为什么Eclipse反对`static :: $ var`？

Question

我在PHP类中有以下静态函数:

static function __callStatic($method,$args){
    $called=NULL;
    if(empty(static::$collection)) static::slurp();
    if(method_exists(static::$objtype,$method)){
        foreach(static::$collection as $obj){
            $called[]= call_user_func_array(array($obj, $method), $args);
        }
    } else if (property_exists(static::$objtype,$method)){ //$method isn't a method, it's a property
        foreach(static::$collection as $obj){
            $called[]= $obj->$method;
        }
    } else if($method=='collection'){
        $called=static::$collection;
    } else {
        throw new ZException("$method does not exist");
    }
    return $called;
}

静态变量都已定义但可能未设置.代码看起来像我想要的那样,并且不会抛出任何级别的错误.但是我的Eclipse(Helios)PDT的新安装已将每个实例标记static::$var为"意外的静态"错误.如果我更换static::$var与self::$varEclipse的错误去离开-但随后的代码不起作用.

我如何说服Eclipse这些不是错误？

PHP 5.3引入了Late Static Binding.检查Window> Preferences> PHP> Executables and Interpreter以确保Eclipse使用PHP 5.3.
