[gongpex]

Hello everyone,

It safe or not put php code on css file like this :

<?php
   header("Content-type: text/css; charset: UTF-8");
  
   $db = new mysqli("host", "username", "password", "database");
   if ($db->connect_error) {
		die("Connection failed: " . $db->connect_error);
   }
?>

/* css code */

Q : if not safe please tell me how to use php inside css.

As long as that file is executed by PHP then it's as "safe" as any other PHP file.
