$curl = curl_init();
curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_URL, $api_endpoint);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $nvp_string);
$result = curl_exec($curl);
if(curl_exec($curl) === false)
{
   echo 'Curl error: ' . curl_error($curl);
}

You should get the actual error code with

echo curl_errno($curl); // It might display a '59'

Find '59' at https://curl.haxx.se/libcurl/c/libcurl-errors.html which is CURLE_SSL_CIPHER (59) and read about the error and then research how to fix it.

Possible fix

Based on https://stackoverflow.com/a/4073567 you should try:

curl_setopt($curl, CURLOPT_SSLVERSION, 3);

This is potentially dangerous though, since it forces SSL3.

  • I commented with the same value but it could (should ?) be 6 (CURL_SSLVERSION_TLSv1_2, this is TLS v1.2 – Loenix Mar 15 '16 at 13:35
  • @Loenix I wonder if OP's PHP/cURL/openSSL version doesn't support the latest protocol. Maybe PayPal's API requirements are too high for PHP 5.4? – MonkeyZeus Mar 15 '16 at 13:38
