利用php嵌套數組拼接並解析json

本篇文章主要介紹了php利用嵌套數組拼接與解析json的方法，內容挺不錯的，現在分享給大家，也給大家做個參考。

利用嵌套數組 拼接混合json -包含對象數組

<?php  // 自 PHP 5.4 起 $array = [   "status" => "0",   "message" => "ok",   "arr"=> [] ];  class Person {    public $name;    public $age;      //定義一個構造方法初始化賦值    public function __construct($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利用嵌套數組 解析混合json 包含對象數組

<?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"}';  //將字元轉成JSON  $web=json_decode($s);  $arr=array();  foreach($web as $k=>$v)    $arr[$k]=$v;  echo "<pre>";  print_r($arr);  echo "</pre>";    $s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';  $web=json_decode($s);  $arr=json_to_array($web);  echo "<pre>";  print_r($arr);  echo "</pre>";    /************************************************************************ ************************************************************************/  $s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';  $web=json_decode($s);  echo '網站名稱：'.$web->webname.'<br />網址：'.$web->url.'<br />連絡方式：QQ-'.$web->contact->qq.' MAIL:'.$web->contact->mail;  echo '<br /><br />';  /************************************************************************ ************************************************************************/  $s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf@163.com","xx":"xxxxxxx"}}';  $web=json_decode($s);  echo json_encode($web);    $mys='{"status":"0","message":"ok","arr":[{"name":"ren","age":0},{"name":"ren","age":1},{"name":"ren","age":2}, {"name":"ren","age":3},{"name":"ren","age":4},{"name":"ren","age":5},{"name":"ren","age":6},{"name":"ren","age":7}, {"name":"ren","age":8},{"name":"ren","age":9}]}';  $myweb=json_decode($mys);   echo $myweb->status;  for($i=0;$i<10;$i++) {  echo $myweb->arr[$i]->age;  echo '<br /><br />';  }  ?>
