17 CHH512.001
18 CHH620N. 001
19 CHH620N. 002

How does one implement detailed grouping using php ??? Thank you very much.

------ Solution --------------------
$ Id = array (1, 2, 3, 4, 5 );
$ Pac = array ("ABC001", "ABC002", "ABC003", "ABC004", "ABC005 ");
$ Num = array (". 001", ". 002", ". 003", ". 004", ". 005 ");
$ D = array_map (null, $ id, $ pac, $ num );
Print_r ($ d );
?>
So?
