PHP function to calculate number of parameters passed to a function

Is there a PhP function that can count the number of parameters passed to another function? for example 

function tobeCounted ("numberOne","numberTwo","numberThree")
{
 //do something with the parameters
}

a function that will count the number of parameters passed to the function above then return three or the indexes of the parameters or parameters themseleves.

You need these:

func_num_args — Returns the number of arguments passed to the function

func_get_args — Returns an array comprising a function's argument list

From here:

func_num_args()

Use this to get the number of parameters passed

If you use func_num_args() then you get the amount of arguments, rather than func_get_args that gets you the array of arguments.
