It is easy and simple to execute PHP scripts from the windows command prompt. You just follow the below steps:
1. Open the command prompt. Click on Start button->Command Prompt.
2. In the Command Prompt, write the full path to the PHP executable(php.exe) which is followed by the full path of a script that you want to execute. You must add space in between each component. It means to navigate the command to your script location.
For example :
let you have placed PHP in C:\PHP, and your script is in C:\PHP\sample-php-script.php,
then your command line will be : C:\PHP\php.exe C:\PHP\sample-php-script.php
3. Press the enter key and your script will execute.
