Using PHP to Execute cURL to send Push Notification - php

Question

I'm attempting to send a cURL command to send a push notification. I'm pretty new to cURL and cannot seem to get the command to run.
Here is the cURL command line:
curl --header "Authorization: key=AAAAVD27CWY:APA91bE7YdKYiqTmQhErf0E3gm8lbgNt2KP5-xPQf83V7m8eKsa0ljktOLiGyzzrP0uxVNBHC6cyuJAPejkTyNl1DnoxcajesLvGXIzq3YR1l-wiFvoivRmIUkDvThTsKCJkZMomhEPp" --header Content-Type:"application/json" https://android.googleapis.com/gcm/send -d "{\"registration_ids\":[\"fr1l051Pczw:APA91bGkyuA6iKMP6oICJ8NweijQpWTWGuo-inqvpF5-Mety0D7oL_ppvevKKdWPxIo7ev_v5sAWbprk7pEg8kz3cNCivipL9RCR3XlA1caBtahsRtnANZpaU-KYnsdjcGY3Q51xN1ny\"]}"
and here is the PHP cURL I'm trying to execute:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"registration_ids\":[\"fr1l051Pczw:APA91bGkyuA6iKMP6oICJ8NweijQpWTWGuo-inqvpF5-Mety0D7oL_ppvevKKdWPxIo7ev_v5sAWbprk7pEg8kz3cNCivipL9RCR3XlA1caBtahsRtnANZpaU-KYnsdjcGY3Q51xN1ny\"]}");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Authorization: key=AAAAVD27CWY:APA91bE7YdKYiqTmQhErf0E3gm8lbgNt2KP5-xPQf83V7m8eKsa0ljktOLiGyzzrP0uxVNBHC6cyuJAPejkTyNl1DnoxcajesLvGXIzq3YR1l-wiFvoivRmIUkDvThTsKCJkZMomhEPp";
$headers[] = "Content-Type: \"application/json\"";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
I'm running this with Google's Firebase Cloud Messaging.
I can execute the command on my server, so I know at least that works.
Running UBUNTU 16.04 and Apache.
I am running SSL on the server and have tried adding:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
Still no luck.
