Zend Debugger is a full-featured php debugger engine, an interactive tool that helps you debug PHP scripts. It works with a production and/or development web server and allows you to debug your scripts locally or remotely, from an IDE or the console. To get the debugger to work you need to install the debugger engine to run in the PHP interpreter (server part), and configure the debugger client to communicate with the engine.
