*/
function post_json_data($url, $data_string) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json; charset=utf-8',
        'Content-Length: ' . strlen($data_string))
    );
    ob_start();
    curl_exec($ch);
    $return_content = ob_get_contents();
    ob_end_clean();
    $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    return array('code'=>$return_code, 'result'=>$return_content);
}
$arr = array('a'=>'555','b'=>56454564);
dump(post_json_data('http://192.168.211.1/html/dump.php',json_encode($arr)));

$content = file_get_contents('php://input');
