PHP - remove element in multidimensional array

Question

I have this array:

Array ( 
[0] => Array ( [0] => b [1] => d [2] => **c** [3] =>a [4] => ) 

[1] => Array ( [0] => **c** [1] => a          


        

Answer 1

Search the value in the sub array then unset it.

$search = 'c';
$result = array_map(function ($value) use ($search) {
   if(($key = array_search($search, $value)) !== false) {
      unset($value[$key]);
   }
   return $value;
}, $your_array);

Or you could use a loop too:

// this way change your original array
foreach ($your_array as &$sub_array) {
    if(($key = array_search($search, $sub_array)) !== false) {
        unset($sub_array[$key]);
    }
}
var_dump($your_array);
