如果我们的分数大于对手的分数，则显示获胜；如果我们的分数低于对手的分数，则显示失败

Question

我使用PHP输出斯坦福田径比分的XML提要，在这个例子中是男子篮球。其中两个属性是两支球队的得分，'hs‘是主场得分，' vs’是客队得分(例如，俄勒冈州立大学vs斯坦福大学的XML属性是: hs="67“vs="69")。'vn‘和’vn‘是本地名称和访问者名称(例如，'Stanford’或'Oregon State')。其他'hc‘和'vc’是本市和客市，并且包含城市名称的前4个字母(例如，Stanford将是'stan‘，'Oregon State’将是'oreg')。注意:因为Cat只有三个字母长，所以Cat is 'cat‘的hc和vc也是三个字母。

我的问题是，如果斯坦福分数大于对手分数，是否可以显示"Win“，或者如果斯坦福分数小于对手分数，是否可以显示"Loss”？例如，俄勒冈州立大学击败了斯坦福大学，那么我如何显示"at Oregon State - Loss"？

下面是我的page、XML和代码：

<?php
$xml = simplexml_load_file('http://www.gostanford.com/data/xml/events/m-baskbl/2010/index.xml');

// Reverse chronological order
$xmlArray = array();
foreach ($xml as $event_date) $xmlArray[] = $event_date;
$xmlArray = array_reverse($xmlArray);

foreach ($xmlArray as $event_date)
{
    // Only output if complete
    if(!empty($event_date->event['vn']) && !empty($event_date->event['hn']) && !empty($event_date->event['vs']) && !empty($event_date->event['hs']))
    {
    // Only show opponents' name
    $name = ($event_date->event['vc'] == 'stan') ? $event_date->event['hn'] : $event_date->event['vn'];
    // Output "vs" if home game or "at" if away game
    $preposition = ($event_date->event['hc'] == 'stan') ? 'vs' : 'at';
    echo '<li>';
        echo '<h3>', $preposition, ' ', $name, '</h3>';
        echo '<p><strong>', $event_date->event['vn'], ' ', $event_date->event['vs'], ' - ', $event_date->event['hn'], ' ', $event_date->event['hs'], '</strong></p>';
        echo '<p>', date('F j, Y', strtotime($event_date['date'])), '</p>';
    echo '</li>';
    }
}   
?>

Answer 1

$home = ($event_date->event['hc'] == 'stan');
echo '<h3>', $preposition, ' ', $name, ' - ', ((int)$event_date->event['hs'] == (int)$event_date->event['vs'] ? "Tie" : (((int)$event_date->event['hs'] > (int)$event_date->event['vs']) ? ($home? 'Win' : 'Loss') : ($home ? 'Loss' : 'Win'))), '</h3>';

把这些放到foreach循环中，我还添加了一个“领带”的东西。

通过定义$home变量，您可以替换以下行：

 // Only show opponents' name
 $name = ($event_date->event['vc'] == 'stan') ? $event_date->event['hn'] : $event_date->event['vn'];
// Output "vs" if home game or "at" if away game
$preposition = ($event_date->event['hc'] == 'stan') ? 'vs' : 'at';

有了这些：

// Home?
$home = ($event_date->event['hc'] == 'stan');
// Only show opponents' name
$name = $home ? $event_date->event['hn'] : $event_date->event['vn'];
// Output "vs" if home game or "at" if away game
$preposition = $home ? 'vs' : 'at';

并且您不需要在我编写的代码中使用$home。

下面是完整的代码：

<?php
$xml = simplexml_load_file('http://www.gostanford.com/data/xml/events/m-baskbl/2010/index.xml');

// Reverse chronological order
$xmlArray = array();
foreach ($xml as $event_date) $xmlArray[] = $event_date;
$xmlArray = array_reverse($xmlArray);

foreach ($xmlArray as $event_date)
{
    // Only output if complete
    if(!empty($event_date->event['vn']) && !empty($event_date->event['hn']) && !empty($event_date->event['vs']) && !empty($event_date->event['hs']))
    {
    // Home?
    $home = ($event_date->event['hc'] == 'stan');
    // Only show opponents' name
    $name = $home ? $event_date->event['vn'] : $event_date->event['hn'];
    // Output "vs" if home game or "at" if away game
    $preposition = $home ? 'vs' : 'at';
    echo '<li>';
        echo '<h3>', $preposition, ' ', $name, ' - ', ((int)$event_date->event['hs'] == (int)$event_date->event['vs'] ? "Tie" : (((int)$event_date->event['hs'] > (int)$event_date->event['vs']) ? ($home? 'Win' : 'Loss') : ($home ? 'Loss' : 'Win'))), '</h3>';
        echo '<p><strong>', $event_date->event['vn'], ' ', $event_date->event['vs'], ' - ', $event_date->event['hn'], ' ', $event_date->event['hs'], '</strong></p>';
        echo '<p>', date('F j, Y', strtotime($event_date['date'])), '</p>';
    echo '</li>';
    }
}   
?>

使用"if's“和更多注释扩展代码：

<?php
$xml = simplexml_load_file('http://www.gostanford.com/data/xml/events/m-baskbl/2010/index.xml');

// Reverse chronological order
$xmlArray = array();
foreach ($xml as $event_date) $xmlArray[] = $event_date;
$xmlArray = array_reverse($xmlArray);

foreach ($xmlArray as $event_date)
{
    // Only output if complete
    if(!empty($event_date->event['vn']) && !empty($event_date->event['hn']) && !empty($event_date->event['vs']) && !empty($event_date->event['hs']))
    {
    // Home?
    $home = ($event_date->event['hc'] == 'stan');
    // Only show opponents' name
    $name = $home ? $event_date->event['vn'] : $event_date->event['hn'];
    // Output "vs" if home game or "at" if away game
    $preposition = $home ? 'vs' : 'at';
    if((int)$event_date->event['hs'] == (int)$event_date->event['vs']) // Tie?
    {
    $result = 'Tie'; // Tie
    }
    else if((int)$event_date->event['hs'] > (int)$event_date->event['vs']) // Home team won?
    {
    if($home) // Home?
    {
    $result = 'Win'; // You're home and the home team won
    }
    else
    {
    $result = 'Loss'; // You're away, but the home team won
    }
    }
    else // Home team lost
    {
    if($home) // Home?
    {
    $result = 'Loss'; // You're away, but the home team won
    }
    else
    {
    $result = 'Win'; // You're home and the home team won
    }
    }
    echo '<li>';
        echo '<h3>', $preposition, ' ', $name, ' - ', $result, '</h3>';
        echo '<p><strong>', $event_date->event['vn'], ' ', $event_date->event['vs'], ' - ', $event_date->event['hn'], ' ', $event_date->event['hs'], '</strong></p>';
        echo '<p>', date('F j, Y', strtotime($event_date['date'])), '</p>';
    echo '</li>';
    }
}   
?>

Answer 2

假设$event_date->event['hs']是Home Score，$event_date->event['vs']是 is

echo ($event_date->event['hs'] > $event_date->event['vs']) ? 'WIN' : 'LOSS';

或者，如果有平局的可能性：

echo ($event_date->event['hs'] > $event_date->event['vs']) ? 'WIN' : ($event_date->event['hs'] < $event_date->event['vs']) ? 'LOSS' : 'TIE';

注意：此答案的输出完全基于主队。因为你需要它总是引用斯坦福大学，所以@Tyilo的答案是更好的匹配。
