我的程序是一个简单的tic tac toe游戏，我的获奖者没有正确显示只有4个正确的是两个对角线和行的胜利和列胜利.html / javascript不是问题它只是PHP
<?php
//Players
$X = "Dalton";
$O = "Joe";
$winner = false;
//game board positoins
$r1c1 = !empty($_POST['r1c1'] ) ? $_POST['r1c1'] : '';
$r1c2 = !empty($_POST['r1c2'] ) ? $_POST['r1c2'] : '';
$r1c3 = !empty($_POST['r1c3'] ) ? $_POST['r1c3'] : '';

The Javascript code below requires access to the internet to run. If you are
running this page on a computer with no Internet access, it will cause errors.
You may delete these lines or modify them if you wish.
The 1st block in the code below is helping you by not allowing any character
except an uppercase 'X' or uppercase 'O'. This is unnessisary, but makes it easier
for you to process on the PHP side.
The 2nd block of code is helping you by making any field that already has has
'X' or 'O' readonly when the page loads. Extra points will be giving to any student
how can replicate this part of the Javascript using only PHP. Simply delete the lines
below if you wish to attempt.

Notice that the default values for each box below is set to '', and empty string.
You will have to set them using data from the $_POST, if you don't the game will
reset after every move. Something like this for every box maybe ...
if( !empty($_POST['r1c0']) ) {
$r1c0 = $_POST['r1c0'];
} else {
$r1c0 = '';
}

答案 0 :(得分：0)
在代码顶部添加这样的内容应该可以使它工作。您的一些单元格正在传递小写值。您可能应该进行一些其他错误检查，因为Javascript可以被操纵。
foreach ($_POST as $key => $val) {
$_POST[$key] = strtoupper($val);
}
