John Imbong's List: Web Optimization

• PHP is an embedded technology, meaning you can combine the logical/programming code with normal HTML or XHTML markup. In a more general sense, the output can be any text you like—in this case, it’s CSS.
• Normally, PHP and the Web server it’s running under will automatically tell the browser that a PHP script is HTML. In the case of a static CSS file, the server knows it’s CSS by the file extension. But this is a special case, so our first job is to send the correct media, or MIME type to the browser using the PHP header() function:
• header('Content-type: text/css');
• The next step is to define the color scheme sets using associative arrays.
