I plan to design the web page with the member ship. Only member make the PAYMENT have the function. Non-membership would be only LIMIT access and function .   Whether membership or non-membership can create the personal profile and adjust the profile as well.  It contains the personal profile with security permission, it saves to the DB.

May I know what is the language can fulfilled the requirements.
 Many languages can, my favorite is Perl through an Apache server. But if you have monetary transactions with credit card numbers etc, I'd use an alternate source for electronic commerce processing such as paypal or another CLEARING house as for processing at your end opens up liabilities. The last place I worked at we had to harden our network and Point of Sale system with PCI COMPLIANCE and we went with an outside source for eCommerce to isolate ourselves from potential liabilities.What KIND of a "web page"?  You could use something like Simple Machines Forum, which has all sorts of modules for subscription-based access using PayPal or whatever.
