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);  ?>
