webinspector-php

A PHP Debugger interface using XDebug and WebKit's WebInspector

I always have though that WebInspector is a great graphical debugging interface. Since PHP is so highly deployed I though it could make a great combination to use it to debug PHP. FirePHP and ChromePHP try to bridge the gap between WebInspector and PHP but neither allow you to step thru the code or inspect variables. This development does exactly that.

It has been develop thanks to the following great open-source projects:

What works:

  • Code stepping
  • Breakpoints
  • Variable inspection

What's missing:

  • Stack traces
  • Console output
  • Expression evaluation
  • More documentation
  • Watched Expressions

How to use?

Requirements:

To run this tool you require of:

  • A Webserver (I use Apache but it should work with any PHP supported webserver: IIS, nginx, Lighttpd, etc)
  • PHP 5.2 or better
  • XDebug extension for PHP
  • NodeJS with the modules: connect, websocket & xml2js
  • Chrome WebBrowser

To compile the code you additionally will need:

  • HaXe 2.10
  • HaXe libraries:
    • nodejs_std
    • nodejs_externs

How to install?:

Configure your Webserver with PHP, if you use a Debian based linux distro this is very simple with aptitude:

# sudo apt-get install apache2 php5 libapache2-mod-php5

Install and configure XDebug on your webserver:

# sudo apt-get install php5-xdebug

After installing, we need to customize the XDebug configuration. Append the following lines to /etc/php5/conf.d/xdebug.ini:

[xdebug]
; enable debugger
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_port=9000
; You can uncomment the following line to start the debugger automatically when navigating any PHP page.
; xdebug.remote_autostart = 1

Restart your webserver so it will take the new configuration:

# sudo /etc/init.d/apache2 restart

Now install NodeJS, for that go to http://nodejs.org/download/ and download the package for your distro. You can find instructions for almost any platform. If you use linux I'll recommend to also check:

https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager

Get the debugServer JavaScript compiled source from GitHub:

# mkdir ~/debugServer
# cd ~/debugServer
# wget https://raw.github.com/igwtech/webinspector-php/master/NodeMain.js

Install the node modules required using the Node Package Manager (npm):

# cd ~/debugServer
# npm install connect websocket xml2js

How to load a project into the debugger?:

Run the debugServer with NodeJS:

# cd ~/debugServer
# node NodeMain.js

The debugServer will create a listening socket on port 9000 for XDebug to connect to and a WebServer on port 8080 where the WebInspector interface will be served.

Open a Chrome window and point it to:

http://localhost:8080/devtools/devtools.html?ws=localhost:8080/debugger

Now open another Chrome window and point it to your PHP site on your webserver passing the XDEBUG Session parameter, for example:

http://localhost/phpsite/index.php?XDEBUG_SESSION_START=foobar

You will get an automatic breakpoint on your WebInspector Browser window with the PHP source code.

Profit!

Note: You need to open/reload the browser windows in the order mentioned to start a debugging session on WebInspector.

How to compile?:

Install Haxe 2.10, and using haxelib install the dependencies:

# sudo haxelib install nodejs_std
# sudo haxelib install nodejs_externs

A HXML is included in the code, download it using Git and compile simple by running:

# haxe debugServer.hxml
