javascriptphp数组对象互转类

Posted 2020-11-17

一、javascript：

1. 代码：

   /*
   @desc：数组和对象互转类
   @param data 待转换的数据
   */
   function arrobj(data){
   this.data = data
   /*
    @desc：对象转数组
    */
   this.objtoarr = function(){
       var data = this.data
       var arr = new Array()
       for(var i in data){
           for(var j in data[i]){
               arr[j] = {}
           }
       }
       for(var i in data){
           for(var j=0;j<data[i].length;j++){
               arr[j][i] = data[i][j]
           }
       }
       return arr
   }
   /*
    @desc：数组转对象
    */
   this.arrtoobj = function(){
       var data = this.data
       var obj = {}
       for(var i in data){
           for(var j in data[i]){
               obj[j] = new Array()
           }
       }
       for(var i in data){
           for(var j in data[i]){
               obj[j][i] = data[i][j]
           }
       }
       return obj
   }
   }

2. 测试：

   var data = {
   id:[1,2,3],
   title:[‘title1‘,‘title2‘,‘title3‘],
   content:[‘content1‘,‘content2‘,‘content3‘]
   }
   var arrobj = new arrobj(data)
   var ret = arrobj.objtoarr()
   console.log(ret)

3. 输出：

   [ { id: 1, title: ‘title1‘, content: ‘content1‘ },
   { id: 2, title: ‘title2‘, content: ‘content2‘ },
   { id: 3, title: ‘title3‘, content: ‘content3‘ } ]

   二、php：

4. 代码：

   /**
   * @desc：对象与数组互转类
   * @author [Lee] <[<[email protected]>]>
   * @property
   *      data 传入的数据
   * @method
   *      objtoarr  对象转数组
   *      arrtoobj  数组转对象
   */
   class arrobj{
   private $data;
   /*
    @desc：构造方法，实例化待转换数据
    */
   public function __construct($data){
       $this->data = $data;
   }
   /*
    @desc：对象转数组
    */
   public function objtoarr(){
       $data = $this->data;
       $arr = array();
       foreach($data as $k=>$v){
           foreach($v as $k1=>$v1){
               $arr[$k1][$k] = $v1;
           }
       }
       return $arr;
   }
   /*
    @desc：数组转对象
    */
   public function arrtoobj(){
       $data = $this->data;
       $obj = array();
       foreach($data as $k=>$v){
           foreach($v as $k1=>$v1){
               $arr[$k1][$k] = $v1;
           }
       }
       return $arr;
   }
   }

5. 测试：

   $data = array(
       ‘id‘ => array(1,2),
       ‘title‘ => array(‘title1‘,‘title2‘),
       ‘content‘ => array(‘content1‘,‘content2‘)
   );
   $arrobj = new arrobj($data);
   $ret = $arrobj->arrtoobj();
   var_dump($ret);

6. 输出：

   array(2) {
   [0]=>
   array(3) {
   ["id"]=>
   int(1)
   ["title"]=>
   string(6) "title1"
   ["content"]=>
   string(8) "content1"
   }
   [1]=>
   array(3) {
   ["id"]=>
   int(2)
   ["title"]=>
   string(6) "title2"
   ["content"]=>
   string(8) "content2"
   }
   }
