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

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');
}

}

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>
Copy after login
