有什么像客观的c nil终止在PHP？

Question

In Objective-C, I can have a method like this:

+ (id)arrayWithObjects:(id)firstObj, ...;

I can pass as many object as I like, until I pass a nil in the last argument.

In php, can I have this ability also...? Thank you...

In PHP, you can do the same kind of thing -- except you don't have to pass null as a last parameter : just pass the parameters you want to your method.

Then, in this method, use functions such as func_get_args() to access the parameters it received.
