$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); 
 
?>
