Bug description: Destructor order for global objects
Description:
------------
If several objects are created in the global scope, their destructors are
called in the same order the objects were created, not in the reverse
order. PHP documentation does not promise anything certain about the order
in which destructors are called, but the common practice for many
object-oriented languages is to call the destructors in the reverse order.
This usually (though not always) is better in cases when the objects being
destroyed depend on each other. I think that the order of destructor calls
for global objects should be reverse compared to the order of their
creation. Actually, the same is already true for function local variables.
Reproduce code:
---------------
class C1 {
function __construct() {
print "Constructing " . get_class($this) . "\n";
}
function __destruct() {
print "Destroying " . get_class($this) . "\n";
}
}
class C2 {
function __construct() {
print "Constructing " . get_class($this) . "\n";
}
function __destruct() {
print "Destroying " . get_class($this) . "\n";
}
}
$c1 = new C1();
$c2 = new C2();
Expected result:
----------------
Constructing C1
Constructing C2
Destructing C2
Destructing C1
Actual result:
--------------
Constructing C1
Constructing C2
Destructing C1
Destructing C2
