Phil Sturgeon has another post to his site about a recently proposed RFC for PHP. This time it's about implementing a variadic function syntax in the language. This kind of handling would allow for a variable number of parameters on a function/method and not having to use func_get_args to pull in the list.

An awesome RFC popped up the other day: Syntax for variadic functions, developed by Nikita Popov. I read through it and I loved it, but I did have to Google to see what the hell a variadic function was. This is what happens when you teach yourself how to code. You know how to do things, but don't know any of the words. Variadic functions are already possible in PHP and have been throughout 4.x and 5.x in the form of func_get_args(), which is pretty gross.

He includes an example of how it would work and some of the pros and cons of implementing it in the language including:

• Type hinting (pro)
• Argument unpacking (con)
• Easier documentation in docblocks (pro)
• Keeping up with the "Joneses" (con)
