You can simply check this by isset()

Try this code:

if(isset($_REQUEST['fname'])){
 $name = $_REQUEST['fname']; 
 echo $name; 
}

Yes, $_REQUEST variable also contains $_POST. But the way you are checking it is incorrect.

It can be done using isset() to check its existence:

if(isset($_REQUEST['fname'])){
    $name = $_REQUEST['fname']; 
    echo $name; 
}

It's not the REQUEST array you have to use! It's POST since your method of the form is post:

like this:

$_POST['fname']

And i think you want to check if it is set like this:

if(isset($_POST['fname']))
