[RESOLVED] using autoload to call required class files

[Dopple]

Hi there. According to http://uk.php.net/__autoload Ithe code below should call class files as requested. This doesn't seem to work if I am calling the classes from within a method. See method2 in example for instance of this.

<?php
function __autoload($class_name) {
    require_once $class_name . '.php';
}

function method2() {
    $obj  = new MyClass1();
    $obj2 = new MyClass2(); 
}

$obj  = new MyClass1();
$obj2 = new MyClass2(); 
?>

When I access my actual script i get
Fatal error: Class 'User' not found in /home/www/gramac4.freeserverhost.com/Incident.php on line 32

Sorry, it's because I had __autoload() within a class. I moved it outwith the class and it's ok now.

LOL: I made that same mistake when I first read about it. It looks like the other "magic method" names, and I somehow assumed it was supposed to be in a class. Drove me crazy for awhile until the lightbulb went on over my head the third or fourth time I read over it and a couple other web pages.

One question I do have is this. If you have this in your class file, and then call another class which has it, it says you cannot redefine __autoload(). What's the best way of dealing with this? Just not have it in all my class files?

I suppose it depends on your overall application design, but if there's one configuration or controller class that is always used to start off your pages, that might be a good place. If there is more that one place you need to put it, you could wrap it in a if(!function_exists('__autoload')) { . . . } block.

Thanks. I tried just having it in the index.php page which is calling everything through index.php?action=etc blah blah blah but it didn't work. It doesn't matter. I'm just gonna plough through this then release my code for review. It's basically a web based helpdesk application that I'm gonna put on sourceforge so I reckon any major flaws in my programming should come to light if people start looking at the code.
Thanks again
