cURL firestarter help needed

[Steffen Mutter]

Hi there!

I just want to get this http thing into a dynamic scipt using cURL which -
as you might have guessed - I never used before and documentation I found
so far is quite unuseful for me...

So let's get to the point:
If I put this into the browser of choice:

http://gateway.mobile-marketing-system.de/send_sms.php?username=KU-1234&password=

geheim&text=Die s+ist+ein+Test& recipient=%2B49 1712345678&send er=%2B491712345 678

everything works fine.

Nor here's a script I got from this website, put my registration data in
and it does - nothing. cURL support is turned on - but maybe you might be
able to tell me how to use this script. (There was no further
documentation included)

<?php

$username = "XXXXX"; // hier bitte Ihre Kunden-ID eintragen
$password = "XXXXX"; // hier bitte das in den Einstellungen definierte Password

function send_sms($absen der, $empfaenger, $text, $versandroute = "")
{
global $username;
global $password;

$sms_query = sprintf("http://gateway.mobile-marketing-system.de/send_sms.php?us ername=%s&passw ord=%s&text=%s& recipient=%s&se nder=%s&route=% s",
urlencode($user name),
urlencode($pass word),
urlencode($text ),
urlencode($empf aenger),
urlencode($abse nder),
urlencode($vers androute)
);

if(function_exi sts("curl_init" ))
{
$ch = curl_init($sms_ query);
curl_setopt($ch , CURLOPT_RETURNT RANSFER, 1);
$result = curl_exec($ch);
curl_close($ch) ;
}
else
{
$fp = fopen($sms_quer y, "r");
while(!feof($fp ))
{
$result .= fread($fp,4096) ;
}

fclose($fp);
}

return $result;
}

$result = send_sms("01748 882288", "0172377347 7", "Dies ist ein Text", "route2");

?>

All I want is to send a POST type message to a remote URL which contains
the same as in the http-request I posted above. Any help or a link to
useful dokumentation with examples hoh to use cURL highly appreciated.

Thanks,
Steffen
