Subject: [NFC] - Compatibility for PHP-7.4/PHP-8
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=517bd5a9099f534e2c6402cc9abe8696df0c01d0;p=civicrm-core.git

[NFC] - Compatibility for PHP-7.4/PHP-8

There are a few more leftovers under vendor and packages: `find . -name "*.php" -exec php -l {} \; | grep -v "No"`. Not sure how to deal with that.
