In one of my php files i am trying to synchronise some stats with another site but it’s having some difficulties with socket_create()

Here’s the message:

Fatal error: Call to undefined function: socket_create() in /home/.hailey/ryanpwest/hlstatsx/hlstatsinc/admintasks/ on line 63

Somewhere I saw a page where you can ask a dreamhost admin to add support for things like this but I cannot find it.
Does anyone know what to do?
