unity+MAMP(1)：为游戏搭建数据库_如何给自己的游戏添加数据库

链接：油管视频

下载MAMP之后，在web server的文件夹路径中加入配置文件：

login.php

<?php
$con = mysqli_connect('localhost','root','root','unitycpr');

	//check that connection happened
	if(mysqli_connect_errno())
	{
		echo "1: Connection failed";
		exit();
	}

	$username = $_POST["name"];
	$password = $_POST["password"];

	//check if name exits
	$namecheckquery = "SELECT username, salt,hash,score FROM players WHERE username='" . $username . "';";

	$namecheck = mysqli_query($con,$namecheckquery) or die("2: Name check query failed");

	if(mysqli_num_rows($namecheck) != 1)
	{
		echo "5: Either no user with name, or more than one";
		exit();
	}

	$existinginfo = mysqli_fetch_assoc($namecheck);
	$salt = $existinginfo["salt"];
	$hash = $existinginfo["hash"];

	$loginhash = crypt($password, $salt);
	if($hash != $loginhash)
	{
		echo "6: Incorrect password";
		exit();
	}

	echo "0\t" . $existinginfo["score"];
