示例 #1 Procedural gnupg_geterrorinfo() example

    ?>

以上示例会输出：

      ["gpgme_code"]=>
      int(0)
      ["gpgme_source"]=>

    // error call
    $gpg->decrypt('abc');

    ?>

以上示例会输出：

    array(4) {
      ["generic_message"]=>
      string(14) "decrypt failed"
      ["gpgme_code"]=>
      int(117440570)
