Bug description: func_get_args returns copies of arguments, not referenced
values
Description:
------------
Calling func_get_args() returns copies of the arguments of the function.
It would be more useful to return referenced values if those are defined in
the function parameters.
This is useful when using func_get_args() for function parameter
overloading and calling other functions from a function using
call_user_func_array().
A bit off topic: I see var_dump is aware if the variable is a referenced
one. Would it be possible to implement a 'is_reference()' function now?
Reproduce code:
---------------
$a = 1;
$b = 2;
$c = "3";
function f($a, &$b, &$c)
{
var_dump(func_get_args());
}
var_dump(array($a, &$b, &$c));
f($a, $b, $c);
Expected result:
----------------
array(3) {
[0]=>
int(1)
[1]=>
∫(2)
[2]=>
&string(1) "3"
}
array(3) {
[0]=>
int(1)
[1]=>
∫(2)
[2]=>
&string(1) "3"
}
Actual result:
--------------
array(3) {
[0]=>
int(1)
[1]=>
∫(2)
[2]=>
&string(1) "3"
}
array(3) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
string(1) "3"
}
