PHP cURL not working and not showing any errors

Question

Below is the code I have written. But its not showing anything on my screen. Am I missing anything?

error_reporting(E_ALL);
   ini_set("display_errors", 1);

            $reservation_obj['source'] = "website";
            $reservation_obj['location_code'] = "test";
            $reservation_obj['start_date'] = "2010-06-01 19:00";
            $reservation_obj['end_date'] = "2010-06-04 13:50";
            $reservation_obj['action'] = "get_quotes";

            $json = json_encode($reservation_obj);

  $ch = curl_init();

  curl_setopt($ch,CURLOPT_URL,"https://myserver/test.php");
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
  curl_setopt($ch,CURLOPT_HEADER, true);
  curl_setopt($ch,CURLOPT_HTTPHEADER, array('Content-Type: text/json', 'Content-length: '.strlen($json)));
  curl_setopt($ch,CURLOPT_POST, true);

  curl_setopt($ch,CURLOPT_POSTFIELDS, $json);
  curl_setopt($ch,CURLOPT_VERBOSE, false);

  curl_setopt($ch,CURLOPT_SSLCERT,getcwd()."key/test_services.pem");
  curl_setopt($ch,CURLOPT_SSLCERTTYPE, "PEM");

  curl_setopt($ch,CURLOPT_SSLKEY,getcwd()."key/test_services.p12");
  curl_setopt($ch,CURLOPT_SSLKEYTYPE, "P12");

  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch,CURLOPT_SSLVERSION, 3);

  $output=curl_exec($ch);

  curl_close($ch);

  print_r($output);

This is what I got on printing

echo "<pre>";
  var_dump(curl_getinfo($ch));
  echo "</pre>";

Below is the output I got. And I server need the ssl certificate thats why I added the ssl things. If am wrong please help me.

array(26) {
  ["url"]=>
  string(68) "https://myserver/test.php"
  ["content_type"]=>
  NULL
  ["http_code"]=>
  int(0)
  ["header_size"]=>
  int(0)

  int(443)
  ["local_ip"]=>
  string(12) "192.168.1.75"
  ["local_port"]=>
  int(36492)
}

After removing it I got this:

}

print_r(curl_getinfo($ch)); after exec and check what you get http code. if you not verifying SSL why you added SSL code like version etc. — Rakesh Sharma

Hi, I have printed the stuffs you asked. Please check it.. and let me know your thoughts. — Gladson

you got ["http_code"]=> int(0) means not working it should be 200 for correct — Rakesh Sharma

try to remove curl_setopt($ch,CURLOPT_SSLCERT,getcwd()."key/test_services.pem"); curl_setopt($ch,CURLOPT_SSLCERTTYPE, "PEM"); let me know result what you get? curl_setopt($ch,CURLOPT_SSLKEY,getcwd()."key/test_services.p12"); curl_setopt($ch,CURLOPT_SSLKEYTYPE, "P12"); curl_setopt($ch,CURLOPT_SSLVERSION, 3); — Rakesh Sharma

Try this after you curl_exec command and before curl_close. That should print any errors.

if($errno = curl_errno($ch)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
}

Warning: curl_getinfo() expects parameter 1 to be resource, string given in /var/www/html/api/first.php on line 47 NULL

There is no curl_getinfo() in my answer. Also you must run all curl_function before you call curl_close($ch). That's probably your problem.

Tali Luvhengo Over a year ago

So curl is not printing errors. You need resolve the SSL issue. The server you are talking to is probably running different ssl version than 3. Try another SSL version. like 2 curl_setopt($ch, CURLOPT_SSLVERSION, 2);
