note 104870 added to keyword.class

I wasn't taught correctly in my school, but, can you use the class with the ($) sign, after the class is made? Like this (probably incorrect): <?php class foo { echo "Hello World."; } ?> and then <?php echo $foo; ?> Or must it be another way? Reply with full (valid) script. Please.
