Set the correct GNUPG environment, before you call gnupg_init()!

The current FPM/FastCGI/Module User must have read - if you import write - permissions on that directory. You won't get an error message, if something is not correct.
Without a correct environment, all other gnupg functions will not work as you expected.

<?php
// Enter your .gnupg environment
putenv('GNUPGHOME=/var/www/vhosts/yourdomain/.gnupg');
error_reporting(E_ALL);
$res = gnupg_init();
gnupg_seterrormode($res,GNUPG_ERROR_WARNING);
$info = gnupg_keyinfo($res, 'your-key-id');
echo "Key - Info<pre>";
var_dump($info);
echo "</pre>";
?>

Make sure home_dir option is not too many characters or else private keys fail.

You will notice that functions take a long time (seconds).

Commandline test yield error:
> gpg: can't connect to the agent: IPC connect call failed

Executing `gpg-agent --daemon --homedir /very/long/path/to/.gnupg` gave the error.
> socket name for '/very/long/path/to/.gnupg/S.gpg-agent.extra' is too long

So you must check that home_dir + '/S.gpg-agent.extra' is:
* < 107 characters on Linux
* < 104 on BSD 4.4
