      1. Verify that you get ZERO matches, that means that there aren't remaining cases.
      2. Using moodle-docker (or any >= PHP7.4 RC4 installation) install phpunit (init.php).
      3. Verify that there isn't any PHP notice/warning related with adodb, google, horde, ltiprovider stuff. (Be warned that there may be lots of notices/warnings/errors, here we are only interested in the adodb, google, horde, ltiprovider ones).
      4. Run phpunit (with that PHP7.4 version).
      5. Verify that there isn't any PHP notice/warning related with adodb, google, horde, ltiprovider. (Be warned that there are lots of notices/warning/errors and failures, here we are only interested in the adodb, google, horde, ltiprovider ones

    Description

      We have glued 4 libraries here because changes are minimal (1-line change) + readme documenting it.

      In none of the case we are upgrading the libraries because 1) or the patch has not been merged upstream or 2) the libraries are so outdated that there isn't a clear upgrade/replacement for them.

      About the case 2) above, I've created MDL-67033, because we need to decide urgently about some of them.

      These are the 4 changes, related to php74 curly braces, that we need to fix. As commented above, the corresponding readme files will be updated to include a call to this (or to the upstream pull request, if there is any).

      lib/adodb/drivers/adodb-oci8po.inc.php:123:			$c = $sql{$i};
      lib/google/src/Google/Utils.php:65:      $ordinalValue = ord($str{$ret});
      lib/horde/framework/Horde/Crypt/Blowfish/Php/Base.php:331:                $data = $data << 8 | ord($key{$k});
      lib/ltiprovider/src/OAuth/OAuthSignatureMethod.php:59:            $result |= ord($built{$i}) ^ ord($signature{$i});
