PHP 调用对象方法问题

Call to a member function get_type() on string in

<code>public function process($aData, &amp;$aResult, $aConfig)
{
    var_dump($this-&gt;cart_object_apps);die;//数组里面是3个对象

    foreach ($this-&gt;cart_object_apps as $key =&gt; $object) 
    {
        $type_name = $object-&gt;get_type();//为什么调用此方法会包上述错误

        //$aResult['object'][$type_name] = $object-&gt;getAll(true,$aData);




    }
</code>

回复内容：

<code>public function process($aData, &amp;$aResult, $aConfig)
{
    var_dump($this-&gt;cart_object_apps);die;//数组里面是3个对象

    foreach ($this-&gt;cart_object_apps as $key =&gt; $object) 
    {
        $type_name = $object-&gt;get_type();//为什么调用此方法会包上述错误

        //$aResult['object'][$type_name] = $object-&gt;getAll(true,$aData);




    }
</code>

说明这个$object没有get_type方法。
我猜你是想调用gettype来获取类型吧？请参考这里:http://php.net/manual/zh/function.gettype.php
