方法可以在类之外定义吗？

Question

I'm just getting into using classes in php and am coming from a C++ background. Literally every example I've seen shows methods being defined inside of the class definition, and I'm wondering if I can define my class methods outside of the class definition in order to improve readability?

Answer 1

Sort of. PHP 5.4 itroduced traits which is about as close as you're gonna get.
