Based on how you're building your string, you'll want to remove the last
25 characters from it to get rid of the last | and all of the
characters. So, this should work:
$fixed_str = substr($old_str,0,-25);
Or, you could use a regular expression to match the last | and whatever
follows it up to the end of the string.
$fixed_str = preg_replace("/|[^|]*$/","",$old_str);
