ReflectionClass::getProperty — 获取类的一个属性的 ReflectionProperty
获取类的一个属性的 ReflectionProperty。
name属性名。
示例 #1 ReflectionClass::getProperty() 的基本用法
<?php
$class = new ReflectionClass('ReflectionClass');
$property = $class->getProperty('name');
var_dump($property);
?>以上示例会输出：
object(ReflectionProperty)#2 (2) {
["name"]=>
string(4) "name"
["class"]=>
string(15) "ReflectionClass"
}
If the class doesn't have a property with the given name, a ReflectionException will be raised.Accessing private properties is possible, but care must be taken if that private property was defined lower into the inheritance chain. For example, if class A extends class B, and class B defines a private property called 'foo', getProperty will throw a ReflectionException.
Instead, you can loop over getParentClass until it returns false to look for the private property, at which point you can access and/or modify its value as needed.
