Variable Argument List

[Daniel Kolbo <kolb0057@xxxxxxx>]

Hello,

I am trying to do something like the following:

<?php

function hello($var1 = 'default1', $var2 = 'default2') {
   echo "$var1:$var2";
}

$func= "hello";
$args = "'yo','bob'";
$func($args);

?>

I understand why this outputs:
'yo','bob':default2
However, I want it to output:
yo:bob

Is this possible? I tried using different combinations of {}, but I 
cannot seem to get it to happen.  I need some kind of "preprocessor" 
feature perhaps.

Thanks,
dK
