介绍PHP5的给类型函数应用

<?php
// Declare an autoload function and register it using SPL
function __autoload($classname) {
    @require_once "class-{$classname}.php";
}

// Now create another one.
function another_class_autoload($classname) {
    @require_once "obj-{$classname}.php";
}

// Check  __autoload() has been declared before registering our function
if (function_exists('__autoload')) {
    spl_autoload_register('__autoload');
}

// Now register our own function.
spl_autoload_register('another_class_autoload');

// Instantiate an object of class 'cd'.  
//   This will make it try to load the file: class-cd.php or obj-cd.php
$mydisk = new cd();
?>
