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

?>
