【php简记】php遍历json数组出错：Object of class stdClass could not be converted to string

【错误遍历方法】

需要解析的json数据：

[{"data":"/storage/emulated/0/yhpco/camera/201905151565440637188xakfl.jpg","id":"0","title":"","type":""}]

错误方法：

for($i=0;$i<=sizeof($arrays);$i++){
                           echo $arrays[$i];
                        }

或：

foreach ($arrays as $val) {
                           echo $val;
                           echo $val['type'];
     }

【纠正】应使用以下方法

foreach ($arrays as $vals) {
                           echo $vals->type;
      }
