GnuPG Functions
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));
}

Examples
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);
