PHP 数组的问题，如何模糊筛选数组并生成新的数组（解决）

Question

假如我要筛选 TRADE_STATUS =>交易失败这四个字，然后关于交易失败的这个组全部提取出来。生成新的组
本人菜鸟，我已经看了几十篇帖子，到目前也没有解决，本人愚钝，还望大哥大姐能给个完整的代码。

 Array ( [0] => Array ( [ORDER_DATE] => 2018-04-16 [ORDER_NUMBER] => 148548269824540472 [SHOP_NAME] => 友诚票务 [COMMODITY_CONTENT] => 友诚票务 高铁G1019 广州南-深圳北 [COMMODITY_PRICE] => 74.50 [COMMODITY_NUMBER] => 1 [COMMODITY_STATUS] => 投诉卖家 [COMMODITY_PAY] => ￥74.50(含运费：￥0.00) [TRADE_STATUS] => 交易关闭,订单详情 [USER_ID] => 6fb8dabada042e58386a21a1516bc50e ) [1] => Array ( [ORDER_DATE] => 2018-04-12 [ORDER_NUMBER] => 147644907367540472 [SHOP_NAME] => 寻梦网络服务 [COMMODITY_CONTENT] => 爬虫代写,信息抓取,正则表达式代写,程序定制,数据采集抓取软件 [交易快照] [COMMODITY_PRICE] => 20.00 [COMMODITY_NUMBER] => 100 [COMMODITY_STATUS] => 查看退款,投诉卖家 [COMMODITY_PAY] => ￥2000.00(虚拟物品) [TRADE_STATUS] => 交易关闭,订单详情 [USER_ID] => 6fb8dabada042e58386a21a1516bc50e ) [2] => Array ( [ORDER_DATE] => 2018-04-05 [ORDER_NUMBER] => 553813995204 [SHOP_NAME] => 飞猪机票自营 [COMMODITY_CONTENT] => 深圳航空 ZH9518 上海-深圳单程起飞时间：2018-04-05 21:00:00 [COMMODITY_PRICE] => 544.00 [COMMODITY_NUMBER] => 1 [COMMODITY_STATUS] => 投诉 [COMMODITY_PAY] => ￥594.00(含运费：0.00) [TRADE_STATUS] => 订票成功,订单详情 [USER_ID] => 6fb8dabada042e58386a21a1516bc50e ) 

自己解决了

 $keywords = '关闭';
$arrays = $this->taobao_yanhao_model_c->listinfo($where,'*',0,0, 1000,'',$this->taobao_yanhao_model->page_size);
$arr = array();
foreach($arrays as $key=>$values ){
    foreach ( $values as $s )
    if (strstr( $s, $keywords ) !== false ){
        array_push($arr, $values);
    }
}

print_r($arr);
