Complex problem, delimiter array display of for loop nested inside a while loop

This one takes a big mind to wrap their head around. I get head aches when I do stuff this complex. Ok here is what I am trying to do. I have category and subcategory fields in a field in my database called `cats`, for example, an ipod would be 'consumer electronics|portable audio|mp3 and mp4 players|ipod' and I have below a copy of my code, it is to generate an xml output for google. The code works, but not the displaying the product part. The code I use to display the subcategory works on my main pages of my site, but when I try to add it to this I get no result in the $product_type field. Maybe someone on here can figure it out? Also, the code , you see where I have it subtracting 1? $numberz = $size2-1; on that part? I know that is one thing that is wrong. That counts the number of fields, I need the number  for $numberz to display the number of delimiters in the array return, so when I select the depth to go using the $cats[$numberz] it shows the subcategory for that item. I can't just make it a standard number, it has to be dynamic because some things have a category and are 3 subcategories deep, and others are only 1 subcategory deep. I can tell which one by how many '|' delimiters are in the display. So anyone can figure this one out? Must be Albert Einstein if you can. I am going to take some Excedrin right now..lol!!

I think this is too complex. I am going to post a new topic but for a different approach. I can't figure this out and I don't expect anyone on here to go through this kind of a physical pain headache as this takes. I mean for one like this you really have to keep like 8 things in your mind at all times. Too much. Must be a simpler way. Lets see. I am leaving this one because if someone can modify this code that would be great.

you were trying to use mysql_fetch_row, on a query string. not an actual query. I doubt this alone will fix your issue. but good luck.

i don't real understud what you doing

if you just want to extract last part of string try

<?php
$a = 'consumer electronics|portable audio|mp3 and mp4 players|ipod';
$b = explode('|',$a);
echo $numberz = count($b) - 1;
echo ' last element is: ',$b[count($b) - 1];
// or
//echo $numberz = preg_match_all('/\|/',$a,$b);
?>
