Php without break;

Question

What happened to my switch? Now the result:

< more
> less
= equality
!= no't equality 

As it should be:

< more
= equality

<?php
$page = 99;

    switch ($page)
    {
        case $page < 121:
            echo '< more <br/>';
        case $page > 123:
            echo '> less <br/>';
        case $page == 99:
            echo '= equality <br/>';
        case $page != 99:
            echo '!= no\'t equality <br/>';
    }   
    ?>
