Can u please suggest for how to work in wamp server?

Answer 1

your project folder is www and go to localhost on your browser to find and execute your project like
in www -> create folder hello
in the folder hello -> create index.php file (with standard conf it's the first file read)
in the file write <?php echo ("Hello World!!!"); ?>
go to localhost and click on the hello project
if all work, you get a White screen with printed "hello world!!!"
