示例 #1 ReflectionProperty::getValue() example
<?php
class Foo {
public static $staticProperty = 'foobar';
public $property = 'barfoo';
protected $privateProperty = 'foofoo';
}
$reflectionClass = new ReflectionClass('Foo');
var_dump($reflectionClass->getProperty('staticProperty')->getValue());
var_dump($reflectionClass->getProperty('property')->getValue(new Foo));
$reflectionProperty = $reflectionClass->getProperty('privateProperty');
$reflectionProperty->setAccessible(true); // only required prior to PHP 8.1.0
var_dump($reflectionProperty->getValue(new Foo));
?>以上示例会输出：
string(6) "foobar" string(6) "barfoo" string(6) "foofoo"
