4. Rename the extracted folder to “PHP”.
5. Move the PHP folder to the root of your C: drive.
6. Open the PHP folder and locate the “php.ini-development” file. Rename the file to “php.ini”.
7. Open the “php.ini” file using any text editor and make necessary configurations, such as enabling extensions or adjusting memory limits.

6. Create a new PHP file in the “htdocs” folder of your XAMPP installation directory and add some PHP code to test.
7. Open the web browser and type “localhost” in the address bar. If PHP is properly installed, you should see the output of the PHP code you wrote.
