Examples of Use:

    
 
      
 
      User Login<?phprequire_once ("form.php"), $form =new form ($_server[' php_self ']);   Submit to this page $form->layout=false;                   Without using the table layout, you can comment out the differences in the results $name= $form->form_text ("userid", "userid", "username", "userid"), $passwd = $form->form_ passwd ("passwd", "passwd", "Password", "passwd"), $submit = $form->form_button ("", "submit", "Submit", "Login"); $form _item= Array ($name, $passwd, $submit); $form->createform ($form _item);? >
