what difference among these paypal payment methods. want integrate oscommerce.

paypal website payments pro (us) direct payments
paypal express checkout
paypal ipn
paypal website payments standard
paypal website payments pro (uk) direct payments
paypal website payments pro (uk) express checkout

paypal website payments pro (us) direct payments paypal api-based solution allows take card payments directly on site. in addition, has $30 monthly fee , account needs checked paypal. lastly, need pci dss compliant.

paypal express checkout api-based solution doesn't require buyer enter details on site, allowing them quick checkout through paypal site. (although it's not required. can still request address on cart if wish). there no monthly fee , free use it.

paypal ipn instant payment notification. in basic terms, paypal notify script on site via post whenever payment has gone through. great sending out customized 'thank you' emails, updating order database / stock levels, etc. believe oscommerce uses updating order status. oh, , it's free well.

paypal website payments standard: forget it. it's same express checkout, worse , more insecure.

paypal website payments pro (uk) direct payments: older version of website payments pro available time in uk. you'll know if have this, otherwise forget it.

paypal website payments pro (uk) express checkout: 100% same paypal express checkout. not sure why have available second time.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
