php如何处理一个对象，并且获取对象元素的值，下面有object？

Question

我想获取body的值，怎么做

object(HttpResponse)#11 (7) {
  ["content":"HttpResponse":private] => string(1047) "HTTP/1.1 200 OK

Answer 1

通过反射函数转化为数组可以处理这样的问题

$ref = new ReflectionClass($response);
        $props = $ref->getProperties();
        $arr = [];


        foreach ($props as $prop) {
            $prop->setAccessible(true);
            $arr[$prop->getName()] = $prop->getValue($response);
            $prop->setAccessible(false);
        }

可以得到这样的数组，问题解决了

array(7) {
  ["content"] => string(1048) "HTTP/1.1 200 OK

Answer 2

把对象转成数组看看

Answer 3

$object->body试下

Answer 4

get_object_vars 可以把对象转换为数组

Answer 5

在HttpResponse里加个

public function getBody()
{
    return $this->body;
}

Answer 6

谢邀.

不管对象里面有没有子对象，你可以采用下面的方法搞定

//将对象序列化，然后转换为数组
$arr=json_decode(json_encode($obj),true);

通过数组方式你很容易访问对象中的元素。
