    • support for member functions
  • memory allocation

  • protection for infinite recursions

  • profiling information for PHP scripts

  • code coverages analysis

  • capabilities to debug your scripts interactively with a debugger front-end

Setting up XDebug.

Open your XAMPP panel and click the Config button, a menu will appear.

Click the fourth option in the menu that says PHP (php.ini).

This should open the 'php.ini' file in notepad or your default text editor.

Now add the following code block at the end of your php.ini file.

[XDebug]
xdebug.remote_enable = on  
xdebug.remote_host="127.0.0.1"  
xdebug.remote_port=9000  
xdebug.remote_handler=dbgp  
xdebug.profiler_output_dir="\xampp\tmp"  
[PHP_XDEBUG]
zend_extension="C:\XAMPP\php\ext\php_xdebug.dll"  

Now you can restart Apache, After Apache restarts you will see Xdebug in action.

Enjoy. Happy Coding!
