First of all, we need to configure XDebug. Here we are going to configure it on VSCode.

Follow these steps to configure XDebug in VSCode:

• Save your project as a workspace in VSCode and remember the name you give here. This name will be used when we configure debugger.

• Install PHP debugger extension in VSCode.

• Now we need to Install xdebug on our system as well. Go to this link https://xdebug.org/docs/install

• After successful installation of XDebug on your system, create a test.php on the root of your PHP project and add phpinfo() inside that file.

• Access that file in your browser. You will see your phpinfo like this

• Select everything ( ctrl/cmd + a ) you see on this page and add it to xdebug wizard https://xdebug.org/wizard

  

• Follow the xdebug wizard instructions after clicking on the `Analys my phpinfo() output` button.

  

• After completing all xdebug wizard instructions steps, add these two lines to your php.ini:
  xdebug.client_host = localhost xdebug.client_port = 9003

• Restart Apache/Sevrver( MAMP, XAMP, WAMP )

• Now go back to your VSCode project.

• Go to debugger and create a launch.json

• Now it's time to add a breakpoint from where you want to start debugging. So click on the line number to set a breakpoint. You will see a red ( depends on your theme ) dot.
