PHP的autoload如何避免加载内部类?
使用PHP的autoload时,为什么连PHP内部类也会被加载,比如使用PDO,autoload会尝试加载PDO.php。这种情况要如何避免呢?
<code>function __autoload($className){ require_once APP_PATH.'Controller/'.$className.'.php'; }</code>

你确定在使用PDO这个类的时候类名正确吗?在namesapce
下使用PDO
需要使用use
或者写成\POD
的形式。另外确保你的PDO扩展已经按照并正常载入。
内部类会在MINIT
时载入,优先于请求,出现这种情况要么是内部类的类名没写对,要么是没有加载这个内部类的扩展。
如果使用命名空间,需要声明use PDO;
或者创建对象时用new \PDO
