利用嵌套数组拼接混合json -包含对象数组

<?php// 自 PHP 5.4 起$array = [    "status" => "0",    "message" => "ok","arr"=> []];class Person {      public $name;      public $age;        //定义一个构造方法初始化赋值      public function __construct($name,$age) {          $this->name=$name;          $this->age=$age;      }  }     for($i=0;$i<10;$i++){$p=new Person("ren",$i); $array["arr"][]=$p;}//var_dump($array);echo json_encode($array);?>
