To make the second argument optional, you should declare the
function as such:
function myFunc( $firstArgument, $secondArgument = "" ) {
}
The above is defaulting the second argument to nothing/null/no value.
You could default to any value you wish. If the argument is not passed,
the default value will be used, whatever it is set to.
