PHP Function Argument Lists

A lot of PHP developer's don't know about PHP's support for variable-length argument lists.

This is a quite an easy feature to use and can be useful when you're not sure how many arguments a function should accept.

To declare a function with a variable-length argument list, declare it with an empty argument list.

Calling the function with multiple arguments is easy...

Processing the arguments inside the function is also an easy task using the func_get_arg(), func_get_args() and func_num_args() functions.
