variable number of args

[bill]

I have a function that always has at least one argument and may
have a 2nd.

Can I pass the first by reference and then check to see if there
is a 2nd, e.g:

procedure foo($bar){

echo $bar;

$numargs = func_num_args();
if ($numargs) {
$bar2 = func_get_arg(1);
echo $bar2;
...
}

or must I get both args using func_get_arg() or func_get_args() ?

Or even
procedure foo($bar, $bar2 = NULL){

ITYM: function foo($bar, $bar2 = NULL){

I just copied the line from the OP. I didn't even read that it said
procedure, I read it as function!

have you considered passing an array?

function doit($a=array()){
echo 'I have '.count($a).' items!';
foreach ($a as $key => $value) {
echo "Key: $key; Value: $value<br />\n";
}
}

Should always be the last option. If you just have a small number of
arguments, maybe even with some being optional, explicitly define them
like that.

Passing them all as an array not only complicates the code, but will
also interfere with many features in modern IDEs like code completion,
auto documentation and debugging.
