Although this may or may not help depending on your code (please post it if
you still haven't found a solution...it's the best way for us to help.
Try
SELECT * FROM sessions WHERE sessionID = '$sessionID'
Although if $sessionID contains an integer (which I assume is would) the
quotes aren't needed, you never know. Some OSes are quirky.
Also you may want to add an
echo mysql_error();
line after your initial mysql_query to see if perhaps there's a problem with
PHP communicating with MySQL.
