Xdebug & Zend Debugger bookmarklets generator for PhpStorm
PhpStorm supports debugging with both Xdebug & Zend Debugger. The debugger is activated from the browser side by setting a special parameter. While you can do that manually, it is much more convenient to use a special tool such as a browser toolbar (check your browser extensions list) or bookmarklets. Browser bookmarklets for both debuggers can be generated on this page.
