3) : Write a PHP script having 3 textboxes. The first textbox should be for accepting name of the student, second for accepting name of college and third for accepting a proper greeting message. Write a function for accepting all the three parameters and generating a proper greeting message. If any of the parameters are not passed, generate the proper greeting message. (Use the concept of missing parameters)

 HTML CODE:

<html>
<body>
<form action="b3.php" method="GET">
    Enter Name of Student: <input type="text" name="stud"><br><br>
    Enter Name of College: <input type="text" name="clg"><br><br>
    Enter Greeting Message: <input type="text" name="msg"><br><br>
<input type="submit" value="submit">
</form>
</body>
</html>

 PHP CODE:

<?php
$a=$_GET['stud'];
$b=$_GET['clg'];
$c=$_GET['msg'];
/*
//if($a==NULL)
    args($a);
    /*else if( $b==NULL)
        {args($a,$c);
        }else if($c==NULL)
            {args($a,$b);
            }else
                {args($a,$b,$c);
                }
*/
args($a,$b,$c);

function args($a,$b,$c)
{  
    if($a==NULL || $b==NULL || $c==NULL)
    //if(func_num_args() < 3)
        echo "Missing argumenets";
    else
        echo $c;
}

?>
