[PHP] convert Object to Array

測試webservice發現回傳回來的值為Object，如下：
[schema] => stdClass Object
        (
            [element] => stdClass Object
                (
                    [complexType] => stdClass Object
                        (
                            [choice] => stdClass Object
                                (
                                    [element] => stdClass Object
                                        (
                                            [complexType] => stdClass Object
                                                (
                                                    [sequence] => Array
                                                        (
                                                            [a] => 0
                                                            [b] => 1
                                                            => 2
                                                            [d] => 3
                                                            [e] => 4                                                            
                                                        )
                                                )
                                        )
                                )
                        )
                )
        )
我一時之間也不知道要如何是好，上傳搜尋一下，發現一個不錯的function，可以將Object 轉換成 Array，我使用後沒什麼問題提供給大家參考

function std_class_object_to_array($stdclassobject)
{
   $_array = is_object($stdclassobject) ? get_object_vars($stdclassobject) : stdclassobject;
foreach ($_array as $key => $value) {
$value = (is_array($value) || is_object($value)) ? std_class_object_to_array($value) : $value;
$array[$key] = $value;
}
    return $array;
}

使用方法如下：

$test=std_class_object_to_array($schema);
$a=trim($test[element][complexType][choice][element][complexType][sequence]['a']);

這樣就可以取出a的值了
