persistant cart tut, with no SQL!

Hi all, I am looking for a way to display the contents of my shopping cart without using a database for the time being. I have it down so I need to spit out everything in the $_SESSION array that has a value, but am lost on the way to start. Basically whenever someone clicks "add to cart", I then set the registered variable with a value. Then comes checkout time and everything has to be displayed. I have tried this but won't work...

for($i = 0; $i <= sizeof($_SESSION); $i++) {
if(isset($_SESSION['$i'])){
echo $_SESSION['$i'];
}
}

Any help would be greatly appreciated. I know of all the "free" scripts out there, but haven't found one that I understand completely yet, and I want to learn this for myself

You can try out with a foreach structure :

foreach($_SESSIONS as $key => $value) {
echo $value;
}

But you surely want to add up some validation on what is displayed, so maybe someting like :

foreach($_SESSIONS as $key => $value) {
if ($key == "whatever")
echo $value;
}


hope it will help

ciao!

Thanks for the response. I'll give it a shot

were you able to figure out how to do this? I would be interested in seeing the results if so.
