title: cURL + HTTP_POST, keep getting 500 error. Has no idea?
body: <p>Okay, I want to make a HTTP_POST using cURL to a SSL site. I already imported the certificate to my server. This is my code:</p>
  
  <pre><code>$url  = "https://www.xxx.xxx";
  $post = "";# all data that going to send
  
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
  curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0'); 
  
  $exe  = curl_exec($ch);
  $getInfo = curl_getinfo($ch);
  
  if ($exe === false) {
      $output = "Error in sending";
      if (curl_error($ch)){
          $output .= "\n". curl_error($ch);
      }
  } else if($getInfo['http_code'] != 777){
      $output = "No data returned. Error: " . $getInfo['http_code'];
      if (curl_error($ch)){
          $output .= "\n". curl_error($ch);
      }
  }
  
  curl_close($ch);
  
  echo $output;
  </code></pre>
  
  <p>It keep returned "500". Based on w3schools, 500 means Internal Server Error. Is my server having problem? How to solve/troubleshoot this?</p>
