store a php array in session from input form

I am having allot of trouble trying to get an array to work with sessions if anyone can help that would be great I'm not bothered about validation etc if I can just get it working i can then expand upon it.

HTML

<form method="post" action="array2.php">
    Select amount of tickets you require.
    <select name="options[]">
        <option value="1">1</option>
        <option value="2">2</option>
        <option value="3">3</option>
        <option value="4">4</option>
        <option value="5">5</option>
        <option value="6">6</option>
        <option value="7">7</option>
        <option value="8">8</option>
        <option value="9">9</option>
        <option value="10">10</option>
    </select>
    Select the acomidation you require.
    <select name="options2[]">
        <option value="camping">Camping</option>
        <option value="caravan">Caravan</option>
    </select>
    <input type="submit" value="Go!" />
</form>

array2.php

<?php
session_start();
$checked = $_POST['options'];
$checked2 = $_POST['options2'];
$_SESSION['user'] = true;
$_SESSION['checked'] = $checked;
$_SESSION['checked2'] = $checked2;
header('Location: array3.php');
?>

array3.php

<?php
session_start();
if(!isset($_SESSION['user'])){
    die("To access this page, you need to <a href='register.html'>LOGIN</a>");
}
$checked = $_SESSION['checked'];
$checked2 = $_SESSION['checked2'];
?>

<?php
    for($i=0; $i < count($checked && $checked2); $i++){
        echo "You have selected to receive " . $checked[$i] . " tickets<br/>";
        echo "And you have selected to receive " . $checked2[$i] . " for accommodation are you sure? <br/>";
    }
?>

The main problem is that the values are not being passed from array2 into array3, any help is welcomed.

EDIT - this worked fine until I tried to add in the sessions to get it working over multiple pages so I'm sure thats where the problem is

EDIT2 - thanks for all the help guys i got it working when I took out

$checked = $_POST['options'];
$checked2 = $_POST['options2'];

From array 3 it worked :) much appreciated!

Your for loop is written wrong.

for($i=0; $i < count($checked && $checked2); $i++)

That count statement will not work as you think. Break it into 2 for loops or an inner loop.

like this:

for($i=0; $i < count($checked); $i++){
  echo stuff here
}

for($i=0; $i < count($checked2); $i++){
  echo stuff here
}

count($checked && $checked2)

...is your problem.

$checked && $checked2 is a logical expression will either be true or false, which means thats the count() call will always return false, and false will equate to 0 in a numeric comparison (the less than < comparison with $i), so the for loop won't perform any iterations.

However, the use of arrays in this situation is not appropriate anyway, because you have used a <select> element without a multiple property so it will only represent a single value, which means the array would only ever hold a single value. You should simplify this to just scalar values and you will find that a) it works and b) it's much easier in general.
