Description:
------------
I feel the SWITCH documentation might best include code for dealing with inequalities in a CASE, using switch(TRUE).

People are posting User Notes with implementations relying on type conversion of a random number to boolean TRUE, as the switch argument.

This will cause a confusing logic error any time the argument is zero. Here's an example to help people get the right idea:

Reproduce code:
---------------
<?php

$rand=rand(-3,+3);

// Good use of switch() with inequalities: note TRUE is the argument, and all rand() outcomes are covered without overlap
switch(TRUE) {
	case $rand < 0:
		print "$rand is less than zero";
	break;
	
	case $rand == 0:
		print "$rand is equal to zero";
	break;
	
	case $rand > 0:
		print "$rand is greater than zero";
	break;
}

?>
