Ubuntu Linux: How to install and setup XDebug in PHP Eclipse? [IMAGES]

PHPEclipse is a PHP development plugin for the Eclipse IDE Framework. And, XDebug is a PHP extension which provides debugging and profiling capabilities.

I am using Ubuntu Operating System. This article provides a step-by-step guide on installing and setting up XDebug in PHP Eclipse in Ubuntu.

Install XDebug in Ubuntu

Open terminal and type the following command:-

sudo apt-get install php5-xdebug

This will install XDebug.

Update xdebug.ini file

Type the following command on terminal to open xdebug.ini for edit:-

sudo gedit /etc/php5/apache2/conf.d/xdebug.ini

Add the following lines in it:-


Restart Apache

Type any one of the following command on terminal to restart apache:-

sudo /etc/init.d/apache2 restart


sudo service apache2 restart

We have now installed XDebug and made necessary settings in its ini file as well. Now, we will see how to make necessary settings for XDebug in PHP Eclipse.

Eclipse Settings

– Open Eclipse IDE
– Go to Window -> Preferences
– On left sidebar, click ‘Debug’ menu present under ‘PHP’ menu (PHP -> Debug)
– Click ‘PHP Executables‘ link as highlighted in the figure below.

PHP Executables

– A new window will popup. Add the following:-

Name = php5
Executable path = /usr/bin/php5
PHP debugger = XDebug
Leave other fields as they are (without any changes).

– Uncheck ‘Break at First Line‘ as shown in the figure below.

Break at First Line

– On left sidebar of ‘Preferences’, click ‘PHP Servers‘ menu present under ‘PHP’ menu. You will see the following screen.

PHP Servers

– If you keep your webserver URL as ‘http://localhost‘ then you can skip this step. Otherwise click on the ‘Edit’ button. Then, you will see the following screen.

– On left sidebar of Preferences, there is a search bar on top. Search for ‘browser’ and you will see the following screen. Click on ‘Web Browser‘ present under ‘General’ menu. And, you will see the following screen. Note that, here you have to select ‘Use external web browser’ and then click OK.

Debug Icon

– Click on the debug icon and you will see a dropdown menu. Click ‘Debug Configurations‘ menu from it. Then you will see the following screen.

Debug Configurations

– In the figure above, I have already performed some necessary steps. Here are they :-
– Right click on ‘PHP Web Page‘ and select ‘New’.
– Name it your new web page debug configuration. Like in the figure below, I have named my configuration as ‘magento1510’. On my web root, I have a folder/project named ‘magento1510’. I have given the File path to the index file of my project. So, it is ‘/magento1510/index.php’.

– Click ‘Apply’.

All the necessary settings have been completed. Now, you are ready to create breakpoints and start debugging.

Hope it helps. Thanks.
