PHP將XML轉數組過程詳解

得到一個xml型的物件：

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

那麼讀取物件的值，就用$items->item，或是$items->item->price，如此操作很不方便，不符合php操作陣列的習慣。

php提供了array方法將物件轉換成數組，只要把你要轉換數組的物件前面加上（array）就行了。

例如將$items->item（有很多item的物件）轉換成陣列：

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

$goods就是一個php陣列了。
轉換前：

SimpleXMLElement Object
(
    [cid] => 50003793
    [modified] => 2013-04-18 17:16:25
    [nick] => qq307819623
    [price] => 200.00
    [title] => Nokia N97全新行货
)

    [nick] => qq307819623
    [pic_url] =>pic.jpg
    [price] => 888888.00

)

    [nick] => qq307819623
    [pic_url] => item_pic.jpg

)
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疯了似的看法拉斯法
)

轉換後：

Array
(
    [0] => Array
        (
            [cid] => 50003793
            [modified] => 2013-04-18 17:16:25
            [nick] => qq307819623
            [price] => 200.00
            [title] => Nokia N97全新行货
        )

    [1] => Array
        (
            [cid] => 50024921
            [modified] => 2013-04-18 16:58:06
            [nick] => qq307819623
            [pic_url] => pic.jpg
            [price] => 888888.00
            [title] => 刘俊仲
        )

    [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疯了似的看法拉斯法
        )
