Can PHP and pureBasic communicate through port 80?

[Alberto]

I explain better my question.

My company wants to make available through internet to his distributors the disponibility, the prices and other few things of our database.

The normal way is to make a web server but I don't like this way because a Windows web server is very dangerous to administrate for security (it needs continuous updates and a really expert for security) and is also expensive.

I ask you if it's possible to do a tunnel through port 80 that pass our LAN firewall. The purpose of this tunnel is to communicate with our website located on a internet server outside from our LAN.
When a distributor wants to know the disponibility or to reserve a product he communicates with our web site located in Internet. Our website contains PHP functions that communicates through port 80 to a purebasic program running on the server of our LAN.

It's like the idea behind the SOAP but made in pureBasic.

I know how to connect to our database using pureBasic.
I know how to scan continuously a computer port for a comunication in PureBasic.

I don't know how to realize a communication from a PHP program and a Purebasic that acts like a server on a machine located in a LAN where there is a firewall and the only way to go in or out is the port 80 (the security is guaranteeed)

Any suggestion?

Thank you in advance.

Alberto,

Have you looked at the Atomic Web server example? You'll find it in the "Sources - Advanced" folder.

You can split the code into two parts: the port listener which listens for requests and the protocol handler.

The protocol handler just converts the request into a path on the web server and then returns the file it refers to.

You will want to replace the protocol part with one that fits your requests. Something that identifies whatever you'll be publishing rather than files on a server.

PHP would then access Purebasic on port 80 the same way it would any other server over the web.

Something like:
$fp = fsockopen("url.or.ip", 80, $errno, $errstr, 30);

Docs are here:

Thank you for your answer GedB.

It's always a beautiful surprise for me to find people like you that help
their pureBasicbrother.

Your solution is very good.

I also think that the fsockopen is the right function to use in PHP but I can't understand what put in the "url.or.ip" parameter.

I'm connected with an ADSL connection that has a static IP that is 63.123.041.111 (for example). The router/firewall is than connected to a hub and a LAN. In the LAN the computer where run my AtomicWebServer (or a modified version of it) is 192.168.11.1 (for example).

What I've to write in the "url.or.ip" parameter of the fsockopen function?

Thank you for your answer.

alberto, do a search on the forum, i've posted a winsock example if you want to do it directly yourself with winapi's
