Verify Login Page that either gives error when not meeting the requirement or directing it to "blogs.php" when it's a successful log in..

Hi, so this is actually my html code for the log in and sign up page and I just needed help creating a verify log in/ sign up page with exception handling. Username has to be at least 6 character long. Password has to be 6 characters long and end with a number.

For this example we must use the sessions to handle each thing in right manner.

// index.php

<?php
   session_start();
   $session = $_SESSION;
?>
