socket_create() is undefined -- why?

[watermelon14]

I am using PHPTriad in Windows98. I am developing a client socket with PHP and server socket with java

When i try to create client socket with function --socket_create (AF_INET, SOCK_STREAM, 0), it said it is undefined function.

1. Why does this happen? any special libraries is needed for socket programming in PHP?

2. Some people said that I need to compile PHP with the --enable-sockets option? Is it a Unix or linux command? Where should i compile with this option in Windows platform?


thank a lot
