    Örnek 1 - ReflectionClass::hasMethod() örneği

    public function     publicFoo() {
    return     true;
    }

    protected function     protectedFoo() {
    return     true;
    }

    private function     privateFoo() {
    return     true;
    }

    static function     staticFoo() {
    return     true;
    }
    }

    $rc = new ReflectionClass("C");

    var_dump($rc->hasMethod('publicFoo'));

    var_dump($rc->hasMethod('protectedFoo'));

    var_dump($rc->hasMethod('privateFoo'));

    var_dump($rc->hasMethod('staticFoo'));

    // bar diye bir yöntem olmaması lazım
    var_dump($rc->hasMethod('bar'));

    // Yöntem isimleri harf büyüklüğüne duyarsızdır
    var_dump($rc->hasMethod('PUBLICfOO'));
    ?>

    Parent methods (regardless of visibility) are also available to a ReflectionObject.  E.g.,

<?php
class ParentObject {
  public function parentPublic(  ) {
  }

  private function parentPrivate(  ) {
  }
}

class ChildObject extends ParentObject {
}

$Instance = new ChildObject();
$Reflector = new ReflectionObject($Instance);

var_dump($Reflector->hasMethod('parentPublic'));  // true
var_dump($Reflector->hasMethod('parentPrivate')); // true
?>

    Trait methods can be seen by both actual and alias names<?phptrait Sauce{    public function getSpicy()    {        return 'Cayenne';    }}class Sandwich{    use Sauce {        Sauce::getSpicy as getSweet;    }}$class = new \ReflectionClass('Sandwich');var_dump($class->hasMethod('getSweet'));var_dump($class->hasMethod('getSpicy'));?>bool(true)bool(true)

    Annotated methods that are implemented using PHP magic methods are not recognized  by "hasMethod".<?php/** * @method void annotatedMethod() */class SomeClass{    public function __call($name, $arguments)    {        echo "this is magic method: $name.\n";    }    public function codedMethod()    {        echo "this is coded method.\n";    }}$obj = new \SomeClass();$obj->codedMethod();$obj->annotatedMethod();$ref = new ReflectionClass(\SomeClass::class);echo "SomeClass has 'codedMethod': " . json_encode($ref->hasMethod('codedMethod')) . ".\n";echo "SomeClass has 'annotatedMethod': " . json_encode($ref->hasMethod('annotatedMethod')) . ".\n";?>Output:this is coded method.this is magic method: annotatedMethod.SomeClass has 'codedMethod': true.SomeClass has 'annotatedMethod': false.

    note that even if private method will also be 'has'.

    It might be interesting to know that this is the only method to determine if a trait has a specific method:  trait a{    function __wakeup(){}  }  class b{}  class c{    use a;  }  var_dump((new ReflectionClass('a'))->hasMethod('__wakeup')); // true  var_dump((new ReflectionClass('b'))->hasMethod('__wakeup')); // false  var_dump((new ReflectionClass('c'))->hasMethod('__wakeup')); // true

    A way to check if you can call an method over a class:<?phpfunction is_public_method(        /* string */$className,        /* string */$method){    $classInstance = new ReflectionClass($className);    if ($classInstance->hasMethod($method)) {        return false;    }    $methodInstance = $instance->getMethod($method);    return $methodInstance->isPublic();}?>
