Example #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);

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" } }
