我正在尝试使用平面文件创建一个评分系统（我知道，我也更喜欢使用 mysql）。我已经设法创建了足够的变量，以便将变量从游戏中提取（用户名和分数）并放入所述文本文件中。我还可以在格式化表中输出此文本文件。但是，我无法按任何顺序对分数进行排序 - 理想情况下，我想要降序。搜索网络后，我能找到的最好的是在附加的代码中，但是目前这似乎实际上没有任何作用。我知道这可能是一个愚蠢的错误，但我可以用一双新鲜的眼睛来审视它。非常感谢，哈利
<?php
echo '<table width="5%" border="5"><tr><th>Your Score</th><th>Your Name</th></tr>';
echo '<tr><td>'.$_POST["m_score"].'</td><td>'.$_POST["name"].'</td></tr>';
echo '</table>';
echo "<br />";
$data=$_POST["m_score"].",".$_POST["name"].",";
$filename = "./highscores.txt";
$handle = fopen($filename, "a");
if (!$handle)
{
print "There were problems opening the file";
exit();
}
fwrite($handle, $data);
fclose($handle);
$handle = fopen($filename, "r");
$datain = fread($handle, filesize($filename));
$value = explode(",",$datain);
$row = floor(count($value)/2);
$count = 0;
$filename = file("./highscores.txt");
sort($filename);
file_put_contents("./highscores.txt", implode($filename));
echo '<table width="5%" border="1"><tr><th>Top Scores</th><th>Top Users</th></tr>';
for ($i=0;$i<$row;$i++)
{
echo '<tr>';
for($x=0;$x<2;$x++){
echo "<td>$value[$count]</td>";
$count++;
}
echo "</tr>";
}
echo '</table>';
fclose($handle);
?>

了一个例子，你可以看看学习，如果你真的不喜欢让一个成熟的mySQL服务器处理你的数据，那么这就是你可以用内置的sqlite2函数做到这一点的方法，超级简单和有用的小数据，因为任何类型的SQL总是更快的查询速度和更容易插入，然后是平面文件。希望它有帮助：
<?php

<p>Name: <input type="text" name="name" size="20"></p>
<p>Score: <input type="text" name="m_score" size="20"><input type="submit" value="Submit"></p>
</form>';
//Validate score as a number and the name is set
if(isset($_POST['m_score']) && is_numeric($_POST['m_score']) && !empty($_POST['name'])){
$name = $_POST['name'];
$m_score = $_POST['m_score'];
//Put result into database
database("INSERT INTO scores (id,name , m_score) VALUES (NULL,'".sqlite_escape($name)."',".(int)$m_score.")",'put',$db);
//Show users score
echo '<table width="5%" border="5"><tr><th>Your Score</th><th>Your Name</th></tr>';
