php and sms headaches!

[obyno]

For a zillion days now I have been struggling with what I thought should have been a simple code.It is meant to accept a keyword from a mobile phone sent by sms to a page theoretically called smstry.php; and this page should if the keyword is correct send off a specific sms to another specific mobile phone.Like thus:

smstry.php
<?php
if($keyword)
{
//send off sms to clickatell gateway using ACCOUNT="pudding" and PASSWORD="ashton" with [phone] as destination;
}
else
{
//send off sms to Novelsoft gateway using different account and password combo with [phone] as destination;
}

How do I open a relationship with the appropriate gateway's cgi-bin in the absence of a submit button since these action are going to be carried out on a page that has no interface.
Thanks very mucho!

I think you have to use the API provided by the SMS service provider you are trying to give the SMS to/ get from.
My guess is this code (if you write it) would be fairly intense... dealing with sockets and whatnot.

You might find PHP classes that already do what you want at www.phpclasses.org or www.sf.net . (Either with the SMS or with POSTING data and manipulating the apropriate stuff)

What I'd actually look at first is if there is a SOAP service available. www.xmethods.com is a listing of soap services. Try looking for SMS service (I've seen it before). Then look at the nuSOAP PHP class.
