Andrew Podner:
Overloading Create PHP Class Methods on the Fly
March 06, 2013 @ 11:51:57

Andrew Podner has a new post today looking at dynamic class method creation in PHP - aka "overloading" with the __call magic method.

What is overloading and what would I need it for? [...] In most languages, overloading just means you can have multiple methods with the same name, but they just had a different number/type of arguments. In PHP, it is a little different. Overloading in PHP means that you can actually create dynamic function names and the behavior will be dependent upon the function name that is used.

He gives an example through a sample application, first stating the requirements the business has for it then showing how to use the "__call" method to handle "getBy" requests made to a database class. It searches the database based on the field (ex. "getByusername" searches on "username") and he includes two examples of it in use. He also briefly touches on the use of the "__callStatic" magic method for handling static method calls similarly.
