I have been looking through this script and came across something that I
dont quite understand how it functions or is used. Basically its brackets
that are added on at the end of a form field value.

EXAMPLE:
<input name="eid[]" type="hidden" id="eid[]" value="<? echo $ses_id; ?>">

in other words what does the [] brackets pass to the function thats
processing the form, basically how is the [] used.

Also here is the part of the script that is processing it., as well as the
more coding of the originating form code
===================
// UPDATE BASKET QUANTITY
if (isset($_POST["UpdateChg"])) {

session_start();
include "functions_cart.php";

$i = 0;
$size = count($_POST["eid"]);

for ($i = 0; $i <= $size-1; $i++) {

// call remove bad characters function
$badsymbols = array(" ","-","+","*","/",".");
$_POST["newquan"][$i] = str_replace($badsymbols,"",
$_POST["newquan"][$i]);

if (is_numeric($_POST["newquan"][$i])) {

// if any quantity's equal 0 then remove from cart
if ($_POST["newquan"][$i] == 0) {
unset($_SESSION["cart"][$_POST["eid"][$i]]);
}

// update quantity in cart.
if (array_key_exists($_POST["eid"][$i], $_SESSION["cart"])) {

add_item_to_cart($_POST["eid"][$i], $_POST["newquan"][$i]);

}

} // END IF NUMERIC

}

header ("location:".$_SERVER['HTTP_REFERER']);

} // END BASKET QUANTITY
==============================
===========================
MORE OF THE FORM CODE

<td class="dividingborder"><input name="newquan[]" type="text"
id="newquan[]3" value="<? echo $ses_quan; ?>" size="5" maxlength="4">
<input name="eid[]" type="hidden" id="eid[]" value="<? echo $ses_id;
?>"></td>
