ReflectionFunction::invokeArgs — Invokes function args
Invokes the function and pass its arguments as array.
argsThe parameters to be passed to the function, as an array, much like call_user_func_array() works.
If the keys of args are all numeric, the keys are
ignored and each element is passed to the function as a positional
argument, in order.
If any keys of args are strings, those elements are
passed to the function as named arguments, with the name given by the
key.
An Error is thrown if a numeric key in
args appears after a string key, or if a string key
does not match the name of any parameter of the function.
Returns the result of the invoked function

args keys will now be interpreted as parameter names, instead of being silently ignored.
