Passing an indefinite number of parameters by reference

Hi, Currently I have a function which accepts a limited number of parameters: call_function($function_name, &$var_1, &$var_2); I wish to modify the function to accept an indefinite number of parameters, which may or may not be references. The function call_function() then calls the function specified in $function_name, with the variables passed as parameters to that function. Is this possible? Thanks for any help which can be offered.
