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);

?>

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"
  }
}
