I am not sure if this should be considered a bug. If it should be, I
would be happy to report it. I did a search for debug_backtrace and
static and found no hits in the bug database.
If you call a static method from inside of another classes method,
debug_backtrace reports the calls as being a method of the hosting
object's class, not the static call. IMO, it should still be reported
as a static function call, even if it happens to be invoked from
within a class. Here is a simple test case:
class S {
function bt() {
$bt = debug_backtrace();
echo $bt[0]['class'], $bt[0]['type'], $bt[0]['function'], "\n";
}
}
class C extends S {}
class O {
function t() {
S::bt();
}
}
//okay S::bt
S::bt();
//also okay C->bt
$o = new C;
$o->bt();
// problem? reports O->bt, but I think it should have been S::bt
$o2 = new O;
$o2->t();
Is this perhaps caused by confusion related to the scope resolution
operator between the static call, and trying to resolve parent::
inheritance?
