How to control / monitor bandwidth in PHP ?

[ankurtheking]

Hello,
I am planning to make a paid proxy website where users will have to pay for surfing.
It will cover following aspects..........

When user will create account, he will have to pay by PAYPAL only.
I want to provide instant activation i.e. when payment is made, it will instantly activate his account.

Every user will get specific amount of MB for surfing. Suppose Mr.X is having his limit of 500MB, then he should be able to check how much MB he is used, how much is remaining. When quota is over, his account will be deactivated.

So question is, I can manage user management, but how to make a/c activation after making payment ?

How can I manage Bandwidth quota for each user ?

Off course I am going to purchase VPS for this purpose.

Can anybody help me ?😕😕

Assuming that you're doing this through fopen or curl, you could easily just read the header for the content length and subtract (or add) to their remaining amount (or current use).

If the header doesn't have a content-length header, then you can use [man]strlen[/man] to get the size of the item and convert that around to Megs or Kilobytes as needed.
