Last PHP Question - I promise

Hi.

I have one last final problem with PHP sessions.

Please take a look at the attached small screen shot. Each session is called [game1] all the way down to game20]

If the database is full for all sessions except [game8] users will see a blank line where [game8] should be.

Is there anyway to move [game9] up one line to prevent the blank space?

Also, as a rule of thumb, I would need such a script to ignore any blank sessions and move all the full lines towards the top.

Thanks VERY much for reading. I promise this is my last question

David.

You Should probalbly use this instead:

Code:

$detect = mysql_query("select `field` from `table` LIMIT 0, 20");
while ($row = mysql_fetch_array($detect, MYSQL_BOTH)) {
   printf("%s", $row[0]); 
}

or at least this is what I think you're trying to do.

Im just looking for a simple script that will ignore blank fields and move the next field containing data upwards to prevent users seeing blank lines on pages. Thanks for trying though. __________________ C905 - Sony Ericsson mobile phone with an 8 megapixel camera!
