 * I’m storing a value into a variable I’ve created called $mov_sub. I’m using the
   Exec-PHP plugin to put PHP into posts. This is the PHP I’ve got in my post:
 * `<?php mov_sub = "123"; ?>`
 * Then I’ve got a file included using PHP in my header.php file. The source code
   for the included file is along the lines of:
 *     ```
       <?php
   
       if(is_single( array( 1079, 1088 ) ) )
   
       if(isset($mov_sub)) {
       	$sid = "&sid=$mov_sub";
       }
       else {
       	$sid = "&sid=";
       }
       	echo "$sid";
       }
       ?>
       ```
   
 * It’s only echoing &sid, not &sid=123 like it should be doing. I tested this outside
   of WordPress and it works fine. I thought maybe it wasn’t working because WordPress
   uses a function to create the post content called the_content() and I think functions
   only allow local variables unless you declare a global variable. So I edited 
   the post-template.php file in wp-includes where the_content() function is located
   and added:
 * `global $mov_sub;`
 * but that didn’t work either. I’m really new to PHP and have been struggling with
   this for a few hours now. Does anyone know why it’s not working?
