PHP 反射类.如何获取属性的值?

2022-01-04 00:00:00 get reflection php

我在 PHP 中使用反射类，但我不知道如何获取反射实例中的属性值.有可能吗?

I'm using the reflection class in PHP, but I'm with no clues on how to get the values of the properties in the reflection instance. It is possible?

代码:

<?php

class teste {

    public $name;
    public $age;

}

$t = new teste();
$t->name = 'John';
$t->age = '23';

$api = new ReflectionClass($t);

foreach($api->getProperties() as $propertie)
{
    print $propertie->getName() . "
";
}

?>

如何获取 foreach 循环内的属性值?

How can I get the propertie values inside the foreach loop?

此致，

推荐答案

怎么样

  • ReflectionProperty::getValue - 获取属性值.

就你而言:

foreach ($api->getProperties() as $propertie)
{
    print $propertie->getName() . "
";
    print $propertie->getValue($t);
}

顺便说一句，因为你的对象只有公共成员，你也可以迭代它直接

On a sidenote, since your object has only public members, you could just as well iterate it directly

foreach ($t as $propertie => $value)
{
    print $propertie . "
";
    print $value;
}

或使用 get_object_vars 获取它们一个数组.

or fetch them with get_object_vars into an array.
