How to do a POST request

This example shows how to do a simple POST request to another webserver by using a socket connection.
function post_request($url, $data, $referer='') { // Convert the data array into URL Parameters like a=b&foo=bar etc. $data = http_build_query($data); // parse the given URL $url = parse_url($url); if ($url['scheme'] != 'http') { die('Error: Only HTTP request are supported !'); } // extract host and path: $host = $url['host']; $path = $url['path']; // open a socket connection on port 80 - timeout: 30 sec $fp = fsockopen($host, 80, $errno, $errstr, 30); if ($fp){ // send the request headers: fputs($fp, "POST $path HTTP/1.1\r\n"); fputs($fp, "Host: $host\r\n"); if ($referer != '') fputs($fp, "Referer: $referer\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ". strlen($data) ."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $data); $result = ''; while(!feof($fp)) { // receive the results of the request $result .= fgets($fp, 128); } } else { return array( 'status' => 'err', 'error' => "$errstr ($errno)" ); } // close the socket connection: fclose($fp); // split the result header from the content $result = explode("\r\n\r\n", $result, 2); $header = isset($result[0]) ? $result[0] : ''; $content = isset($result[1]) ? $result[1] : ''; // return as structured array: return array( 'status' => 'ok', 'header' => $header, 'content' => $content ); } //Example: //============================================== // Submit those variables to the server $post_data = array( 'test' => 'foobar', 'okay' => 'yes', 'number' => 2 ); // Send a request to example.com $result = post_request('http://www.example.com/', $post_data); if ($result['status'] == 'ok'){ // Print headers echo $result['header']; echo '<hr />'; // print the result of the whole request: echo $result['content']; } else { echo 'A error occured: ' . $result['error']; }
