MVC  类继承 自动加载

最近在学习MVC开发模式。现在遇到个问题,就是自动加载类的问题。比如说我建一个控制器,AdminAction.php.然后我想让他继承同目录下的FirstAction.php.而且我想直接Class AdminAction extends FirstAction.不想先Include ‘FirstAction.php'.能不能用__autoload来实现啊。为甚ThinkPHP里面就是可以直接新建一个Action就直接写继承他的基类Action而不用引入啊。求大神帮忙开导下

<?php // PHP5 Used __autoload function $obj_A = new clsA(); // in "cls" directory! $obj_B = new clsB(); // in "cls/cls" directory! function __autoload($className){ if(strtolowwer($className) == "clsb"){ require_once "cls/cls/$className.php"; }else{ include_once "cls/$className.php"; } } ?> 
Copy after login

// ./myClass.php<?phpclass myClass {    public function __construct() {        echo "myClass init'ed successfuly!!!";    }}?>// ./index.php<?php// we've writen this code where we needfunction __autoload($classname) {    $filename = "./". $classname .".php";    include_once($filename);}// we've called a class ***$obj = new myClass();?>
Copy after login

一般好像是在使用多个类才这样使
