let me give you more details to understand problem with the said code.

go to this link, please.

http://www.abcdefg.us/search/search.php

in search enter, 
Justice, you get response without an error.

Now enter law,

you get error, pasted below,

Warning: usort(): The argument should be an array in /home2/wwwabcde/public_html/search/searchfuncs.php on line 300
------------------------------------------------------------------

below is part of the code and few lines of code above and below the error point, as the code is more tha 300 lies I had to paste tail  end of code at the point of error.
  ----------------------------------------------------------------------

$row[4];

   $res[$i]['size'] = $row[5];

   $res[$i]['weight'] = $result_array[$row[0]];

   $i++;

  }
  usort($res, "cmp"); 

  echo mysql_error();

  $res['maxweight'] = $maxweight;

  $res['results'] = $results;

  return $res;

 /**/

 }

You have written,
Now do a var_dump($res) and see what *is* in $res
or do  print_r().

Can you precisely mention where you want me to put this piece of code.

Please include your original post so we can all see it so we don't have 
to search to find what you're talking about - and highlighting doesn't 
work because most people will get text-only emails.

...........
   $row[4];

   $res[$i]['size'] = $row[5];

   $res[$i]['weight'] = $result_array[$row[0]];

   $i++;

  }

var_dump($res); <---------

  usort($res, "cmp");

Then send us the output.
