検索結果をPHPの配列から取得するには？

Question

私は配列を持っています。

Array 
(
    [0] => Array 
     (
      [0] => <img src='http://dev-gym-management.pantheonsite.io/wp-content/uploads/2017/03/images-5 
.jpg' height='50px' width='50px' class='img-circle'/> 
      [1] => Anna Khan 
      [2] => Personal Trainer 
      [3] => anna@gmail.com 
      [4] => 990099000 
      [5] => <a href='?page=gmgt_staff&tab=add_staffmember&action=edit&staff_member_id=5 class 
='btn btn-info'>Edit</a><a href='?page=gmgt_staff&tab=staff_memberlist&action=delete&staff_member_id 
=5' class='btn btn-danger'>Delete</a> 
     ) 

) 

私は、検索配列にしようとしているが、正常に動作していないよ。私は「アンナ・カーン」で検索したい場合は

Array 
(
    [0] => Array 
     (
      [0] => <img src='http://dev-gym-management.pantheonsite.io/wp-content/uploads/2017/03/images-5 
.jpg' height='50px' width='50px' class='img-circle'/> 
      [1] => Anna Khan 
      [2] => Personal Trainer 
      [3] => anna@gmail.com 
      [4] => 990099000 
      [5] => <a href='?page=gmgt_staff&tab=add_staffmember&action=edit&staff_member_id=5 class 
='btn btn-info'>Edit</a><a href='?page=gmgt_staff&tab=staff_memberlist&action=delete&staff_member_id 
=5' class='btn btn-danger'>Delete</a> 
     ) 

    [1] => Array 
     (
      [0] => <img src='http://dev-gym-management.pantheonsite.io/wp-content/uploads/2017/03/images-4 
.jpg' height='50px' width='50px' class='img-circle'/> 
      [1] => Jobaer Rahman 
      [2] => Personal Trainer 
      [3] => jobaer@gmail.com 
      [4] => 55555555 
      [5] => <a href='?page=gmgt_staff&tab=add_staffmember&action=edit&staff_member_id=3 class 
='btn btn-info'>Edit</a><a href='?page=gmgt_staff&tab=staff_memberlist&action=delete&staff_member_id 
=3' class='btn btn-danger'>Delete</a> 
     ) 

    [2] => Array 
     (
      [0] => <img src='http://dev-gym-management.pantheonsite.io/wp-content/uploads/2017/03/images-3 
.jpg' height='50px' width='50px' class='img-circle'/> 
      [1] => Milon Khan 
      [2] => Fitness Instructors 
      [3] => milon@gmail.com 
      [4] => 7777777888 
      [5] => <a href='?page=gmgt_staff&tab=add_staffmember&action=edit&staff_member_id=4 class 
='btn btn-info'>Edit</a><a href='?page=gmgt_staff&tab=staff_memberlist&action=delete&staff_member_id 
=4' class='btn btn-danger'>Delete</a> 
     ) 

) 

は今、私のような結果を必要としています。複雑さを軽減するために、私は生のコードを使用しません。任意の最も簡単な方法やこれを行うPHPの配列関数？

Answer 1

$data = [array here]; 
$search_str = 'Anna Khan'; 

array_walk_recursive($data, function($item, $key) use ($search_str) { 
    if (stripos($item, $search_str) !== false) { 
     echo $key; // or any action you want. 
    } 
});
