How to modify the array key name in php? This article mainly introduces the method of modifying the key name of the array in PHP, involving PHP's operation skills for array traversal, interception, conversion and other related operations. Friends in need can refer to it. I hope to be helpful.

The example in this article describes how to modify the array key name in PHP. Share it with everyone for your reference, the details are as follows:

$ar = array(
 array(1 => 'a', 2 => 50, 3 => 60, 4 => 'long', 5 => 'zzz', 6 => 'kkk', 7 => 'ooo'),
 array(1 => 'b', 2 => 60, 3 => 70, 4 => 'king', 5 => 'lll', 6 => 'ttt', 7 => 'ppp'),
 array(1 => 'c', 2 => 70, 3 => 80, 4 => 'quit', 5 => 'qqq', 6 => 'xxx', 7 => 'ccc'),
);
$kname = array('StaffId', 'Wage', 'Name', 'Work', 'Type');
function foo(&$v, $k, $kname) {
 $v = array_combine($kname, array_slice($v, 1, -1));
}
array_walk($ar, 'foo', $kname);
print_r($ar);

The running result is:

Array
(
  [0] => Array
    (
      [StaffId] => 50
      [Wage] => 60
      [Name] => long
      [Work] => zzz
      [Type] => kkk
    )
  [1] => Array
    (
      [StaffId] => 60
      [Wage] => 70
      [Name] => king
      [Work] => lll
      [Type] => ttt
    )

    (
      [StaffId] => 70
      [Wage] => 80
      [Name] => quit
