•    'c'.$i  ->  become c1 at 1st iteration and c2,c3,c4 ...and so on.

     <?php

            if(isset($_POST['nos']))
               $nos = $_POST['nos'];

            $techie=0;
            for($i=1;$i<= $nos;$i++)
                 {
                    $techie = $_POST['c'.$i] ;
                     echo "$techie";
