Does PHP have ability to do OPTIONAL on function arguements?

Just curious...haven't seen anything that would lead me to believe that it does.

To my knowledge, you cannot truly have it unset. However, you can set it as a blank variable (it is still set, and will register with is_set()).
Here is an example of how to do so:
function test($arg1 = "") {
echo($arg1);
}

From reading the page link in the previous post, the specific answer to the specific question of OPTIONAL arguements is flat out NO.

Currently, you can have DEFAULT arguements but no OPTIONAL ones.
