How to re-index all subarray elements of a multidimensional array?
To reset the keys of all arrays in an array:
$arr = array_map('array_values', $arr);In case you just want to reset first-level array keys, use array_values() without array_map.
$array[9] = 'Apple';$array[12] = 'Orange';$array[5] = 'Peach';$array = array_values($array);through this function you can reset your array
$array[0] = 'Apple';$array[1] = 'Orange';$array[2] = 'Peach';
Use array_values to reset keys
foreach($input as &$val) { $val = array_values($val);}
