Finding the next array row with PHP

Question

I'm working in a code that find the next array value based on the current value but still always returning 1 as result.

$users_emails = array('Spence', 'Matt', 'Marc', 'Adam', 'Paul');

$current = 'Spence';
$keys = array_keys($users_emails);
$ordinal = (array_search($current,$keys)+1);
$next = $keys[$ordinal];
echo $next;

What's wrong?

Answer 1

$keys are the keys, not the value. Use the array with the $ordinal.

$next = $users_emails[$ordinal];

The array_keys gives you an array of the keys. Use your normal array for the array_search as well. Here's a visual of what you currently are building for $keys.

Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 4
)

$users_emails = array('Spence', 'Matt', 'Marc', 'Adam', 'Paul');
$current = 'Marc';
$ordinal = (array_search($current, $users_emails)+1);
$next = !empty($users_emails[$ordinal]) ? $users_emails[$ordinal] : FALSE;
echo $next;
