二维数组追加键值对

 1 $wid=$this->_post(‘order_id‘);
 2 if(!$wid){
 3     echo(‘工单信息获取失败!‘);
 4     exit;
 5 }
 6 $where=null;
 7 $where[‘A.wid‘]=$wid;
 8 $list=M(‘kefu_reply‘)->alias("A")->join(‘z_user_common as  B on  A.uid=B.id‘)->
 9 where($where)->field(‘A.*,B.realname,B.account‘)->order(‘A.do_time desc‘)->select();
10 foreach ($list as $key => $value) {
11     if(mb_strlen($value[‘content‘])>15){
12         $list[$key][‘content_new‘]=mb_substr($value[‘content‘],0,6,‘utf-8‘); 
13     }else{
14          $list[$key][‘content_new‘]=$value[‘content‘];
15     }
16     $list[$key][‘dotime‘]=date("Y-m-d H:i:s", $value[‘do_time‘]);
17 }
18 //dotime是追加的键值
