Stripping an array of empty values?

[ppg3412]

This can just as easily be accoplished with loops of some kind, but is there an easier, preferably built-in function of PHP that will strip out 'blank' values from an array?

i.e.:

[0] => Red
[1] => Blue
[2] =>
[3] => Yellow
[4] =>
[5] => Green

into:

[0] => Red
[1] => Blue
[2] => Yellow
[3] => Green

Hmm, not that I know of. And perhaps there should be one ...

I've encountered this issue more than once... 🙁

Also waiting for enlightment,

The closest is array_unique.

Anyway, it's not hard to write a function.

function array_trim($array) {
  $newarray = array();
  foreach ($array as $key => $value) {
    if (isset($value)) {
      $newarray[$key] = $value;
    }
  }
  return $newarray;
}

Pretty nice! The last time I had this issue, I did this, some shopping cart, apparently...

function compact_array($array) {

    for ($y=count($array); $y>0; $y--) {
            $x=($y-1);
            if (((empty($array[$x]) || (!($array[$x])))) && ($array[$y])){
                    $array[$x]=$array['cart'][$y];
                    unset($array[$y]);
                    }
            }
    return $array;
}

Pretty Bass-ackwards, I guess ...
