范例

BasicReflectionClass::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);
?>

以上例程的输出类似于：

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"
  }
}
