Variable help (very quick)!

Hey php'ers.

I'm struggling on a variable thing.

Code is.

<?php 
//determines which board to post chat to...
if ($_GET['board'] == "chat") {
$board_cat == "chat" ;
} elseif ($_GET['board'] == "request") {
$board_cat == "request" ;
} else { $board_cat  == "null" ; }
?>
<head>
<title>PHP</title>
</head>
<body>
<? echo "$board_cat" ?>
</body>

Does anybody have any idea why $board_cat isn't displaying echoing onto the screen?

(I want $board_cat to echo chat when ?board=chat, I want $board_cat to echo request when ?board=request and if ?board is something other than chat or request, i want $board_cat to echo null!

Can anyone plz help.

Cheers,

nicknax

When you set a variable, use =

= is for setting variables.
== is for comparison.

Like intenz said if you're setting a variable as something use the = operand. Using == is saying "equal to" and seeing if it's equal to that. It's not setting it to that text.

Checkout Larry Ullman's PHP Visual Quickstart Guide. It's a great introduction book for PHP newbies. I read it and love it. He has an advanced one as well as a PHP & MySQL (which I am currently working through).

Also I think you need a semicolon after
your closing quote in the echo statement.

True, but if it's the last line in the script the ?> terminates the script and there is no need for the ; but it is better habit to add it in there.
