This is what i mean: $var=''; if(empty($var)) { echo "perfect and desired"; } whereas .. $var=0; or $var='0'; if(empty($var)) { echo "undesired but still true"; } so for such cases i advise you, to use this: if(empty($var) && $var!=0) { echo "will not be printed if var is zero"; } http://php.net/manual/en/function.empty.php
