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.
I believe it is - BUT it won't be easy, also I think you can only really do this
properly in php5 using a shedload of reflection functionality:
http://php.net/manual/en/language.oop5.reflection.php
although I wonder whether you shouldn't be re-evaluating what it is
your trying to do because I get the impression it's a whole load of work
for probably little payoff (consider that using alot of indirection in your
code will make it harder to understand/read and therefore harder to debug/maintain).
why not consider the possibility that all these 'by reference' args could be items
in a single 'by reference' array?
btw: have you met call_user_func_array() yet? (not that it
would solve the problem because it doesn't 'do' references) - also,
it's manual page offers a hack for the reference problem your working on.
