In these instances you could rely on != behaviour instead of ==
behaviour, like this:
<?php
if ($challenge_password_hash != $stored_password_hash) {
echo 'Stay out! This club is for members only!';
} else {
echo 'Welcome to the club!';
}
?>
or, better yet:
<?php
if ($challenge_password_hash != $stored_password_hash) {
echo 'Stay out! This club is for members only!';
exit;
}
echo 'Welcome to the club!';
// Lots of code here that just saved itself another indent in my IDE

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
