我正在寻找一种更高效、更优雅、更安全的方式来对 HTML 表中显示的数据进行排序。到目前为止，这是我想出的，它看起来有些臃肿/笨拙。

我还想到了类似将排序存储在 a 中的方法$_SESSION，这样我就不必在 URL 中“手动”将当前选择的订单带到下一页。也许一段“安全&简单”的 JavaScript+PHP（但请不要使用框架）会有意义吗？我的想法现在转了几个小时。

<?php
$ro_arr = array(
    "kid" => "kid",
    "kwd" => "Keyword",
    "cpc" => "ApproximateCPC",
    "cmp" => "Competition",
    "mov" => "MonthlyValue",
    "gms" => "GlobalMonthlySearches",
    "lms" => "LocalMonthlySearches",
    "dfc" => "KeywordDifficulty",
    "com" => "com",
    "net" => "net",
    "org" => "org",
    );

if (!empty($_GET['ro']) && strlen($_GET['ro']) == 7 && array_key_exists($col = substr($_GET['ro'], 0, 3), $ro_arr)) {
    $dir = (substr($_GET['ro'], 4, 3) == 'asc' ? "ASC" : "DESC");
    $res_order = $res_arr[''. $col .''] ." ". $dir;

} else {
    $_GET['ro'] = "kid_asc";
    $res_order = "kid ASC";
}
?>

<!-- just for testing -->
<pre><?php echo $res_order; ?></pre>
<!-- done testing -->

<table>
  <tr>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='kwd_asc')?"kwd_dsc":"kwd_asc"; ?>">Keyword</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='cmp_dsc')?"cmp_asc":"cmp_dsc"; ?>">Comp.</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='cpc_dsc')?"cpc_asc":"cpc_dsc"; ?>">Ad CPC</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='mov_dsc')?"mov_asc":"mov_dsc"; ?>">Value</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='gms_dsc')?"gms_asc":"gms_dsc"; ?>">Global Searches</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='lms_dsc')?"lms_asc":"lms_dsc"; ?>">Local Searches</a></td>
    <td><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='dfc_asc')?"dfc_dsc":"dfc_asc"; ?>">Difficulty</a></td>
    <td width="22"><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='com_dsc')?"com_asc":"com_dsc"; ?>">com</a></td>
    <td width="22"><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='net_dsc')?"net_asc":"net_dsc"; ?>">net</a></td>
    <td width="22"><a href="sort.v1.php?ro=<?php echo ($_GET['ro']=='org_dsc')?"org_asc":"org_dsc"; ?>">org</a></td>
  </tr>
</table>

如果您使用两个参数而不是一个参数，您可以将代码量减少到近一半：

  1. 您排序的参数：kid, com, net, org...
  2. 顺序：asc、dsc

如果您的表格不是太大并且您不反对使用jQuery，请使用tablsorter。一旦进入数千行，客户端排序就会变得有点笨拙。
