spl_autoload_register

(PHP 5 >= 5.1.2)

spl_autoload_register — Register given function as __autoload() implementation

Description

bool spl_autoload_register ([ callback $autoload_function ] )

Register a function with the spl provided __autoload stack. If the stack is not yet activated it will be activated.

If your code has an existing __autoload function then this function must be explicitly registered on the __autoload stack. This is because spl_autoload_register() will effectively replace the engine cache for the __autoload function by either spl_autoload() or spl_autoload_call().

Parameters

autoload_function

The autoload function being registered. If no parameter is provided, then the default implementation of spl_autoload() will be registered.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 spl_autoload_register() example

<?php

namespace Foobar;

class Foo {
    static public function test($name) {
        print '[['. $name .']]';
    }
}

spl_autoload_register(__NAMESPACE__ .'::Foo::test'); // As of PHP 5.3.0

new InexistentClass;

?>

The above example will output something similar to:

[[Foobar::InexistentClass]]
Fatal error: Class 'Foobar::InexistentClass' not found in ...
