) == true

Good morning everyone!
I think I might be having a "to early in the morning/not enough
caffeine" moment... But I am down to 1 error on my timecard application
that I would like to clean up. It's a small undefined index error, and
the program works jsut fine the way it is, but why leave an error if you
don't need to? :)
Here is the error:
[Tue Oct 14 08:19:47 2008] [error] PHP Notice: Undefined index:
userInfo in
/Volumes/RAIDer/webserver/Documents/dev/stimecard/inc/function/authentication.func.php
on line 22
and here is the relevant code:
==> Line 22if($_SESSION['userInfo']['loggedin'] == TRUE) {
if(isset($_SESSION['userInfo']['loggedin']) &&
$_SESSION['userInfo']['loggedin'] == TRUE) {
Or, seeing as I'm a stickler for compact code:
if(!empty($_SESSION['userInfo']['loggedin'])) {
empty() is like isset() but tests for all sorts of "empty" cases ('',
false, null and 0 are all considered, "empty").

I've not seen your name here before and I've posted and contributed quite a bit over the last few years so have a right to the odd indulgence on what is generally a nice mix of technical advice, assistance and discussion with a strong social side to it. While I'm not sure that Alex meant to post to the list, I thought it would be worth pointing out to those that were intrigued by it what it actually was. I think I was doing a service here. Also the TED.com website is an interesting resource for people involved in technical industries and while it's not directly related to PHP, many people interested in PHP would be interested in it and I felt it was worth pointing that out.
