http to SMS script help with variables 3.4

[louis-m]

I have the following script which alerts to my gsm gateway and sends sms out.
Problem is, I can't seem to set the variables from zabbix eg $1 or $to etc

Does anybody know how to set these in 3.2?

#!/usr/bin/php -q
<?php


function SendSMS()
{
// 1. Initialize  an CURL session.
$ch = curl_init();

// 2. Set parameters
$address = "http://10.1.3.100:80/sendsms?username=smsuser&password=SMSU53r&phonenumber=XXXXXXX&message=XXXXXXX&port=gsm-1.4&report=String&timeout=10";

//3.Setting the request options, including specific URL.
curl_setopt($ch,CURLOPT_URL,$address);

// 4. Execute a CURL session and get the reply.
$response = curl_exec($ch);

// 5.Release  the Curl handle and close the CURL session.
curl_close($ch);

}

SendSMS();
