This "classic" W3C WebDriver client implementation is based on the php-webdriver project by Justin Bishop. Originally conceived as a thin wrapper around the JSON Wire Protocol, the client has been refactored to work with the W3C WebDriver Protocol, with some fallback/emulation for older drivers. We'll continue to track changes to the specs but there are no immediate plans to add WebDriver-BiDi support.

If you are starting a new project (using PHP 7.3 or above), you should consider using Meta/Facebook's completely rewritten (and more actively maintained) php-webdriver.

Notes

• The 1.x branch is up-to-date with the legacy Selenium 2 JSON Wire Protocol.
