SESSION variable size ...

[eluser]sikko[/eluser]
Hi there,

I've got some trouble with session->user data.
I want to save an array in session. And I want this array to be quiet big (50-100 lines).

The array is composed of String variables. Here is a test to show you the problem:

Code:

function add(){

        $playListElement = '0UjsXo9l6I8:"Empire State of Mind" Jay-Z | Alicia Keys [OFFICIAL VIDEO]';
        
        for ($i=0; $i<50; $i++)
        {
            // initialise la playliste
            $playlist = $this->session->userdata('playlist');
            
            // si la playlist n'existe pas
            if(!$playlist)
                $playlist = array();

            $playlist[] = $playListElement;

            $this->session->set_userdata('playlist', $playlist);
        }
    }

The problem is that when I use $this->session->set_userdata, the size of the array is "limited".
And I will be able to save only 33 "$playListElement" in my array. The bigger are the saved Strings, the less I can save (for a bigger string, I can only have 19 elements. etc.)

But when I run this code in pure PHP:

Code:

session_start();
$playListElement = '0UjsXo9l6I8:"Empire State of Mind" Jay-Z | Alicia Keys [OFFICIAL VIDEO]';

for ($i=0; $i<20; $i++)
{
    // initialise la playliste
    $playlist = $_SESSION["playlist"];

    // si la playlist n'existe pas
    if(!$playlist)
        $playlist = array();

    $playlist[] = $playListElement;

    $_SESSION["playlist"] = $playlist;
}
echo "<pre>";
print_r($_SESSION["playlist"]);
echo "</pre>";

There is absolutely no problem: I can save a lot of String, with quasi no limitation (I've saved over 700 elements and I could do more...)

So now, I know the problem is not from PHP session variable size, but from CodeIgniter session variable size...

Do you know how can I bypass this problem ? Or should I just use the $_SESSION variables ?
