PHP NOT EQUAL

Jim,
I’m working on some PHP code to try to do what I was saying, but I really don’t know much PHP.

If this PHP code

if ($answer == "water")

means: if $answer = water, then how do you write if $answer doesn’t = water?

Thanks Jim,

Roger

Hi Roger,

In PHP a single equal sign is an assignment operator and used to assign a value to a variable. Two equal signs are a comparison operator, that is, it’s used to compare two values. So, in this case, we use two equal signs to compare the two items: $answer and ‘water’

<?
$answer = "water";
if($answer == "water")
echo "Water!";
else
echo "You need water!"
?>

or

<?
if($answer != "water")
echo "You need water!";
?>

Hope that helps
