Example #1 Basic ReflectionClass::getReflectionConstants() example
<?phpclass 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);?>
The above example will output something similar to:
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" } }
