How to Execute PHP Code Within a CSS File?

Executing PHP Within CSS

Executing PHP code within a CSS file requires a unique approach. By default, CSS files do not support PHP execution.

To achieve this, you can modify your CSS file's extension to .php so that the server recognizes it as a PHP file. Link to the modified CSS file using the following syntax:

<code class="html"><link href="css/<?php echo $theme; ?>/styles.php" rel="stylesheet" type="text/css" /></code>

Remember to place the following header at the beginning of the CSS file:

<code class="php"><?php header("Content-type: text/css"); ?></code>

Furthermore, since PHP shorttags are enabled, you can simplify the PHP echo statements within your CSS code:

<code class="css">body { background-image: url(../../images/<?php echo $theme.'/'.$background; ?>); }</code>

This approach allows you to dynamically generate background images and other CSS properties based on PHP variables, providing greater flexibility in customizing your website's presentation.
