PHP 8.4 compatibility

[andypost]

PHP 8.4 alpha2 is out and php -l passes on 13.x branch but some vendor dependencies need fixes

General function deprecation is coming https://wiki.php.net/rfc/deprecations_php_8_4

And search in vendor find vendor -name "*.php" -exec sh -c 'php -l "$1" 2>&1 | grep -v "No syntax errors detected in" || true' _ {} \; > php84-vendor.log
