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);

?>

Il precedente esempio visualizzerĂ  qualcosa simile a:

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"
  }
}
