Lets say, you let each user choose a theme, and the url of the css for that theme was stored in a database. If you are using dreamweaver and want your pages to look nice (ie: WITH a style sheet) while you edit them, use this code.
PHP Code:
<?php
if(1 == 2){
?>
<head>
<link rel="stylesheet" href="default.css" type="text/css" />
</head>
<?php
}else{
echo '<head>
<link rel="stylesheet" href="' . $url_to_stylesheet . '" type="text/css" />
</head>';
}
?>
How this works is:
1) Dreamweaver sees the HTML and renders it.
2) The PHP parser sees the if statement if(1 == 2), 1 does not equal 2, so the html is not rendered.
3) Because 1 does not equal 2, the alternate style sheet is used instead.
Basicly, it uses your stylesheet when your editing it in dreamweaver, but another stylesheet when online.
usefull if you are using dreamweaver...
