Question

This is my cURL POST function:

public function curlPost($url, $data)
{
    $fields = '';

    foreach($data as $key => $value) { 
      $fields .= $key . '=' . $value . '&'; 
    }

    rtrim($fields, '&');

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, count($data));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

    $result = curl_exec($ch);
    $info   = curl_getinfo($ch);

    curl_close($ch);
}

$this->curlPost('remoteServer', array(data));

How do I read the POST on the remote server?

The remote server is using PHP… but what var in $_POST[] should I read

for e.g:- $_POST['fields'] or $_POST['result']

Answer 1

You code works but i’ll advice you to add 2 other things

A. CURLOPT_FOLLOWLOCATION because of HTTP 302

 curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

B. return in case you need to output the result

return $result ;

Example

function curlPost($url, $data) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    $result = curl_exec($ch);
    $info = curl_getinfo($ch);
    curl_close($ch);
    return $result;
}

print(curlPost("http://yahoo.com", array()));

Another Example

    print(curlPost("http://your_SITE", array("greeting"=>"Hello World")));

To read your post you can use

 print($_REQUEST['greeting']);

or

 print($_POST['greeting']);
