PHP:如何获取已使用mod_rewrite重写的URL? [英] PHP: How can I get the URL that has been rewritten with mod_rewrite?

问题描述

例如，如果我将/category/topic/post/重写为/index.php?cat=1&topic=2&post=3，如何使用PHP获得/index.php?cat=1&topic=2&post=3?

For example, if I rewrite /category/topic/post/ to /index.php?cat=1&topic=2&post=3, how can I get /index.php?cat=1&topic=2&post=3 using PHP?

推荐答案

您可以轻松地重新创建它. $_SERVER['PHP_SELF']仍会为您提供脚本的正确文件名.这应该可以解决问题:

You can recreate it pretty easily. $_SERVER['PHP_SELF'] will still give you the correct file name for the script. This should do the trick:

$url = $_SERVER['PHP_SELF'];
$parts = array();
foreach( $_GET as $k=>$v ) {
    $parts[] = "$k=" . urlencode($v);
}

$url .= "?" . implode("&", $parts);

$url现在将成为您要查找的URL.

$url will now be the URL you're looking for.
