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

Example:

If I have the following PHP array

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

Answer:

• 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);
