You forgot to add the $postvars as parameter to your function.
function openurl($url, $postvars) {
$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,$postvars);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch,CURLOPT_TIMEOUT, '3');
$content = trim(curl_exec($ch));
curl_close($ch);
echo $content;
}
$postvars = array('user' => "user123",'password' => "user#user!123",'Text' => "Test");
$sms_url ="http://remoteserver/plain";
// create a test var which we can display on screen / log
$test_url = sms_url . http_build_query($postvars);
// either send it to the browser
echo $test_url;
// or send it to your log (make sure loggin is enabled!)
error_log("CURL URL: $test_url", 0);
openurl($sms_url, $postvars);
