Question

我刚刚开始学习PHP @ school和第三项任务，我们必须创建一个TicTacToe游戏。我在youtube上关注了一个turorial视频，并制作了一款可玩的游戏。但它并不知道转向它的人。 IE：您可以继续按下提交按钮，计算机将继续填写O，而玩家无需填写X.

请有人解释我怎么能让剧本知道谁变成了？我想知道它背后的逻辑。因此，只有一个代码根本不会帮助我，请解释如何在切换转弯之前检查玩家是否填写了X.

请帮帮我。

Answer 1

你可以添加一个新变量$ _POST [＆＃39; player＆＃39;]你可以从0改为1或从1改为0，这样就可以通过玩家现在应该玩的值来知道。我不打算给你写代码，因为我给你一个提示应该怎么做，你必须自己学习：）

Answer 2

我会添加一个小的txt文件来保存最后一个文件的播放方式。

例如，您可以将许多不同的值保存到单个.txt文件中。

Applicative

您可以使用以下代码：

//保存下一位玩家的名字

ljoin . ljoin == ljoin . fmap ljoin

//加载播放器设置

<?php 

function savesettings($nextturn){

if(is_file("file.txt")){
$mysettings = unserialize(file_get_contents("file.txt"));
}else{
$mysettings = array();}
$mysettings["nextturn"]=$nextturn;
file_put_contents("file.txt",serialize($mysettings));
}

function loadsettings(){
if(is_file("file.txt")){
    $mysettings = unserialize(file_get_contents("file.txt"));
}else{
    $mysettings = array();
}
return $mysettings["nextturn"];

}

?>
