Or you can use an array:
function print_this( $ArrayValues ) {
do whatever using count($ArrayValues) to determine the bounds of the
array;
}

Alternatively, you can use the approach below. There are different benefits
from each approach. The following approach is particularly useful if you
want an unlimited number of parameters (like elipses in C).
function print_this ($value1, $value2)
{
if (3==func_num_args())
{
$maybe3=func_get_arg(2); // args are counted from 0 up
}
..
..
}

You can give $maybe3 a default value which will be used if it is not passed
in the function call.
You can only do this for the last parameter in the function.
function print_this ($value1, $value2, $maybe3=false)
{
do whatever
if ($maybe != false)
do whatever with $maybe
}

Is it possible to have a function that looks something like
function print_this( $value1, $value2, $maybe3) {
do whatever;
}
that would expect $value1, $value2 BUT would not care if $maybe3 came in
or not ? and not give an error message that there is a missing paramter
?
I know I can do a condition within the function, but just want to see if
there is a more technical approach as in from php to ignore that
optional per say variable.
I did look in my PHP book by wrox, but no luck.
Thanks !!!
