send string data is correct so send? I'm not able to send the request.

$header = str_pad("cccc", 4," ", STR_PAD_RIGHT);
$header .= str_pad("bbbb", 6," ", STR_PAD_RIGHT);

$url ="http://www.xxxxxxxxxx.com";

$ch                 = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $header);
$response_url   = curl_exec($ch);
$erro_curl          = curl_error($ch);
curl_close($ch);

print_r($response_url);

Not able to? Does your computer shut off? Does your internet connection reset? Do you get any errors, warnings, or notices either on the screen or in your logs? – Crontab Jan 23 at 17:43
Error: Request contains LESS THAN 15 BYTES, I am sending the other fields – user1997072 Jan 23 at 17:47
Sounds like an issue with whoever is providing the service you're trying to consume - you should probably ask them. – Crontab Jan 23 at 17:48
Aren't you supposed to send proper name value pairs in that post? rather than just some plain text – Ø Hanky Panky Ø Jan 23 at 17:49
could you give me an example? – user1997072 Jan 23 at 17:58

If you want to capture the response then you need the CURLOPT_RETURNTRANSFER option:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

Also check your post data is the correct format for what the website is expecting. Normally post data is form encoded, for that you can pass an array:

curl_setopt($ch, CURLOPT_POSTFIELDS, array('first_name' => 'john', 'last_name' => 'smith'));

You may also need to send a Content-Length, Content-Type and possibly a User-Agent header - depending on the third party.

Just try it

$header = str_pad("cccc", 4," ", STR_PAD_RIGHT);
$header .= str_pad("bbbb", 6," ", STR_PAD_RIGHT);
$header = array('test'=>$header);

add opt returntransfer

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

if you dont add this opt you dont need an echo or print like you do

print_r($response_url);

To capture the variables sent just use $_POST

$_POST['test']

Thanks!!!!! But the error continues. – user1997072 Jan 23 at 18:22
Verify if the error is in the destination url. Create a page like 'test.php' and set this page on curopt: curl_setopt($ch, CURLOPT_URL, 'localhost/test.php'); In the destination page just use <?php print_r($_POST['test']); – Gabriel Lucas Jan 23 at 18:28
I've made the two pages and it works fine. Perhaps you don't have the curl extension. In debian or ubuntu just try: $ sudo apt-get install php5-curl – Gabriel Lucas Jan 23 at 18:39
