PHP改变数据库的输出

Question

我正在创建一个显示在表格中的计算机清单网站.我正在尝试更改输出显示,例如以下内容

echo "<td>".$row['WindowsVersion']."</td>\n";

显示5.0或5.1或5.2或6.0或6.1

但我想要它显示

5.0 as 2000
5.1 as XP
5.2 as 2003
6.0 as Vista
6.1 as 7

任何帮助将不胜感激

Answer 1

您始终可以使用Windows版本作为此类的密钥创建预定义的阵列.

$win_ver = array('5.0' => '2000','5.1' => 'XP');

echo $win_ver[$row['WindowsVersion']];

Answer 2

数据库版本:

SELECT
    CASE WindowsVersion
    WHEN '5.0' THEN '2000'
    WHEN '5.1' THEN 'XP'
    WHEN '5.2' THEN '2003'
    WHEN '6.0' THEN 'Vista'
    ELSE '7' AS WindowsVersion
FROM ...

还是PHP

<?php
function getWinName($win) {
    switch($win) {
        case '5.0': $version = '2000'; break;
        case '5.1': $version = 'XP'; break;
        case '5.2': $version = '2003'; break;
        case '5.0': $version = 'Vista'; break;
        default: $version = '7';
    }
    return $version;
}

echo "" . getWinName($row['WindowsVersion']) . "\n";

Answer 3

在这种情况下,您可以使用数组作为显示/重写映射:

$rewrite = array(
  "5.0" => "2000",
  "5.1" => "XP",
  ..
);

print $rewrite[ $row['WindowsVersion'] ];

它只是将您的原始值用作重写数组中的索引键,并为您获取相关的替代值.
