    Beispiele

    Beispiel #1 Basic ReflectionClass::getReflectionConstants() example

    <?php
    class Foo {
    public const     FOO = 1;
    protected const     BAR = 2;
    private const     BAZ = 3;
    }

    $foo = new Foo();

    $reflect = new ReflectionClass($foo);
    $consts = $reflect->getReflectionConstants();

    foreach (    $consts as $const) {
    print     $const->getName() . "\n";
    }

    var_dump($consts);

    ?>

    Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    FOO
BAR
BAZ
array(3) {
  [0]=>
  object(ReflectionClassConstant)#3 (2) {
    ["name"]=>
    string(3) "FOO"
    ["class"]=>
    string(3) "Foo"
  }
  [1]=>
  object(ReflectionClassConstant)#4 (2) {
    ["name"]=>
    string(3) "BAR"
    ["class"]=>
    string(3) "Foo"
  }
  [2]=>
  object(ReflectionClassConstant)#5 (2) {
    ["name"]=>
    string(3) "BAZ"
    ["class"]=>
    string(3) "Foo"
  }
}
