Display Format

Hi, I`m using the following code to display the contents of a file..... <? $filename = "category/category.inc"; $fd = fopen ($filename, "r"); $contents = fread ($fd, filesize ($filename)); fclose ($fd); $content = explode (",", $contents); for ($a=0;$a<count($content);$a++){ printf("<TR><TD><A HREF='showcat.php?Cat=%s'>%s</A></TD></TR>", str_replace(" ","",strtolower($content[$a])), $content[$a]); } ?> It is working fine at the moment but I want to try and be a tad more ambitious, say for example the category.inc contains the following: Paul,Mark,Tom,Ade My code will display the results like so... (Obviously with my HTML in there too) Paul Mark Tom Ade Firstly is there any way I can sort these in alphabetical order?? More importantly is there any way of formatting them so they display Paul Mark Tom Ade So they are in two columns in a table rather than one?? Thanks for any help Ade
