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-syst...1234&password=
geheim&text=Dies+ist+ein+Test&recipient=%2B4917123 45678&sender=%2B491712345678

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($absender, $empfaenger, $text, $versandroute = "")
{
global $username;
global $password;

$sms_query = sprintf("http://gateway.mobile-marketing-system.de/send_sms.php?username=%s&password=%s&text=%s&recip ient=%s&sender=%s&route=%s",
urlencode($username),
urlencode($password),
urlencode($text),
urlencode($empfaenger),
urlencode($absender),
urlencode($versandroute)
);

if(function_exists("curl_init"))
{
$ch = curl_init($sms_query);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
}
else
{
$fp = fopen($sms_query, "r");
while(!feof($fp))
{
$result .= fread($fp,4096);
}

fclose($fp);
}

return $result;
}

$result = send_sms("01748882288", "01723773477", "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
