| 版本 | 说明 |
|---|---|
| 8.3.0 | Calling this method with a single argument is deprecated, ReflectionClass::setStaticPropertyValue() should be used instead to modify static properties. |
| 8.1.0 | Private and protected properties can be accessed by ReflectionProperty::setValue() right away. Previously, they needed to be made accessible by calling ReflectionProperty::setAccessible(); otherwise a ReflectionException was thrown. |
示例 #1 ReflectionProperty::setValue() example
<?php
class Foo {
public static $staticProperty;
public $property;
protected $privateProperty;
}
$reflectionClass = new ReflectionClass('Foo');
// As of PHP 8.3, setValue should no longer be used to set static property value, use setStaticPropertyValue() instead
$reflectionClass->setStaticPropertyValue('staticProperty', 'foo');
var_dump(Foo::$staticProperty);
$foo = new Foo;
$reflectionClass->getProperty('property')->setValue($foo, 'bar');
var_dump($foo->property);
$reflectionProperty = $reflectionClass->getProperty('privateProperty');
$reflectionProperty->setAccessible(true); // only required prior to PHP 8.1.0
$reflectionProperty->setValue($foo, 'foobar');
var_dump($reflectionProperty->getValue($foo));
?>以上示例会输出：
string(3) "foo" string(3) "bar" string(6) "foobar"
