Illegal string offset Warning PHP

I get a strange PHP error after updating my php version to 5.4.0-3. I have this array: Array ( [host] => 127.0.0.1 [port] => 11211 ) When I try to access it like this I get strange warnings print $memcachedConfig['host']; print $memcachedConfig['port']; Warning: Illegal string offset 'host' in .... Warning: Illegal string offset 'port' in ... I really don't want to just edit my php.ini and re-set the error level.
