IntelliJ IDEA 2019.1 Help

Browser Debugging Extensions

In order to start debugging, you first need to activate the debugger engine on the server. To do this, you need to set a special GET/POST or COOKIE parameter (see the Xdebug and Zend Debugger official documentation for details). While you can do it manually, it is more convenient to use a browser extension, which lets you enable the debugger with a single click.

The following table lists the available debugging extensions.

Chrome

Firefox

Internet Explorer

Safari

Opera

Xdebug

Xdebug Helper

Xdebug Helper or Xdebug-ext

PhpStorm bookmarklets generator

Xdebug Toggler

Xdebug launcher

Zend Debugger

zDebug or Zend Debugger Toolbar

Zend Debugger Toolbar

Z-Ray for Zend Server version 7 or later. PhpStorm bookmarklets generator otherwise.

Configure Xdebug Helper for Chrome

  1. Install the Xdebug helper extension for Chrome from the Chrome Web Store.

  2. In IntelliJ IDEA, enable listening to incoming debug connections by either clicking the Start Listening for PHP Debug Connections button on the toolbar or selecting Run | Start Listening for PHP Debug Connections

  3. Initiate connection from the browser side. Click the Xdebug Helper icon on the browser toolbar to initiate a debugging, profiling or tracing session:
