I have the same problem and can be solved by copying file cacert.pem into my server and then insert the path of cacert file into my PHP script. In my case i put file cacert into drive C of my web server and then insert this script into my PHP File:

CURLOPT_CAINFO => "C:\cacert.pem"

So your PHP script should be like this:

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://api.telegram.org/bot332537240:MY_TOKEN/getUpdates",
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_CAINFO => "C:\cacert.pem",
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

You can download file cacert.pem from:
