Examples

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=consts = consts=reflect->getReflectionConstants();

foreach ( constsasconsts as constsasconst) {
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" } }
