I'm fairly new to PHP. I've used it for basic includes and that's about the extent of my experience, so please excuse me if this is a pretty obvious answer. I'm building a site now where I define certain variables in the top of the page (title, pageID, pageClass... things of that nature). Something like this: [code] <?php $pageTitle = "Welcome!"; //set page title $pageID = "home"; //top level category of page $pageClass = "threecolumncenter"; //layout of page ?> ... <body id="<? echo $pageID; ?>" class="<? echo $pageClass; ?>">[/code] I'm also using the class in the body tag as a way to define the layout of the page (2 columns, 3 columns, 4 columns, etc) using CSS. It's working great. But now, there will be more than just me editing this site so I'd like a way to uncomplicate the CSS class names since they are long and could easily cause typos. To do this, ideally I'd like to use a PHP script that could read something like: <? if ($layout == "3center") set $pageClass == "threecolumncenter"; ?> This way, $layout would be defined at the top of the page like the other variables. I know there's no "set" function, but how could I go about doing this? I've tried everything I could think of, and Googleing but I'm afraid my naivety in how to define this is stopping me from finding an answer. Is this making sense? Thanks... Addam
