PHP Curl Request returning HTTP Error 411: The request must be chunked or have a content length

I'm trying to send the following CURL request in PHP. But its returning: "HTTP Error 411. The request must be chunked or have a content length."

PHP Script containing the CURL Request:

<?php
$numbers = 9999999999;
$message = "Test";
$message = urlencode($message);
$port = 80;
$url = "http://191.95.51.64/API/sendsms.aspx?loginID=myloginid&password=mypassword&mobile=".$numbers."&text=".$message."&senderid=ABCDEF&route_id=1&Unicode=1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ( $ch, CURLOPT_PORT, $port );
curl_setopt ( $ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ( $ch, CURLOPT_TIMEOUT, 20 );
curl_setopt ( $ch, CURLOPT_CONNECTTIMEOUT, 20 );
$output = curl_exec($ch);
$err = curl_error($ch);
curl_close($ch);
if ($err) {
echo $err;
} else {
echo $output;
}
?>


Output:

Length Required

HTTP Error 411. The request must be chunked or have a content length.


Since I'm new to use PHP Curl, so I couldn't be able to find out whats wrong. If anyone can briefly guide me the solution with an example, I'll be very appreciated to him. Thanks!

Since your data seems to be send as URL param,try adding content length header of zero like below:

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Length: 0));

Also instead of touching the content length header, simply try to add an empty POST body. Based on which type of HTTP server you are posting to, the behaviour differs slightly (IIS, LightHTTPD, Apache).

Empty post body similar to:

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(array()));
