Two-dimensional arrays select only target fields

I now have more than 1000 data in the two-dimensional array, the fields in each data are redundant, I now only need my red box in each of the 3 target fields will be OK, the others do not,
I now know to use a double foreach loop to do, but always do not come out, but also ask you to help answer, thank you
The figure is as follows:

Do you want to take out the field you want in the two-bit array, not two times? foreach

  
    mt_rand(1, 2000),        'good_name' => 'goodname' . $i,        'xxxxxxx' => 'xxxxx',        'wadadad' => 'adwawdadwad',        'remake' => ''    ];}//---构造测试数据 ---$data = [];foreach ($arry as $key => $value) {    $data[] = [        'platform_good_id' => $value['platform_good_id'],        'good_name'        => $value['good_name'],        'remake'           => $value['remake'],    ];}var_dump($data);

As follows:

  
   array("a"=>"a","b"=>"b","c"=>"c","d"=>"d","e"=>"e"),    "b"=>array("a"=>"a","b"=>"b","c"=>"c","d"=>"d","e"=>"e"),    "c"=>array("a"=>"a","b"=>"b","c"=>"c","d"=>"d","e"=>"e"),    "d"=>array("a"=>"a","b"=>"b","c"=>"c","d"=>"d","e"=>"e"),    "e"=>array("a"=>"a","b"=>"b","c"=>"c","d"=>"d","e"=>"e"));$result = array();foreach ($arr as $k => $v){    $result[$k] = array();    foreach($v as $key => $value){        if($key === "b" || $key === "d" || $key === "e"){            $result[$k][$key] = $value;        }    }}print_r($arr);print("
");print_r($result);?>

The code above is to extract the element where the key value is b d e and then compose a new array.
