php trouble

when i run this as admin.php and hit submit my site goes to www.mysite.com/$_SERVER[PHP_SELF] instead of checking itself, i just learned php today and any help with this would be great.

<?php if ($_POST['user'] == 'admin' && $_POST['pass'] == 'anahacker') print 'LOGIN CORRECT, DATA WILL BE ADDED SOON'; else print ' <form action="$_SERVER[PHP_SELF]" method="post"> ADMIN:<input type="text" value="" name="user" /> <br /> PASS:<input type="password" value="" name="pass" /> <br /> <input type="submit" value="submit" /> </form> '; ?>

Since you're using echo() to produce HTML source, you're going to want to put backslashes in front of the quotation marks (e.g. <input type=\"text\").
