php利用嵌套数组拼接与解析json的方法

// 自 PHP 5.4 起

$array= [

  "status"=>"0",

  "message"=>"ok",

  "arr"=> []

];

classPerson { 

  public$name; 

  public$age; 

  //定义一个构造方法初始化赋值 

  publicfunction__construct($name,$age) { 

    $this->name=$name; 

    $this->age=$age; 

  } 

} 

for($i=0;$i<10;$i++)

{

  $p=newPerson("ren",$i); 

  $array["arr"][]=$p;

}

//var_dump($array);

echojson_encode($array);

?>

    else$arr[$k]=$v; 

  }
