Question

我有一个包含欧洲足球队成绩的csv文件。我希望用户进入一个团队，然后希望系统显示该团队的结果，包括损失。

我设法用php读取csv文件。

如何从程序用户中读取团队名称？

如何查询CSV文件以便检索该团队的结果？

从http://www.football-data.co.uk/mmz4281/1718/I1.csv中读取数据（2017/2018赛季意大利足球比赛结果，结果；比赛统计数据；比赛总进球）

到目前为止，这是我的代码，共有2个文件：

<?php

include('init.inc.php');
header('Content-type: text/plain');
print_r(read_csv('I1.csv'));
$data = read_csv('I1.csv');

<?php

function read_csv($filename){
    $rows = array();

    foreach (file($filename, FILE_IGNORE_NEW_LINES)as $line){
      $rows[] = str_getcsv($line);
    }

    return $rows;
}

function write_csv($filename, $rows){
    $file = fopen($filename, 'w');

    foreach ($rows as $row){
        fputcsv($file, $row);
    }
    fclose($file);

}

足球编码：

问题并不难，但是首先您需要了解CSV中的代码。

这些可以在这里找到： http://www.football-data.co.uk/notes.txt，并且基于主场比赛和客场比赛。例如，如果您在第一行选择像尤文图斯这样的球队，您会看到他们在主场比赛，最终结果“ FTR”为“ H”，这意味着他们赢得了比赛。

您需要先掌握CSV编码，然后才能编写任何PHP！

编辑：应请求者的要求更改了实现，以作为单个HTML文件进行操作。

假设您已经设置了启用PHP的Web服务器，则可以将下面的代码粘贴到文件中并在浏览器中运行。就我而言，我调用了文件test.php并通过在浏览器中键入URL localhost:8080/test.php来运行它。您需要在网站主目录中拥有两个文件test.php和Results.csv。我有运行IISExpress的浏览器，监听8080端口。
