I need to post some data from one server to another just like what a form does client side. Data (a few strings totalling ~500 charactors) is received on one server (and can only be received on this server) and has to be sent to another server so that it can be added to a database. However...

On the server which adds the info to the database:
allow_url_fopen = off (and can't be turned on!!)
which means fsock isn't an option

I thought this would be a really simple thing to do (because it is client side!) but I have no idea how I can solve this so many thanks for any help!
