示例 #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);
?>以上示例的输出类似于：
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" } }
