   I need to feed into my code a list of the categories for a post in separated by ampersands (&) .... this is because I have create a loop on my single php so I can show related posts but only for the categories this single.php-based post is in. So, the loop requires the post id if I am to limit it to just outputing posts from that those categories ... any ideas? I am using the function below to list the categories by name separated by a comma ... all I need is the same thing for post ids but separated by &

   <?php the_category(','); ?>

   Any help would be greatly appreciated.

   Did you try:
   

   <?php the_category('&'); ?>

   Yes, but this function outputs category names and I need it to output their numerical category id

   <?php
   $metas='';
   foreach(get_the_category() as $cat) {
     $metas .= $cat->cat_ID . '& ';
   }
   echo substr($metas,0,-1);
   ?>
