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); 

    ?> 

php利用嵌套数组 解析混合json 包含对象数组

    <?php  
    function json_to_array($web) {  
      $arr=array();  
      foreach($web as $k=>$v) {  
        if(is_object($v)) $arr[$k]=json_to_array($v); //判断类型是不是object  
        else $arr[$k]=$v;  
      }  
      return $arr;  
    }  
    $s='{"webname":"homehf","url":"www.homehf.com","qq":"744348666"}';  
    //将字符转成JSON  
    $web=json_decode($s);  
    $arr=array();  
    foreach($web as $k=>$v)  
      $arr[$k]=$v;
