用PHP读写一个包含锦标赛比赛结果的文本文件

Question

冠军联赛G组足球比赛结果：

RB莱比锡；AS摩纳哥；战平波尔图足球俱乐部；Besiktas JK；损失
Besiktas JK；莱比锡RB；赢得
AS摩纳哥；波尔图足球俱乐部；损失
AS摩纳哥；Besiktas JK；亏损
莱比锡RB；波尔图足球俱乐部；获胜
Besiktas JK；AS摩纳哥；战平波尔图足球俱乐部；莱比锡RB；获胜
Besiktas JK；波尔图足球俱乐部；抽签
AS摩纳哥；莱比锡RB；输给波尔图足球俱乐部；AS摩纳哥；赢得莱比锡RB；Besiktas JK；损失

1. 比赛结果指的是列出的第一支球队。

   (示例：
   贝西克塔斯JK；RB莱比锡；获胜

   • 意味着贝西克塔斯JK击败了莱比锡RB

   AS摩纳哥足球俱乐部；Besiktas JK；损失

   • 意味着贝西克塔斯队击败了AS摩纳哥队

   RB莱比锡；AS摩纳哥足球俱乐部；绘制

   • 意味着莱比锡RB和摩纳哥AS打平(

2. 一支球队获胜可得3分。平局得1分。亏损赚0。

3. 结果应按点数排序，降序。在平局的情况下，球队按字母顺序排列

输出应该是这样的：

Team                           | MP |  W |  D |  L |  P
Besiktas JK                    |  6 |  4 |  2 |  0 |  14
FC Porto                       |  6 |  3 |  1 |  2 |  10
RB Leipzig                     |  6 |  2 |  1 |  3 |  6
AS Monaco                      |  6 |  0 |  2 |  4 |  2

然而，我无法得到排名和客场胜利的结果。我该怎么做

Besiktas JK;RB Leipzig;win
AS Monaco;FC Porto;loss

foreach ($results as $result) {

}
$p = $w * 3 + $d;

}
fclose($fp);

我无法测试您的代码，因为我使用的是PHP 5.6.36版本。但是使用下面的代码，我从PHP 5中得到了结果。包括客场胜利。

<style type="text/css">
table       { border-spacing: 0px; }
table th    { padding: 5px; border: 1px solid black; }
table td    { padding: 3px; border: 1px solid dimgrey; }
</style>

<?
// Initialisation
$infoList = array("MP","W","Wext","D","L","P");
// Open File
$lines = file('tournament.txt');
// For Each Line
foreach ($lines as $line)
{
$parts = explode(';', $line);

// Extraction
$teamA    = $parts[0];
$teamB    = $parts[1];
$score    = $parts[2];
// Initialization
$teamList["$teamA"]["W"]      = 0;
$teamList["$teamA"]["Wext"] = 0;
$teamList["$teamA"]["L"]      = 0;
$teamList["$teamA"]["D"]      = 0;
$teamList["$teamA"]["P"]      = 0;
$teamList["$teamA"]["MP"]     = (array_key_exists("MP", $teamList["$teamA"]))?bcadd($teamList["$teamA"]["MP"],1,0):1;
// Initialization
$teamList["$teamB"]["W"]      = 0;
$teamList["$teamB"]["Wext"] = 0;
$teamList["$teamB"]["L"]      = 0;
$teamList["$teamB"]["D"]      = 0;
$teamList["$teamB"]["P"]      = 0;
$teamList["$teamB"]["MP"]     = (array_key_exists("MP", $teamList["$teamB"]))?bcadd($teamList["$teamB"]["MP"],1,0):1;

}
// End - For Each Line

// For Each Match
foreach($matchList as $matchKey => $matchValue)

if($matchValue["score"]=="win")
{

$teamList["".$matchValue["teamA"].""]["W"]  = bcadd($teamList["".$matchValue["teamA"].""]["W"],1,0);
$teamList["".$matchValue["teamA"].""]["P"]  = bcadd($teamList["".$matchValue["teamA"].""]["P"],3,0);

// If Team A Loss
if($matchValue["score"]=="loss")

$teamList["".$matchValue["teamB"].""]["P"]      = bcadd($teamList["".$matchValue["teamB"].""]["P"],3,0);

// If Equality

// Fin - For Each Match





// -------- Display in HTML -------- //

它可能看起来有点重，但它允许拥有一个包含所有必要信息的teamList数组
