What is the difference between these two examples?
Both works fine for me.
1. if ($_POST['submit'] == 'Login') {
...
...
}
2. if (isset($_POST['submit']) {
...
...
}

One is checking if $_POST contains a specific value, the other just checks to see if it contains a value. If $_POST['submit'] contains 'foo' is ISSET. Make sense?
Maybe a daft question but why would you like to check for a specific value?
Can you give an example when this is a good thing to do?
