when dealing with curl always start by debugging errors, which you can enable like
$result = curl_exec($ch);
if (curl_errno($ch)) {
$error_msg = curl_error($ch);
echo $error_msg;
}
and as you mentioned in comment, you received below error after adding above code:
could not load PEM client certificate, OpenSSL error error:02001002:system library:fopen:No such file or directory, (no key found, wrong pass phrase, or wrong file format?)
It clearly indicate it can't find your certificate files, update path to those files in your call , like if your certificates are in directory /var/www/certificate/, your code would be
curl_setopt($ch, CURLOPT_SSLCERT, '/var/www/certificate/crt.crt');
curl_setopt($ch, CURLOPT_SSLKEY, '/var/www/certificate/key.key');
and make sure cert files are readable by setting proper permissions.
p.s you can also use Laravel helpers to get the path
base_path(); // '/var/www/mysite'
app_path(); // '/var/www/mysite/app'
storage_path(); // '/var/www/mysite/storage'
so you call will contain like
curl_setopt($ch, CURLOPT_SSLCERT, base_path().'/certificate/crt.crt');
curl_setopt($ch, CURLOPT_SSLKEY, base_path().'/certificate/key.key');
