数组操作object转json

Posted 2023-05-16

参考技术A //数组操作object转json

    public function shuju()

    $sites = array(

    "runoob"=>array ( "菜鸟教程","http://www.runoob.com"),

    "google"=>array( "Google 搜索","http://www.google.com"),

    "taobao"=>array("淘宝","http://www.taobao.com")

    );

    echo "sites整个数组显示：<br>";

    var_dump($sites);echo "<br><br>";

    echo "sites单个值显示：<br>";

    echo $sites['runoob'][0]."<br><br>";

    $content = DB::table('ms_user')

            ->where('phone','=','13683288938')

            ->get();

    echo "content整个数组显示：<br>";

    var_dump($content);echo "<br><br>";

    echo "content转成json整个数组显示：<br>";

    $object = json_decode( json_encode( $content),true);

    var_dump($object);echo "<br><br>";

    echo "object单个值显示：<br>";

    echo $object[0]['id'] . "<br><br>";

   

Object 转 json 工具类

/**
* 把数据对象转换成json字符串 DTO对象形如：{"id" : idValue, "name" : nameValue, ...}
* 数组对象形如：[{}, {}, {}, ...] map对象形如：{key1 : {"id" : idValue, "name" :
* nameValue, ...}, key2 : {}, ...}
*
* @param object
* @return

public static String getJSONString(Object object) {

try{
jsonConfig.registerJsonValueProcessor(Date.class,new JsonDateValueProcessor());
//整形转换为字符串

if (object != null) {
if (object instanceof Collection || object instanceof Object[]) {
