Also it is good practice to have your post information in one page. So with the example about
Code:
<html>
<body>
<form action="welcome.php" method="POST">
Enter your name: <input type="text" name="name" />
Enter your age: <input type="text" name="age" />
<input type="submit" />
</form>
</body>
</html>
I think it should be
Code:
<html>
<body>
<?
if (isset($_POST['Submit']))
{
    print $_POST['name'];
    print $_POST['age'];
}
else
{
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="POST">
Enter your name: <input type="text" name="name" />
Enter your age: <input type="text" name="age" />
<input type="submit" />
</form>
<?php
}
?>
</body>
</html>
And maybe down the bottom you should have included something about coding standards. It is important to get good coding standards before you start out. For example using curly brackert ({ }) instead of not.

Like I mentioned in the first post, this whole tutorial is compiled from all the PHP tutorials on W3Schools, I just thought I'd share it with you guys..
