did you browse to http://localhost/Codes/filename.php ? what does your code look like? Can you post it to us?
well it is just a simple code actually.
<!-- to display variable value for single qoute, use concatenation which combine to put two strings value together-->
<!-- use single qoute is faster than use double qoute-->
<!-- to display string value for double qoute, just insert the variabe along-->
echo "Farhan $Name";
