php – 如何获取数组中对象元素的值？

我给你介绍个对象吧！ 2020-10-03 09:10:32

如下所示,var_dump出来的结果，我想取出error的内容

array(2) {

  [0] => NULL

  [1] => object(Qiniu\Http\Error)#37 (2) {

    ["url":"Qiniu\Http\Error":private] => string(71) "http://rs.qiniu.com/delete/dGVzdHlqczphcmNoaXRlY3R1cmUtMTQ3NzA5OC5qcGc="

    ["response":"Qiniu\Http\Error":private] => object(Qiniu\Http\Response)#38 (6) {

      ["statusCode"] => int(612)

      ["headers"] => array(8) {

        ["Server"] => string(9) "openresty"

        ["Date"] => string(19) "Sat, 03 Oct 2020 01"

        ["Content-Type"] => string(16) "application/json"

        ["Content-Length"] => string(2) "37"

        ["Connection"] => string(10) "keep-alive"

        ["Cache-Control"] => string(8) "no-store"

        ["X-Reqid"] => string(16) "0cQAAABpWCooVjoW"

        ["X-Log"] => string(1) "-"

      }

      ["body"] => string(37) "{"error":"no such file or directory"}"

      ["error"] => string(25) "no such file or directory"

      ["jsonData":"Qiniu\Http\Response":private] => array(1) {

        ["error"] => string(25) "no such file or directory"

      }

      ["duration"] => float(0.074)

    }

  }

}

//使用json_decode()函数
$json = json_decode( $str, 1 );//$str代表你上面那段的字符串内容
$data=$json['1']['response'];
$error=$data['error'];
echo $error;

因为 error 在 Qiniu\Http\Error 类的私有属性response 上，你的看该类是否有 __get()这样的方法是否能获取到 response 这个属性，然后你就可以 $arr[1]->response ->error; 如果是有类似 getResponse 的方法来获取response 属性就 $arr[1]->getResponse ()->error;
