i am creating a multiuser game platform using php and i would need to use exec() function and be able to open a socket at port 9999. can i know if this is possible, how much do i need to pay, or if i should switch hosting provider. thanks.
For the user to do what it sounds like he wants to (a game server) he'd need a VPS. Paid hosting forbids constantly-running scripts like game servers and a "multiuser game platform in php" with a socket opened on 9999 sure sounds like a server to me...
