It seems the interface names are actually listed in a defined order:
- "extends" takes precedence over "implements" (i.e. first will be interfaces from (implemented in) the parent class (if any), then interfaces implemented in the class itself)
- when multiple interfaces are implemented at one time/level, it can be:
+ from an "implements" : they're listed in the defined order
+ from an "extends" (a class extends another class which implements multiple interfaces; or an interface extends multiple interfaces) : they're listed in REVERSE order

<?php
interface Foo {}
interface
Bar {}
interface
Other {}
interface
Foobar extends Foo, Bar {}
interface
Barfoo extends Bar, Foo {}

class
Test1 implements Foo, Bar {}
class
Test2 implements Bar, Foo {}

class
Test3 extends Test1 {}
class
Test4 extends Test2 {}

class
Test5 extends Test1 implements Other {}

class
Test6 implements Foobar, Other {}
class
TestO implements Other {}
class
Test7 extends TestO implements Barfoo {}

$r=new ReflectionClass('Test1');
print_r($r->getInterfaceNames()); // Foo, Bar

$r=new ReflectionClass('Test2');
print_r($r->getInterfaceNames()); // Bar, Foo

$r=new ReflectionClass('Test3');
print_r($r->getInterfaceNames()); // Bar, Foo

$r=new ReflectionClass('Test4');
print_r($r->getInterfaceNames()); // Foo, Bar

$r=new ReflectionClass('Test5');
print_r($r->getInterfaceNames()); // Bar, Foo, Other

$r=new ReflectionClass('Test6');
print_r($r->getInterfaceNames()); // Foobar, Bar, Foo, Other

$r=new ReflectionClass('Test7');
print_r($r->getInterfaceNames()); // Other, Barfoo, Foo, Bar
?>
