Using PHP and QM to send text to server?

[remotehorsd]

As i found out, i can execute PHP code in QM with this extension:
Executing PHP code in QM
Are there any limitations?

Im not so good in programming, but i need to know the following:

• is it possible to send text via PHP (in QM) from my local computer to a server?
  
• Is that complex to set up?
  
• Can i use my planned macro (if it works) as .exe too?
  
• Is there any other (hopefully a easy) way to send text to a server that a PHP script on the server can handle?
  
• Net doesnt seem to work in exe files, but i need it as exe because i cant buy 10 or more licenses for my friends.

Thanks for any advice!
