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));
}

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"?
