I would like to know why you put this character (!) in front of this:

Nearly unanimously to all programming languages, the bang (!) symbol indicates "not" or "negative" or "inverse" or "not true". So you use it when you want to indicate that something is "not the case" or if you are performing a test for the lack of a condition rather than the condition itself. Like this: if ($var) { echo "Yes, var exists"; } elseif (!$var) { echo "No, there is no variable called var"; } else { echo "You cannot reach this part of the if statement.

        Either var exists or it doesn't";
