How to do it get the last non zero value of an array?

[akhileshbc]

<?php

$myarr = array(1,0,22,3,85,69,0,11,2,0,0);    //sample array
$t = array_reverse($myarr); //reverses the array
foreach($t as $ele)    //loop through the elements in array
{
    if($ele > 0)    //if the element is greater than 0...
    {
        echo 'Last non-zero number = ' . $ele; //gives 2 as answer
        break;    // no need to continue the loop since we found an item!
    }
}

?>

No need to reverse the array...

function lastNonZero($list)
{
  for ($i = count($list) - 1; i >= 0; --i)
    if ($list[$i] !== 0)
      return $list[$i];
  return null;
}

Why not just use built in functions?

$array = array(0, 2, 5, 7, 3, 0, 4, 6, 1, 0, 0, 9, 0, 0, 0);

echo end(array_filter($array));
// Returns 9
