Description:
------------
The in_array function does not seem to be able to find the word 'array' inside an array.

Test script:
---------------
$arr = array(
    '​array',
);

echo in_array('array', $arr) ? 'it\'s there' : 'it\'s not there';

Expected result:
----------------
it's there

Actual result:
--------------
it's not there
