Unity界面实现效果：
上两行：输入用户名、密码
注册：将输入的用户名、密码发送到数据库
显示：从数据库获取数据显示在下方
注意：
默认已设好PHP运行的相关Web环境：
1、Apache
2、MySQL
3、PHP
MySQL端
1、链接数据库，新建一个名为myscoresdb的数据库
2、创建如下图所示Table表，并添加如下三条数据
Unity端代码
1、C#
挂在到游戏物体上，注意给代码赋值对应的输入文本框和输出显示用的文本框
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class HiScoreApp : MonoBehaviour {
public InputField nameInputField;
public InputField scoreInputField;
public Text[] show;
// Use this for initialization
void Start () {
GameObject.Find("Register").GetComponent<Button>().onClick.AddListener(StartUpload);
GameObject.Find("Show").GetComponent<Button>().onClick.AddListener(StartShow);
}
void StartUpload()
{
StartCoroutine(UploadScore(nameInputField.text, scoreInputField.text));
nameInputField.text = "";
scoreInputField.text = "";
}
void StartShow()
{
StartCoroutine(DownloadScores(nameInputField.text, scoreInputField.text));
}
IEnumerator UploadScore(string name,string score)
{
WWWForm form = new WWWForm();
form.AddField("name", name);
form.AddField("score", score);
WWW www = new WWW("http://127.0.0.1/UploadScore.php", form);
yield return www;
if (www.error != null)
{
Debug.LogError(www.error);
}
else
Debug.Log(www.text); //PHP：echo'upload '.$UserID.":".$hiscore;
}
public class UserData
{
public int id;
public string name;
public int score;
}
IEnumerator DownloadScores(string name,string score)
{
WWW www = new WWW("http://127.0.0.1/downloadscores.php");
yield return www;
if (www.error != null)
Debug.Log(www.error);
else
{
Debug.Log(www.text);
//将PHP返回的数据解析为字典格式，并在show中展示
var dict = MiniJSON.Json.Deserialize(www.text) as Dictionary<string, object>;
int index = 0;
foreach(object v in dict.Values)
{
UserData user = new UserData();
MiniJSON.Json.ToObject(user, v); //将字典中的值反序列化为UserData
show[index].text = string.Format("ID:{0:D2} 名字：{1} 分数：{2}", user.id, user.name, user.score);
index++;
}
}
}
}
2、MiniJSON
放在Unity中即可，HiScoreApp脚本会用到它来解析数据
