Array value store in session as a string.

I have an array and it looks like this. 

[cuisine] => Array
        (
            [0] => 36
            [1] => 12
            [2] => 2
            [3] => 4
            [4] => 41
            [5] => 22
        )

So now I need to store these values in SESSION. Something like this

$_SESSION['cuisine'] = 36, 12, 2, 4, 41, 22

This is how I tried it, But it doesn't work for me. 

if (isset($_POST['cuisine'])) { 
    $cuisine = $_POST['cuisine']; 
    $noCuisine = count($cuisine);

    if($noCuisine >= 1) {

        $cuisines = '';
        for($i=0; $i < $noCuisine; $i++) {
            $cuisines .= $noCuisine[$i] . ", ";

        }
        echo $cuisines;

        $_SESSION['cuisines'] = $cuisines;
    } else {
        $error_alert[] = "Please select at least one Cuisine.";
    }
} else {
    $error_alert[] = "Cuisine field can NOT be empty";
}

Can anybody tell me whats the wrong with this? Thank you

Make sure you call session_start()

Use $_SESSION['cuisine'] = implode(',', $cuisine) instead of these statements:

$cuisines = '';
for($i=0; $i < $noCuisine; $i++) {
      $cuisines .= $noCuisine[$i] . ", ";

}
echo $cuisines;
$_SESSION['cuisines'] = $cuisines;

$noCuisines[$i] is wrong. $noCuisines is a number, not an array. It should be $_POST['cuisine'][$i].

But that whole loop is unnecessary, since PHP provides a built-in function implode for doing this.

$cuisines = implode(', ', $_POST['cuisine']);

You could also just store the array in the session variable, rather than converting it to a string:

$_SESSION['cuisines'] = $_POST['cuisine'];
