You can access data from a form in the $HTTP_POST_VARS or $HTTP_GET_VARS
(or $_POST and $_GET in php 4.1) variables.

You can also name all your form elements with a [] on the end, and then
php will construct an array on the fly when the form is submitted. ie:

<input type="text" name="form[]" />
<input type="text" name="form[]" />

and then in your php code, something like

$num = count($form);
for ($i = 0 ; $i < $num ; $i++) {
	//do something with each element
}

(although there's something to be said for not putting []'s in the name
attribute, as they're not allowed according to the HTML spec)

Lots more info on this in the annotated php manual:
