The browser is ignoring the file referred on the code below

<link src=”http://siteurl.com/theme/skin/frontend/default/mytheme/css/colors.css.php” rel=”stylesheet” type=”text/css”>
Assume that this is a PHP file that is used as a stylesheet in a Magento extension.
Which of the following choices will make the browser apply the stylesheet?

  • There is no solution; a PHP file cannot be used as a stylesheet.
  • Use the “href” attribute instead of “src” to specify the file’s location, as in:
  • Call a static CSS file instead of using a PHP file as a stylesheet.
  • Send a valid Content-Type HTTP header, as in: header(“content-type: text/css”);
