I recommend you to use session variables on guarding shopping values
$_SESSION['name']=value;
when no longer necessary delete it with unset(variable);

You can/should use arrays:
to asing values (it's only an example, $item is the total of items in this sample)
| Code: |
for ($n=0;$n<$item;$n++){
$_SESSION['item'][]="item".$n;
}
|
Note that in PHP not asigned name/value to an array position (like in my example) is valid, PHP auto asigns the next value, so you can get all the content of an array in this way:
| Code: |
for ($n=0;$n<count($_SESSION['item' ]);$n++){
echo $_SESSION['item'][$n]."<br>";
}
|
PHP it's more flexible than COBOL :-P
