<?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）;?>
