array_ filter is pretty much what I need... but it retains the key values. so you may end up with a key set like 0, 3, 5, 6.

How do i reset this? so it doesn't retain the keys...

I swear there is an easy way to do this i can't for the life of me find...

    This should do the trick:

    $newArray = array_values(array_filter($array, 'callback_function'));

      I don't get how that would work... (following example taken from PHP docs)

      $entry = array(
             0 => 'foo',
             1 => false,
             2 => -1,
             3 => null,
             4 => ''
          );

print_r(array_filter($entry));

      outputs;

      Array
(
    [0] => foo
    [2] => -1
)

      and I'm trying to achieve...

      Array
(
    [0] => foo
    [1] => -1
)

      I thought there was a function to reset the array keys or something? I can't find it.

      I'm close to just looping through and doing it manually...

        I thought there was a function to reset the array keys or something? I can't find it.
