How to Execute PHP Commands within CSS Stylesheets

Question:

I need to implement PHP code within my CSS stylesheet to display a DB-generated background image:

<link href="css/<?php echo $theme; ?>/styles.css" rel="stylesheet" type="text/css" />
body{ background-image:url(../../images/<?php echo $theme.'/'.$background; ?>);}

I attempted adding the following header, but it merely outputted the code in HTML format:

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

Answer:

To successfully run PHP code inside CSS, follow these steps:

  1. Change the file extension to .php:
    Switch the extension of the CSS file to .php so the server can execute PHP commands.

    Change:

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

    To:

    <link href="css/<?php echo $theme; ?>/styles.php" rel="stylesheet" type="text/css" />
  2. Include the correct header:
    At the beginning of your .php file, include the following header:

    <?php header ("Content-type: text/css"); ?>
  3. Shorten PHP tags:
    For convenience, use the shortened PHP echo syntax:

    Change:

    <?php echo $var; ?>

    To:

    <?=$var; ?>

By following these steps, you will be able to run PHP code dynamically within your CSS stylesheets.
