Quick and handy PHP snippet

Here is something that you may find helpful. If you want to toggle between two states of something, you can use this:

Set a variable to 1, such as $a

and then

$a=3-$a;

Each time it executes, it will toggle between $a=1 and $a=2. This is helpful if you have something like different color lines for each line of data.

Just a quick thought...
