Xdebug is a handy tool to debug PHP based project and work seamlessly with NetBeans and eclipse IDE. There are add-on and plugins available for Notepad++ and Sublime editor to enable Xdebug based debugging.

Xdebug download

Let’s start the process with downloading the Xdebug right for your PHP version. You may need to know which PHP version you are on, weather it is Thread Safe or Non Thread Safe and are you using 32bit or 64bit PHP version. Based on these three points you can decide which Xdebug version you need to download. Phpinfo() function would provide you all necessary information about your PHP version and so on. Visit Xdebug download page to download the plugin.

If you find it hard to gather all the details like PHP version, TSF or Non TSF and 32bit/64bit then there is an easier way available. It is known as custom installation instructions offered by Xdebug which suggests which version of plugin you should download based on your phpinfo() output.

Once you past your phpinfo content, you may receive output something like shown in image below. Please do note I already have installed and configured Xdebug on my machine.

It reads every required piece of information from your phpinfo() output and suggests you a plugin version that you need to download and configure on your machine.

Once you have matching version of Xdebug downloaded into your machine, now is the time to place the plugin to required directory and configure the php.ini file.

Configure Xdebug

First find the PHP directory on your WAMP/XAMPP setup. You need to locate the ext directory underneath. Once you located the directory past the downloaded Xdebug dll file into the ext directory. I am using custom Apache x64bit, PHP x64bit and MySQL setup on top of Windows 7 x64. And my PHP directory located under the C: drive. Following snapshot shows the ext directory under my setup.

Now open the php.ini file for further configuration. I prefer to use Notepad++ for configuration files as it offer flexibility in search, replace and syntax coloring. You need to add following lines at the end of your php.ini files.


You need to change C:phpext this line with you actual path to ext directory under PHP and plugin name php_xdebug-2.4.0-7.0-vc14-x86_64.dll with your downloaded plugin file name.

Once done, restart your apache server/service and check phpinfo() output and look for xdebug. If configuration was proper you should be able to see the output.

If you already have added php to your environment variable then this process will be much easier. Open command prompt (cmd) on your machine and fire-up php -v this will display PHP version along with Xdebug version. Like below.
