MongoDB PHP Extension 1.9.0-RC1 Released

The PHP team is happy to announce that the first release candidate for version 1.9.0 of the mongodb PHP extension is now available on PECL.

Release Highlights

This release makes the extension compatible with PHP 8.

This release also ensures that all argument errors are correctly exposed as MongoDB\Driver\Exception\InvalidArgumentException on PHP 7. PHP 8 handles argument checks differently, so extra arguments or wrong types will trigger built-in errors.
