Wrong closure scope class reported for static methods #8932
Description
Description
The following code:
class A
{
public static function b()
{
echo static::class;
}
}
class B extends A
{
}
$c = ['B', 'b'];
$d = \Closure::fromCallable($c);
$r = new \ReflectionFunction($d);
var_dump($r->getClosureScopeClass());
$d();Resulted in this output:
object(ReflectionClass)#41 (1) {
["name"]=>
string(1) "A"
}
B
But I expected this output instead:
object(ReflectionClass)#41 (1) {
["name"]=>
string(1) "B"
}
B
Right now, there is no way to turn back a named closure into a regular callable because reflection doesn't give back the "called class" ("B" here.)

Yeah, that looks like a bug. The problem is that we're loosing the
called_scopeduring construction of theReflectionFunction, and it seems there is currently no way to retrieve it later.Fix phpGH-8932: Wrong closure scope class reported for static methods
