Debugging with Zend vs Xdebug: What is the difference? David Created January 06, 2011 14:49 It is not clear to me why these alternatives exists. Reasons why we might prefer one over the other? Thank you.
Both are just a PHP debugging engine implementation. Both have own quirks and bugs, but Zend debugger comes directly from "Zend, the PHP company" and usually works better than xDebug.
Hello David,
Also you cannot use XDebug with Zend Optimizer.
