Can PHP Be Executed Within a CSS File?

Integrating PHP into CSS

Question: How can you execute PHP scripts within a CSS document?

Answer:

To run PHP code within a CSS file, you need to change the file extension to .php to enable the server to recognize it as a PHP file. Once you make this change, you can link to the file as a regular CSS file. Additionally, ensure that the following header is set at the beginning of the file:

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

Example:

Consider the following code:

/* CSS file: styles.css */
body { background-image:url(../../images/<?php echo $theme.'/'.$background; ?>);}
<code class="html"><!-- HTML file: index.html -->
<link href="css/<?php%20echo%20%24theme;%20?>/styles.php" rel="stylesheet" type="text/css"></code>

By modifying the CSS file extension to .php and including the proper header, the PHP code within the CSS can be executed and the background image can be dynamically set.

Note: It is recommended to use shorttags for efficiency and readability:

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