Just make them all references, if it was expecting a copy it will just
get a reference to a copy, if it was expecting a reference it will get
one. I do a similar trick in a class loader I use that copes with
variable length argument lists and passing by reference.
A bit like this
$num_args = func_num_args();
$arg_list = func_get_args();
$vars = 'function_to_call(';
for ($i = 0; $i < $num_args; $i++) {
$vars .= ($i > 0)? ',':'';
$varname = 'variable'.$i;
$$varname =& $arg_list[$i];
$vars .= "\$$varname";
}
$vars .= ');';
//that leaves you with a string you can use eval on
eval($vars);
