a)Open Notepad. (File>>All Programs>>Accessories>>Notepad).

b)Then type   (<?php echo “Hello World!”; ?>)c)Save this file as whatever name you want.

.When saving files in Windows Notepad, wrap the filename in double quotations so that Notepad doesn’t add .txt to the end of the filename. Notice in the image that the file hello world.php has ” ” around it. Without the quotation marks Notepad would have saved the file as hello world.php.txt
