Instead of aliasing, I would deprecate the function, so the old
function would be:
function categorise($arg1, $arg2) {
trigger_error('Deprecated categorise used', E_USER_NOTICE);
return categorize($arg1, $arg2);
}
As far eliminating the parameter changes, I can only think that
you'd need to use func_get_args() and call_user_func_array():
function categorise() {
call_user_func_array('categorize', func_get_args());
}
The latter solution is quite a bit of overhead just to get an alias,
perhaps trigger_error with that method as you migrate old code.
