   Hi there, i'm having some problems with:

   <?php echo(get_category_parents($cat, TRUE, ' » ')); ?>
   it returns: INTERNET » SOCIAL MEDIA » TWITTER » MARKETING

   I'd like to output this:
   MARKETING » TWITTER » SOCIAL » MEDIA » INTERNET

   is there any way i can do that?

   thx

   This should do the trick:

   $sep = '»';
   $parents = get_category_parents( $cat, TRUE, $sep );
   $parents = explode( $sep, trim( $parents, $sep ) );
   $parents = array_reverse( $parents );
   $parents = implode( " $sep ", $parents );
   print $parents;

   Some categories lost letters in the end of the word when using Michael Fields trick. I changed the code a little bit and now it seems to work. I don't know what this bug came from. It works when I use:
   

   if(is_archive()){
   $sep = " ‹ ";
   $parents = get_category_parents( $cat, FALSE, $sep );
   $parents = trim($parents);
   $parents = explode($sep,$parents);
   $parents = array_reverse($parents);
   $parents = implode(" ",$parents );
   print $parents . " ‹ ";
   }

   The problem seems to occur when I using the explode() and trim() at the same row...

   @smeknamn great catch! Sorry for the oversight. Sometimes I forget what the second parameter passed to trim() actually does. Instead of removing the string trim() removes the individual characters as shown in the Hello World example in the docs: http://php.net/manual/en/function.trim.php
