PHP和调用url？ [英] PHP and invoking url?

问题描述

可能重复：

获取当前网址

我不想使用网址（任何GET） PHP代码中的参数等。

I wan't to use url (with any GET parameters, etc) in PHP code.

所以当我的网站在url上时：http：/sample.com/art/id/title我想在这里显示这个字符串网站。

So when my website is on url: http:/sample.com/art/id/title I want to display this string in website.

还有一件事......我的代码会在具有各种url约定的各种服务器上启动。

There is also one thing... My code would be fired up on various servers with various url conventions.

推荐答案

// Get HTTP/HTTPS (the possible values for this vary from server to server)
$myUrl = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] && !in_array(strtolower($_SERVER['HTTPS']),array('off','no'))) ? 'https' : 'http';
// Get domain portion
$myUrl .= '://'.$_SERVER['HTTP_HOST'];
// Get path to script
$myUrl .= $_SERVER['REQUEST_URI'];
// Add path info, if any
if (!empty($_SERVER['PATH_INFO'])) $myUrl .= $_SERVER['PATH_INFO'];
// Add query string, if any (some servers include a ?, some don't)
if (!empty($_SERVER['QUERY_STRING'])) $myUrl .= '?'.ltrim($_SERVER['REQUEST_URI'],'?');

echo $myUrl;

应考虑您可能遇到的任何变化（尽管mod_rewrite可能会将其搞砸可纠正的方式，我不确定。）

Should account for just about any variations you might encounter (although mod_rewrite may screw it up in an un-correctable way, I'm not sure).
