am writing a php file for my sms site to send message so that the output would give something like the one above. Here is a look at my code:

if i try sending sms through it i get something like, message not sent. what did i do wrong? please help

Exactly which error do you get? There are a few defined in the code above, and a load more that could be generated by your web browser, PHP or Apache. Please copy and paste the exact error you get into a new post so we can troubleshoot better.

From what I see the API are trying to get your data or content you are sending by the GET parameters appended to the url. Maybe you can try curl setopt to GET method?

it only tells me message not sent.

That error is coming from another file, so I can only take a random guess, but it looks like this line:

$response_string = curl_exec($ch);

Doesn't set $response_string equal to 200, which means you have got some of the server data wrong near the top of that file, so it can't access the server, or gets an error code from it.

Where exactly are you setting the $port variable you're passing to curlopt as CURLOPT_PORT? Also, its not certain that a POST will work if the spec says you should GET.

@rvalkass, what do i replace it with? do tell me.Thanks@nooc9, i dont really understand

You'll need to change these lines, or make sure they are correct:

curl_setopt($ch, CURLOPT_URL, $url);	curl_setopt ($ch, CURLOPT_PORT, $port);	curl_setopt ($ch, CURLOPT_POST, 1);	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

You'll therefore also need to check the values of $url and $port and make sure they are correct.

This is the API code which you told us from the sms provider.

http://forums.xisto.com/no_longer_exists/

From this particular line it told us that the API is expecting a GET method instead of a POST. However in your script you coded it to be POST instead.

curl_setopt ($ch, CURLOPT_POST, 1);

Trying change to CURLOPT_GET and see what happens.

Here is an example function that should work..

function frihostSend($user, $passw, $to, $from, $data, $type='text', $port=80){	$ch = curl_init();		$content = urlencode($data);		// construct the url call	curl_setopt($ch, CURLOPT_URL,		"http://forums.xisto.com/no_longer_exists/;		."user=$user&password=$passw&to=$to&from=$from&content=$content&content_type=$type");			curl_setopt ($ch, CURLOPT_PORT, $port);	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);	// uncomment the below to support redirection	//curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);	//curl_setopt($ch, CURLOPT_MAXREDIRS,1);		$response = curl_exec($ch);	$code = curl_getinfo($ch)['http_code'];		curl_close($ch);		return array($code,$response); // return an array with the results}
