$_SERVER['REQUEST_URI']
For more details on what info is available in the $_SERVER array, see the PHP manual page for it.
有关 $_SERVER 数组中可用信息的更多详细信息，请参阅PHP 手册页。
If you also need the query string (the bit after the ?in a URL), that part is in this variable:
如果您还需要查询字符串（?URL 中的后面的位），则该部分在此变量中：
$_SERVER['QUERY_STRING']

if you want just the parts of url after http://domain.com, try this:
如果您只想要http://domain.com之后的 url 部分，请尝试以下操作：
<?php echo $_SERVER['REQUEST_URI']; ?>
if the current url was http://domain.com/some-slug/some-id, echo will return only '/some-slug/some-id'.
如果当前 url 是http://domain.com/some-slug/some-id，echo 将只返回 '/some-slug/some-id'。
if you want the full url, try this:
如果你想要完整的网址，试试这个：
<?php echo 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>

$uri = $_SERVER['REQUEST_URI'];
This will give you the requested directory and file name. If you use mod_rewrite, this is extremely useful because it tells you what page the user was looking at.
这将为您提供请求的目录和文件名。如果您使用 mod_rewrite，这将非常有用，因为它会告诉您用户正在查看的页面。
If you need the actual file name, you might want to try either $_SERVER['PHP_SELF'], the magic constant __FILE__, or $_SERVER['SCRIPT_FILENAME']. The latter 2 give you the complete path (from the root of the server), rather than just the root of your website. They are useful for includes and such.
如果您需要实际的文件名，您可能想要尝试$_SERVER['PHP_SELF']魔术常量__FILE__或$_SERVER['SCRIPT_FILENAME']。后两个为您提供完整路径（从服务器的根目录），而不仅仅是您网站的根目录。它们对于包含等很有用。
$_SERVER['PHP_SELF']gives you the file name relative to the root of the website.
$_SERVER['PHP_SELF']为您提供相对于网站根目录的文件名。
$relative_path = $_SERVER['PHP_SELF'];
$complete_path = __FILE__;
$complete_path = $_SERVER['SCRIPT_FILENAME'];

The other answers are correct. However, a quick note: if you're looking to grab the stuff after the ?in a URI, you should use the $_GET[]array.
其他答案都是正确的。但是，请注意：如果您想?在 URI之后获取内容，则应该使用$_GET[]数组。

You can use $_SERVER['HTTP_REFERER']this will give you whole URL for example:
您可以使用$_SERVER['HTTP_REFERER']它为您提供完整的 URL，例如：
suppose you want to get url of site name www.example.comthen $_SERVER['HTTP_REFERER']will give you https://www.example.com
假设您想获取网站名称的网址，www.example.com然后$_SERVER['HTTP_REFERER']会给您https://www.example.com
