You don't need function overloading in PHP. Why? First you need to look at
why other languages need it:
(a) To accept arguments of different types.
(b) To make some arguments optional.
With PHP you can accept an argument of any type and then cast it to the one
you want, so item (a) is irrelevant.
With PHP you can define a default value for an argument if it is not
supplied, so item (b) is irrelevant.
