Wow! u've almost done all the things, thx!! BTW, how to tell PHP which key
is to be used in the 'compare' function? and to facilitate automation, can
PHP interpret the following instead (add something like '\' to let it know
it's unfinished yet?) ?
$table_data= array(
(array ( 'a', 3, 5, 1, 10, 3, 'figA.gif' ))
,
(array ( 'b', 5, 2, 2, 4, 3, 'figB.gif' ))
,
(array ( 'c', 4, 3, 3, 9, 6, 'figC.gif'))
);
