You will need
Sockets 3.0.0 Alpha
base64.inc
I use base64 to easily encode the data which can the easily decoded by PHP
I stripped out everything bare minimum that is needed. In this case you would simply call Command_PostExample to execute the connection.
And you can setup your PHP script to save some data to a file to see what all happens and what not.
