Do functions have to be defined before they are used?

In PHP3, yes; in PHP4, no.

Classes are an exception to this rule. It does'nt matter in what order
you define your methods and even the constructor. The parser treads
classes completely different. The whole class gets loaded and the
function table is rebuild before the constructor is called.
