How to remove all 0's (zeros) from an PHP array

If I have the following PHP array

$array = array(9,0,6,4,5,0,9,0,0,0);

and I need to have all 0’s removed from it.

Use the PHP array_filter function. If you don’t supply a callback function it will filter out all values that are equal to false

$new_array = array_filter($array);
