# Where to insert mobile redirect code?

 * I have this simple PHP code:
 *     ```
       <?php
       require_once "/_PATH_/_DOMAIN_/class.mobile.php";
       $mobile = new MobileWebarto("http://m._DOMAIN_");
       ?>
       ```
   
 * Obviously, _PATH_ and _DOMAIN_ are placeholders.
 * class.mobile.php identifies whether or not the visitor is a mobile device.
 * On most sites, inserting this code at line #1 of header.php behaves exactly as
   I want and expect.
 * However, some sites do NOT behave as desired.
 * In reality, I want this code to execute PRIOR to any theme code.
 * Furthermore, I don’t want WordPress updates to remove the call to this code.
 * It seems that this code could be inserted into index.php – BUT, where?
 * HOW can this be done WITHOUT future WP updates removing my code?
 * Please, advise. Thank you.
