Question

I have an array of elements in PHP called…

$completeArray

…and I’m trying to store a randomized version of this array in my session called…

$_SESSION['videoArray']

…so I’m trying something like this…

$_SESSION['videoArray'] = shuffle($completeArray);

…but when I try to echo the first element of this randomized array like this…

$videoid = $_SESSION['videoArray'];
echo $videoid[0];

…all it’s returning is the ‘key’ of the element. How do I randomize the array and be able to echo the actual elements of the new array?

Answer 1

shuffle take a reference of an array and Returns TRUE on success or FALSE on failure.

You should do:

shuffle($completeArray);
$_SESSION['videoArray'] = $completeArray;
