本篇文章主要介紹了php利用嵌套數(shù)組拼接與解析json的方法，小編覺得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過來看看吧

利用嵌套數(shù)組拼接混合json -包含對(duì)象數(shù)組

<?php 
 
// 自 PHP 5.4 起 
$array = [ 
  "status" => "0", 
  "message" => "ok", 
  "arr"=> [] 
]; 
 
class Person {  
  public $name;  
  public $age;  
  
  //定義一個(gè)構(gòu)造方法初始化賦值  
  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利用嵌套數(shù)組解析混合json 包含對(duì)象數(shù)組

<?php  
function json_to_array($web) {  
  $arr=array();  
  foreach($web as $k=>$v) {  
    if(is_object($v)) $arr[$k]=json_to_array($v); //判斷類型是不是object  
    else $arr[$k]=$v;  
  }  
  return $arr;  
}  
$s='{"webname":"homehf","url":"www.homehf.com","qq":"744348666"}';  
//將字符轉(zhuǎn)成JSON  
$web=json_decode($s);  
$arr=array();  
foreach($web as $k=>$v)  
  $arr[$k]=$v;  
echo "<pre>";  
print_r($arr);  
echo "</pre>";
