Socket help

Hello list, I need to receive/send sms through an IPSec connection using the socket (pfsocket) function of php. I hope there's someone out there that can help me solving some questions. Here is what I thought to do: REC_SCRIPT that open the socket connection and listen on arriving messages (msg will be stored in mysql) SEND_SCRIPT that is launched from a html form and use that socket to send the message and store it in myslq. Questions 1. Can the REC_SCRIPT stay alive listening on the persistent socket connection ? 2. There's a way to launch it automagically when I start apache ? 3. Can the SEND_SCRIPT use the socket conn. opened by the first script ? 4. In case of receive/send in the same time, will all be ok ? Thank you very much for any help Stefano Baronio sbaronio@sateltrack.com www.sateltrack.com
