php 一维数组拼接到二维数组后面

$list = [
     ['name'=>'thinkphp','email'=>'thinkphp@qq.com','color'=>'thinkphp@qq.com'],
     ['name'=>'onethink','email'=>'onethink@qq.com','color'=>'thinkphp@qq.com']
 ];$new = ['http:www.a.img','http:www.b.img'];
foreach($list  as  $k=>$val){
     $list[$k]['image'] = $new[$k];
     
 }
 print_r($list); 结果如下：
  Array
 (
     [0] => Array
         (
             [name] => thinkphp
             [email] => thinkphp@qq.com
             [color] => thinkphp@qq.com
             [image] => http:www.a.img
         )    [1] => Array
         (
             [name] => onethink
             [email] => onethink@qq.com
             [color] => thinkphp@qq.com
             [image] => http:www.b.img
         ))
