如何自动加载类文件!
现在用的是autoload(代码如下:),还有别的方法能自动加载类文件吗?除了include(具体文件路径)

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->function __autoload($className){if(file_exists('model/'.$className.'.class.php')){include_once('model/'.$className.'.class.php');}if(file_exists('Controller/'.$className.'.class.php')){include_once('Controller/'.$className.'.class.php');}$prefix=$GLOBALS['groupName']=='main'?'':'../';if(file_exists($prefix.'core/'.$className.'.class.php')){include_once($prefix.'core/'.$className.'.class.php');}if(file_exists($prefix.'core/Smarty-3.1.6/'.$className.'.class.php')){include_once($prefix.'core/Smarty-3.1.6/'.$className.'.class.php');}if(file_exists($prefix.'core/Smarty-3.1.6/sysplugins/'.$className.'.php')){include_once($prefix.'core/Smarty-3.1.6/sysplugins/'.$className.'.php');}}


------解决方案--------------------
你是不是嫌这比较麻烦?
其实是因为你类文件放的地方比较多,而且你上面应该是用if else if或switch...case。语句。
如果你嫌麻烦的话可以用个数组来保存所有的路径比如。
PHP code
$arr = array('classPath1','classPath2','classPath3');foreach($arr as $v){  $new_path = $v.$className.'.php';  if(file_exists($new_path)){    include_once($new_path);    break;  }}<div class="clear">
                 
              
              
        
            </div>
