You can add methods dynamically, but not in the same way that you can
add properties dynamically. You have two options:
1) Overloading the object
2) Using the classkit extension
(2) requires that you can add extensions to PHP on your server -- so,
for hosted solutions, it's out.
(1) can be accomplished in two ways, but in each, you need to setup your
class to allow overloading in the first place.
PHP4 has the overload() function; read about it at
http://php.net/overload
overload() sets up an environment where the magic methods __get(),
__set(), and __call() (this latter would be used to handle dynamic
methods) are utilized.
PHP5 has overloading built into the object model; see
http://php.net/oop5 for more information.
Either way, you need to add a __call() method to your class and tell it
how to handle dynamic methods.
