Now write the following document.
Save this file as "hello.php" and upload or place it in your testing folder or your web sever.
To execute this script, type something like this in your browser address bar :
http://www.yoursite.com/testfolder/hello.php
or if it's in your local site :

Adding comments on the Code
Adding comments on your php code is a good habit, this way you'll always keep track of bugs & errors that continue to show up all the time in developers browser.
Go on test it.. you'll not see those comment lines or blocks on the code.
