Title: PHP 5.5 compatibility issue (deprecated notice)

in Product Factory Class, for PHP 5.3+ (core constant PHP_VERSION_ID
available form PHP 5.2.7 is used to check), when closures were available, use
preg_replace_callback instead of preg_replace with /e modifier because
it is deprecated in PHP 5.5.
