PHP Functions - Maximum number of arguments

Question

In PHP, when defining a function what is the maximum number of arguments that you can create? This isn't something I am doing, just a question that popped up when discussing it with a colleague :)

Would this be purely down a memory limitation? effectively unlimited?

Answer 1

There is no limit. And you can always use func_get_args(), func_get_arg() and func_num_args() to avoid writing all the arguments in the function definition.
