PHP array_map for multidimensional arrays

Array map is one of the interesting PHP’s array function. But it will not work with multidimensional arrays as expected.So in this post, I would like to share a simple alternative technique for array_map(). Our function will work like array_map but it will support multidimensional arrays.

 function my_array_map($function, $arrary)
{
  $result = array();
  foreach ($arr as $key => $val)
  {
      $result[$key] = (is_array($val) ? my_array_map($function, $val) : $function($val));
  }
  return $result;
}

function my_array_map($function, $arrary)

{

$result = array();

foreach ($arr as $key => $val)

{

$result[$key] = (is_array($val) ? my_array_map($function, $val) : $function($val));

}

return $result;

}

Here we used recursive function methodology and the Ternary Operator syntax.

How to use

you can use my_array_map just like as array_map().

 $array = array('test ',array('website' => 'arjun php '));
  my_array_map('trim',$array);

1 2	$array = array('test ',array('website' => 'arjun php ')); my_array_map('trim',$array);

That’s it.
