[RESOLVED] Basic Session Question

[harvillo]

Okay...this is very very basic but I have not used sessions that often and have been through a few books with limited results.

Let's say I set pass a var to a session and set if submitted

if($submitrfq) {
$_SESSION['items'][]="$passed_variable";
}

Let's say the set session array is
apple[0]
orange[1]

I'll check for a set session set and loop.

if(isset($_SESSION['items'])) {

foreach($_SESSION['items'] as $key => $value) {

print("$value");

}
}

Great...everything printed

My problem is I'm not sure how to compare the session variable to check if a duplicate exists (say from a refresh).

I've checked all over to no avail...I've seen some close examples but not that involved arrays.

You can always name the session..

<?php

session_start();
$_SESSION['fruit'] = "apple";
$_SESSION['juice'] = "orange";

?>

This way you won't have to check if they are duplicates, you would only pull the information you require.
