如何刪除一維數組的key，不想用兩個foreach迴圈出來。

1.想把二維數組變成一維，刪除一維KEY的arr值，有函數嗎？
2.數組代碼：

 stdClass Object(    [arr] => stdClass Object        (            [0] => stdClass Object                (                    [id] => 14                    [cid] => 221                    [title] => 深圳市軌道交通網路運營控制中心室內精裝、玻璃幕牆工程                    [source] =>                     [count] => 0                    [img] => http://upload.55.cn/source/44/201606/50457731d4be5e5c1.jpg                    [info] =>                     [fee] => 0                    [url] => /product/detail/14.html                    [cate_name] => 裝修工程                )            [1] => stdClass Object                (                    [id] => 12                    [cid] => 220                    [title] => 南充嘉陵江1000T級泊位都京碼頭                    [source] =>                     [count] => 0                    [img] => http://upload.55.cn/source/44/201606/55557731d15a3aa42.jpg                    [info] =>                     [fee] => 0                    [url] => /product/detail/12.html                    [cate_name] => 水利電力工程                )

如何把arr刪除？否則用兩個foreach迴圈出來不優雅。。

$resultArr = $targetArr['arr'];

是我理解錯了？

是對象應該是 $result->arr 的

把對象轉換成數組
$a = $result['arr'];
