Solution 1

What is the source of $row ? That would be ever so helpful in diagnosing your error.

mysql_fetch_assoc is expecting a rowset, which is the return value from a successful (SELECT) via mysql_query().

Try this :

PHP

<?php

         $current_cat = null;
         $data[]=null;

        while($row = mysql_fetch_assoc($categories))
        {
        $data[] = $row;
        }

        foreach($data as $item)
        {
          if ($item["title"] != $current_cat)
          {
           $current_cat = $item["title"];
           echo $current_cat;
          }
          else
          {
           echo $item["title"];
          }
        
        }

         ?>
