1.想把二维数组变成一维，删除一维KEY的arr值，有函数吗？
2.数组代码：

<code> stdClass Object
(
    [arr] => stdClass Object
        (
            [0] => stdClass Object
                (
                    [id] => 14
                    [cid] => 221
                    [title] => 深圳市轨道交通网络运营控制中心室内精装、玻璃幕墙工程
                    [source] => 
                    [count] => 0
                    [img] => http://upload.55.cn/source/44/201606/50457731d4be5e5c1.jpg
                    [info] => 
                    [fee] => 0
                    [url] => /product/detail/14.html
                    [cate_name] => 装修工程
                )

            [1] => stdClass Object
                (
                    [id] => 12
                    [cid] => 220
                    [title] => 南充嘉陵江1000T级泊位都京码头
                    [source] => 
                    [count] => 0

<code class="php">$resultArr = $targetArr['arr'];</code>

是我理解错了？

是对象应该是 $result->arr 的

把对象转换成数组
$a = $result['arr'];
