E_ERROR: Cannot redeclare OpenTok\Util\array_is_list() (previously declared in/opentok/opentok/src/OpenTok/Util/Validators.php:465

[dbrzoska]

When I call generateToken method more than one time in code execution have this error.
I think function_exists does not work property fine. If you use function declaration in other function you need to add namespace.

if i change in src/OpenTok/Util/Validators.php (464 line)
if (!function_exists('array_is_list')) {
to
if (!function_exists('\OpenTok\Util\array_is_list')) {
its works fine.

We are having the same issue with version 4.14, and have had to revert to 4.10 as a workaround at the moment.
