Even if an array seems empty like this
if($thisisarray['something'] == '') {}
it might not seems empty enough! as there might be 0's
to do a check do it like this:
remove all 0's and '' then check for empty
$errors = array_filter($thisisarray); if (!empty($thisisarray)) { echo 'do something'; }
array_filter() function's default behavior will remove all values from array which are equal to null, 0, '' or false.
