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); ?>
