PHP將XML轉數組過程詳解

得到一個xml型的對象：

$resp = $this->c->execute($req, $sessionKey);//獲得xml對象$items=$resp->items;

那麼讀取對象的值，就用$items->item，或者$items->item->price，如此操作很不方便，不符合php運算元組的習慣。

php提供了array方法將對象轉換成數組，只要把你要轉換數組的對象前面加上（array）就行了。

比如將$items->item（有很多item的對象）轉換成數組：

foreach ($items->item as $item){         $goods[]=(array)$item;}

$goods就是一個php數組了。
轉換前：

SimpleXMLElement Object(    [cid] => 50003793    [modified] => 2013-04-18 17:16:25    [nick] => qq307819623    [price] => 200.00    [title] => Nokia N97全新行貨)SimpleXMLElement Object(    [cid] => 50024921    [modified] => 2013-04-18 16:58:06    [nick] => qq307819623    [pic_url] =>pic.jpg    [price] => 888888.00    [title] => 劉俊仲)SimpleXMLElement Object(    [cid] => 1512    [modified] => 2013-04-18 16:56:46    [nick] => qq307819623    [pic_url] => item_pic.jpg    [price] => 323232.00    [title] => 二手你好)SimpleXMLElement Object(    [cid] => 50012166    [modified] => 2013-04-18 15:10:07    [nick] => qq307819623    [pic_url] =>0-item_pic.jpg    [price] => 32.00    [title] => 放大率拉德斯基分拉沙德瘋了似的看法拉斯法)

轉換後：

Array(    [0] => Array        (            [cid] => 50003793            [modified] => 2013-04-18 17:16:25            [nick] => qq307819623            [price] => 200.00            [title] => Nokia N97全新行貨        )    [1] => Array        (            [cid] => 50024921            [modified] => 2013-04-18 16:58:06            [nick] => qq307819623            [pic_url] => pic.jpg            [price] => 888888.00            [title] => 劉俊仲        )    [2] => Array        (            [cid] => 1512            [modified] => 2013-04-18 16:56:46            [nick] => qq307819623            [pic_url] =>item_pic.jpg            [price] => 323232.00            [title] => 二手你好        )    [3] => Array        (            [cid] => 50012166            [modified] => 2013-04-18 15:10:07            [nick] => qq307819623            [pic_url] => 0-item_pic.jpg            [price] => 32.00            [title] => 放大率拉德斯基分拉沙德瘋了似的看法拉斯法        )
