Sendgrid Azure PHP

Question

I am a newbie to php, azure, and sendgrid.

here is some code I found that I am trying to use for the html form.

Answer 1

As you hadn’t defined $curl before setting parameters using curl_setopt, and here is a code sample on SendGrid code examples page, please try it:

 $user,
    'api_key'   => $pass,
    'to'        => 'example3@sendgrid.com',
    'subject'   => 'testing from curl',
    'html'      => 'testing body',
    'text'      => 'testing body',
    'from'      => 'example@sendgrid.com',
  );


$request =  $url.'api/mail.send.json';

// Generate curl request
$session = curl_init($request);
// Tell curl to use HTTP POST
curl_setopt ($session, CURLOPT_POST, true);
// Tell curl that this is the body of the POST
curl_setopt ($session, CURLOPT_POSTFIELDS, $params);
// Tell curl not to return headers, but do return the response
curl_setopt($session, CURLOPT_HEADER, false);
// Tell PHP not to use SSLv3 (instead opting for TLS)
curl_setopt($session, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// obtain response
$response = curl_exec($session);
curl_close($session);

// print everything out
print_r($response);

?>

--Update--

If you get error message as not defined constant CURL_SSLVERSION_TLSv1_2, we can directly set integer variable to CURLOPT_SSLVERSION. We can find details in http://php.net/manual/en/function.curl-setopt.php:

One of CURL_SSLVERSION_DEFAULT (0), CURL_SSLVERSION_TLSv1 (1), CURL_SSLVERSION_SSLv2 (2), CURL_SSLVERSION_SSLv3 (3), CURL_SSLVERSION_TLSv1_0 (4), CURL_SSLVERSION_TLSv1_1 (5) or CURL_SSLVERSION_TLSv1_2 (6).

set as: curl_setopt($session, CURLOPT_SSLVERSION, 6);

And I have to set an additional option :

curl_setopt($session, CURLOPT_SSL_VERIFYPEER, false);

so that I can succeed to set my request to SendGrid Server.
