if ($flag) {
    header("Location:1.php");
    exit(0);
}
else {
    header("Location:2.php");
    exit(0);
}

For the second question you can either use Javascript (not all users have javascript enabled, so it's not guaranteed to work), and check the value of the fields, or hava a serversite check and redirect the user with header, as above.

I think this is the best way because you have not to fight with the possible lost of the $_POST[]

if($flag)
   require '1.php';
else 
   require '2.php';

For form validations, you need to use javascript.

 <head>
   <script type="text/javascript">

     function validateForm()
     {
         // Conditions to check whether the text box is empty or not.
     }

   </script>
 </head>

<form action="index.php" method="post">
<input type="button" name ="submit" value="comfirm" onsubmit = " return validateForm() ">

If validateForm() returns true, then only on button click it goes to index.php

Try this:

if($flag) {
  //go to 1.php
  header("Location: 1.php");
  exit(0);
}
else  {
  //go to 2.php
  header("Location: 2.php");
  exit(0);
}

And for the second part you might want to use some client side script to double check the inputs and a server side script to double double check them

I like to use META refresh..

<meta http-equiv="refresh" content="3;url=somewhere.php">

3 is the number in seconds before it redirects the viewer
