    Exemples

    Exemple #1 Exemple avec ReflectionClass::getInterfaceNames()

    <?php
    interface Foo { }

    interface     Bar { }

    class     Baz implements Foo, Bar { }

    $rc1 = new ReflectionClass("Baz");

    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
    ?>

    For the record, it will return the full name (not the short name) for each Interface

    Example with namespace would've helped.
