我使用此代码获取完整的URL:
$actual_link = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
问题是我在我.htaccess身上使用了一些掩码,所以我们在URL中看到的并不总是文件的真实路径.
我需要的是获取URL,URL中写的内容,仅此而已 - 完整的URL.
我需要了解它在Web浏览器的导航栏中的显示方式,而不是服务器上文件的真实路径.

看看$_SERVER['REQUEST_URI'],即
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
(请注意,双引号字符串语法完全正确)
如果要同时支持HTTP和HTTPS,则可以使用
$actual_link = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
编者注:使用此代码具有安全隐患.客户端可以将HTTP_HOST和REQUEST_URI设置为它想要的任意值.

这是一个使用三元语句的解决方案,保持代码最小化:
$url = "http" . (($_SERVER['SERVER_PORT'] == 443) ? "s" : "") . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
假设一个人的Web服务器使用HTTPS的标准端口443,这是最小和最简单的方法.

我最喜欢的用于查找当前URL的跨平台方法是:
$url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
Hap*_*der 32
只需使用:
$uri = $_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']
Ale*_*ard 20
function full_path()
{
$s = &$_SERVER;
$ssl = (!empty($s['HTTPS']) && $s['HTTPS'] == 'on') ? true:false;
$sp = strtolower($s['SERVER_PROTOCOL']);
$protocol = substr($sp, 0, strpos($sp, '/')) . (($ssl) ? 's' : '');
$port = $s['SERVER_PORT'];
$port = ((!$ssl && $port=='80') || ($ssl && $port=='443')) ? '' : ':'.$port;
$host = isset($s['HTTP_X_FORWARDED_HOST']) ? $s['HTTP_X_FORWARDED_HOST'] : (isset($s['HTTP_HOST']) ? $s['HTTP_HOST'] : null);
$host = isset($host) ? $host : $s['SERVER_NAME'] . $port;
$uri = $protocol . '://' . $host . $s['REQUEST_URI'];
$segments = explode('?', $uri, 2);
$url = $segments[0];
return $url;

注意:我刚刚对"Timo Huovinen"代码进行了更新,因此您不会在URL中获得任何内容.这个网址很简单,删除了"？hi = i&am = a&get"之类的内容.
例:
http://www.example.com/index?get=information
将显示为:
http://www.example.com/index
除非您使用Get来定义某些特定内容,否则请使用他的代码!:-)

清除代码,适用于所有Web服务器(Apache,nginx,IIS,...):

Ozz*_*ech 11
这是我的解决方案 - 代码的灵感来自Tracy Debugger.它被更改为支持不同的服务器端口.您可以获取完整的当前URL,包括$_SERVER['REQUEST_URI']基本服务器URL.检查我的功能:
function getCurrentUrl($full = true) {
if (isset($_SERVER['REQUEST_URI'])) {
$parse = parse_url(
(isset($_SERVER['HTTPS']) && strcasecmp($_SERVER['HTTPS'], 'off') ? 'https://' : 'http://') .
(isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : (isset($_SERVER['SERVER_NAME']) ? $_SERVER['SERVER_NAME'] : '')) . (($full) ? $_SERVER['REQUEST_URI'] : null)
);
$parse['port'] = $_SERVER["SERVER_PORT"]; // Setup protocol for sure (80 is default)
return http_build_url('', $parse);
}
}
这是测试代码:
// Follow $_SERVER variables was set only for test
$_SERVER['HTTPS'] = 'off'; // on
$_SERVER['SERVER_PORT'] = '9999'; // Setup
$_SERVER['HTTP_HOST'] = 'some.crazy.server.5.name:8088'; // Port is optional there
$_SERVER['REQUEST_URI'] = '/150/tail/single/normal?get=param';
echo getCurrentUrl();
// http://some.crazy.server.5.name:9999/150/tail/single/normal?get=param
echo getCurrentUrl(false);
// http://some.crazy.server.5.name:9999/

我已经使用此函数来处理URL:
<?php
function curPageURL()
{
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
$pageURL .=
$_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
}
else {
$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;
}
?>
与接受的答案相同的技术,但支持HTTPS,更具可读性:
$current_url = sprintf(
'%s://%s/%s',
isset($_SERVER['HTTPS']) ? 'https' : 'http',
$_SERVER['HTTP_HOST'],
$_SERVER['REQUEST_URI']
);
HTTP_HOST和REQUEST_URI必须在引号中,否则会在PHP 7.2中引发错误
使用:
$actual_link = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
如果要同时支持HTTP和HTTPS:
$actual_link = (isset($_SERVER['HTTPS']) ? 'https' : 'http').'://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

使用此单行查找父文件夹URL(如果您无权访问pecl_http附带的http_build_url()):
$url = (isset($_SERVER['HTTPS']) ? 'https://' : 'http://').$_SERVER['SERVER_NAME'].str_replace($_SERVER['DOCUMENT_ROOT'], '', dirname(dirname(__FILE__)));
小智 6
这对您的Apache环境变量来说非常容易.这仅适用于Apache 2,我假设您正在使用它.
只需使用以下PHP代码:
<?php
$request_url = apache_getenv("HTTP_HOST") . apache_getenv("REQUEST_URI");
echo $request_url;
?>
试试这个:
print_r($_SERVER);
$_SERVER是一个包含标题,路径和脚本位置等信息的数组.此阵列中的条目由Web服务器创建.无法保证每个Web服务器都能提供这些服务; 服务器可以省略一些,或提供此处未列出的其他服务器.也就是说,在»CGI/1.1规范中考虑了大量这些变量,因此您应该能够期待这些变量.
$HTTP_SERVER_VARS包含相同的初始信息,但不是超全局.(注意,$HTTP_SERVER_VARS并且$_SERVER是不同的变量,PHP会这样处理它们)
您可以使用不带参数的http_build_url来获取当前页面的完整URL:
$url = http_build_url();
我已经让这个类来处理我的URI了

当然,你必须根据自己的需求和系统进行调整!？!

它仍然需要完善,但它是集中式URI系统的神解决方案:D
这是您的问题的解决方案：
//Fetch page URL by this
$url = $_SERVER['REQUEST_URI'];
echo "$url<br />";
//It will print
//fetch host by this
$host=$_SERVER['HTTP_HOST'];
echo "$host<br />";
//You can fetch the full URL by this
$fullurl = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
echo $fullurl;
