How to write code like "form.php?id=002"

I found that someone can use PHP like CGI. How could I write code like "form.php?id=0023" or sort of like that?

Thanks

To get the value of id, you just use:

$_GET['id'] or $HTTP_GET_VARS['id'] depending on the version of PHP you use. If it's greater than 4.1.0, use the first one.

And then you use that value whatever way you want - to query a database, or whatever.

When I retrieve my data, generally I used

simplified code:

$row = mysql_fetch_array($result);
$row["id"];

If I used $GET['id'] or $HTTP_GET_VARS['id'], where I should use $GET["ID"]? Do I need to query special table?

Sorry to ask questions like these?

Take a look at:
