// 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;

...is my most resilient routine for this.

You might like to try:

您可能想尝试：

echo '<pre>';
print_r($_SERVER);
echo '</pre>';

A combination of $_SERVER['HTTP_HOST']and $_SERVER['SCRIPT_NAME']or $_SERVER['PHP_SELF']should be what you are looking for.

的组合$_SERVER['HTTP_HOST']和$_SERVER['SCRIPT_NAME']或$_SERVER['PHP_SELF']应该是你在找什么。

You need to build it yourself;

您需要自己构建它；

echo $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

You can also use $_SERVER['HTTPS']to detect if HTTP or HTTPS.

您还可以使用$_SERVER['HTTPS']来检测 HTTP 还是 HTTPS。

I recommend using $_SERVER['REQUEST_URI']as this is exactly what the user is looking for, before any rewrites or anything else, and includes GET variables

我建议使用，$_SERVER['REQUEST_URI']因为这正是用户正在寻找的，在任何重写或其他任何事情之前，并且包括 GET 变量

There is no full url contain in $_SERVER. But you can use this code:

$_SERVER 中不包含完整的 url。但是您可以使用以下代码：

$url = "http://" . $_SERVER['HTTP_HOST'] . "/" . $_SERVER['PHP_SELF'] . "/" . $_SERVER['QUERYSTRING'] . "/";
