You may pass any number of extra parameters to a function, regardless of the prototyping. In
addition, the arguments passed to a function will be available via the variable names defined in the
function prototype, as well as via the func_get_arg() and func_get_args() functions.
For example:
function printme ($arg) {
for ($ndx = 0; $ndx < $num_args; ++$ndx)
$output .= func_get_arg ($ndx);
print $output;
}
printme ("one ", "two"); # This prints "one two".
This behavior is useful for setting default values for function arguments and for ensuring that a
certain number of arguments get passed to a function.
