    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.<?phptrait 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.<?phpinterface 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.
