Default Creating a login page in PHP

i want to make a PHP page which have username and password and this
username and password should be saved in MySql table and the page should
redirect to another page.
i want to use ODBC and PHP.
i am very new to PHP.
Can anybody having any clue for making such application?
this is my code

// Connects to your Database
$connect = odbc_connect("bhavnadb", "root", "infini") or die(odbc_error());

//This code runs if the form has been submitted
if (isset($_POST['submit'])) {

//This makes sure they did not leave any fields blank
if (!$_POST['username'] | !$_POST['pass'] | !$_POST['pass2'] ) {
die('You did not complete all of the required fields');

// checks if the username is in use
if (!get_magic_quotes_gpc()) {
$_POST['username'] = addslashes($_POST['username']);}
$usercheck = $_POST['username'];
$check = "SELECT username FROM logintable WHERE username = '$usercheck'";
$check2 = odbc_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the username '.$_POST['username'].' is already in use.');}

// this makes sure both passwords entered match
if ($_POST['pass'] != $_POST['pass2']) {
die('Your passwords did not match. ');}

// here we encrypt the password and add slashes if needed
$_POST['pass'] = md5($_POST['pass']);
if (!get_magic_quotes_gpc()) {
$_POST['pass'] = addslashes($_POST['pass']);
$_POST['username'] = addslashes($_POST['username']);}
// now we insert it into the database
$insert = "INSERT INTO logintable (username, password) VALUES ('".$_POST['username']."', '".$_POST['pass']."')";
$add_member = odbc_exec($connect,$insert);
