You can see who made the signature by checking its fingerprint:
<?php
$res = gnupg_init();
$info = gnupg_verify($res,$signed_text,$signature);
if($info !== false){
$fingerprint = $info['fingerprint'];
var_dump(gnupg_keyinfo($res, $fingerprint));
}

( resource
$identifier
, string $signed_text
, string $signature
[, string &$plaintext
] )
Verifies the given signed_text and returns information about the
signature.

-
signed_text -
The signed text.
-
signature -
The signature. To verify a clearsigned text, set signature to

Example #1 Procedural gnupg_verify() example
<?php
$plaintext = "";
$res = gnupg_init();
// clearsigned
$info = gnupg_verify($res,$signed_text,false,$plaintext);
print_r($info);
// detached signature
$info = gnupg_verify($res,$signed_text,$signature);
print_r($info);
?>
Example #2 OO gnupg_verify() example
<?php
$plaintext = "";
$gpg = new gnupg();
// clearsigned
$info = $gpg -> verify($signed_text,false,$plaintext);
print_r($info);
// detached signature
$info = $gpg -> verify($signed_text,$signature);
print_r($info);
?>

Where can I see description of result array?
I've got
Array
(
[0] => Array
(
[fingerprint] => 9BF78012F700B345827346E1EFA3026F01404358
[validity] => 4
[timestamp] => 1643100153
[status] => 0
[summary] => 3
)
)
But what does "status" mean? What is "validity"? What is "summary"?
