please explain this line of code to me

[sean_paul]

$url = "show_cat.php?catid=".($row["catid"]);

what is "php?" doing in the center of this code?

[getDizzle]

That's just a url "show_cat.php" and ?catid=".($row["catid"]) is just passing the sql table result as a variable to show_cat.php. So the $url will probably be in the script as:

<a href="http://www.whatever.com/$url">LINK TEXT</a> and the link in a browser would be:

http://www.whatever.com/show_cat.php?catid=999
