Is it possible for classes not to have properties, but only methods ? e.g. below

[jd2007]

<?php

class example
{
// echoes hello
function a()
{
  echo "Hello";
}
// echoes goodby
function b()
{
  echo "Goodbye";
}
}

?>

that class is valid

Try it and see. Surely its quicker than taking up space on the board.
