    For interfaces and traits :

    <?php
    interface TestInterface { }
    trait         TestTrait { }

    $interfaceClass = new ReflectionClass('TestInterface');
    $traitClass     = new ReflectionClass('TestTrait');

    var_dump($interfaceClass->isAbstract());
    var_dump($traitClass->isAbstract());
    ?>

    Using PHP versions 5.4- to 5.6, the above example will output:

    bool(false)
    bool(true)

    Using PHP versions 7.0+, the above example will output:

    bool(false)
    bool(false)

    For traits:
    - ReflectionClass::isAbstract returns true if the trait contains at least one un-implemented abstract method, including those declared into used traits.
    - ReflectionClass::isAbstract returns false if all methods are implemented.

    <?php
    trait TI { public function has() {} }
    var_dump((new ReflectionClass(TI::class))->isAbstract());

    trait     TT { abstract public function has(); }
    trait     T { use TT; }
    var_dump((new ReflectionClass(T::class))->isAbstract());
    ?>
    Will output:
    bool(false)
    bool(true)

    For interfaces:
    - ReflectionClass::isAbstract returns true if the interface contains at least one method, including into its extended interfaces.
    - ReflectionClass::isAbstract returns false if the interface contains no method.

    <?php
    interface AI {}
    var_dump((new ReflectionClass(AI::class))->isAbstract());

    interface     II { public function has(); }
    interface     I extends II {}
    var_dump((new ReflectionClass(I::class))->isAbstract());
    ?>
    Will output:
    bool(false)
    bool(true)

    For classes:
    - Reflection::isAbstract returns true if the class is marked as abstract, no matter if it contains abstract methods or not.
