You CAN list all keys in the keyring, you only have to pass an empty string ''.
<?php
$gpg = new gnupg();
$info = $gpg -> keyinfo('');
print_r($info);
?>
That's it! ;)

gnupg_keyinfo — Retorna un array con información sobre todas las llaves que coinciden con un patrón dado
$identifier, string $pattern): array
identifierEl identificador gnupg, desde una llamada a gnupg_init() o gnupg.
patternEl patrón a comprobar contra la llave.
Retorna un array con información sobre todas las llaves que coinciden con
un patrón dado o false si ocurre un error.
Ejemplo #1 Ejemplo de gnupg_keyinfo() mediante funciones
<?php
$res = gnupg_init();
$info = gnupg_keyinfo($res, 'test');
print_r($info);
?>
Ejemplo #2 Ejemplo de gnupg_keyinfo() mediante OO
<?php
$gpg = new gnupg();
$info = $gpg -> keyinfo("test");
print_r($info);

Returns an array of information blocks. An information block looks like
<?php
array (
'disabled' => <bool>,
'expired' => <bool>,
'revoked' => <bool>,
'is_secret' => <bool>,
'can_sign' => <bool>,
'can_encrypt' => <bool>,
'uids' => <array of uid blocks>,
'subkeys' => <array of subkey blocks>,
)
?>
An uid data block looks like
<?php
array (
'name' => <string>,
'comment' => <string>,
'email' => <string>,
'uid' => <string>,
'revoked' => <bool>,
'invalid' => <bool>,
)
?>
A subkey block looks like
<?php
array (
'fingerprint' => <string>,
'keyid' => <string>,
'timestamp' => <int>,
'expires' => <int>,
'is_secret' => <bool>,
'invalid' => <bool>,
'can_encrypt' => <bool>,
'can_sign' => <bool>,
'disabled' => <bool>,
'expired' => <bool>,
'revoked' => <bool>,
),
?>
It appears that listing *all* keys is not possible:
<?php
$gpg -> keyinfo(); // throws an error
$gpg -> keyinfo('*'); // is matched literally, not treated as a shell wildcard
$gpg -> keyinfo('.*'); // is matched literally, not treated as a regex wildcard
?>
This seems like a glaring omission to me.
