Hello everyone,

I would like to know why you put this character (!) in front of this:
$var1 = "Hello";
$var2 = "hello";
if (!strcasecmp($var1, $var2)) {
    echo '$var1 is equal to $var2 in a case-insensitive string comparison';
Do you see the (!) in front of the strcasecmp() function? That! Why do you put 
that there? 

I'm trying to learn PHP, but it's been kinda hard. THANKS A LOT GUYS!
