php利用嵌套数组拼接与解析json的方法


            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); 

 

?>
