0

I have an array that looks like this:

$array = array("a", "b", 0, "c", 0);

How can I remove all elements with 0 and shift the index of the remaining elements?

I want the result to be like this:

Array ( [0] => a [1] => b [2] => c )

I tried this but it didn't work:

array_diff($bal_units, array(0));

  • call ``array_values`` on the result to reset the index. as: ``array_values(array_diff($bal_units, array(0)))`` https://3v4l.org/f75rN – OMi Shah Jan 03 '23 at 12:11

    `$array = array_filter($array)` – shingo Jan 03 '23 at 12:14

//input

$array = array("a", "b", 0, "c", 0);

$array = array_diff($array, array(0));

if (($key = array_search(0, $array)) !== false) {

    array_splice($array, $key, 0);
}

print_r($array);

RESULT

Array ( [0] => a [1] => b [2] => c )

    But that is an exact copy of what the OP have already tried. And, as the OP said, it indeed doesn't work (index 2 is not element "c"). – chrslg Jan 04 '23 at 00:33
  • I made some code updates. It is currently working in accordance with the specifications. – Noruzzaman Jan 04 '23 at 05:27
