[SOLVED] Array in PHP Session

[eutu9]

I am trying to insert an array into a PHP session

 

I tried this way:

$products[0]="product 0";

$products[1]="product 1";

$products[2]="product 2";

 

$_SESSION['products']=$products;

 

 

I tried this way:

$_SESSION['products'][0]="product 0";

so on...

 

When I am trying to acces the products:

 

foreach($_SESSION["products"] as $key=>$value)

{

    echo $key."-".$value;

}

 

all I get is:

0-

1-

2-

...

 

It doesn't writes the values! I tried to do it multiple ways!

What is my mistake?

 

How can I add an array to a session? I googled it and I can't see where is my mistake.

Maybe u can help me!

 

Thanks!

$products[] = "product 0";
$products[] = "product 1";
$products[] = "product 2";

$_SESSION['products'] = $products;

// foreach loop or whatever you want on $products or $_SESSION['products']

I tried that! Still not working

Try

$_SESSION['products'] = serialize($products);

 

Remember to unserialize() it when you need to get it again.

This works... not sure exactly what you want to do, but it displays what it's supposed to..

 

<?php
session_start();
$products[] = "product 0";
$products[] = "product 1";
$products[] = "product 2";

$_SESSION['products'] = $products;

foreach ( $_SESSION['products'] as $key => $value ) {
    echo $key . ' - ' . $value . '<br>';
}
?>

My guess is that your code is clearing the values at some point or that register globals are on and $_SESSION['products'] is getting overwritten.

 

Post your actual code.

 

Note: serialize/unserialize is not needed to store arrays in sessions (in fact the session code serializes and unserializes the data when it stores and retrieves if from the session data file.)

I have found the problem! The values were empty because I forgot to fetch the result mysql row  !

 

Sry for bothering you! Next time I will pay more attention!  ???

 

Any code from above works just fine!  Thank you for your help and sorry again !
