Посмотрите на $_SERVER['REQUEST_URI'] , т.е.

 $actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; 

(Обратите внимание, что синтаксис с двойными кавычками является абсолютно правильным )

Если вы хотите поддерживать HTTP и HTTPS, вы можете использовать

 $actual_link = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; 

Примечание редактора: использование этого кода имеет последствия для безопасности . Клиент может установить HTTP_HOST и REQUEST_URI для любого произвольного значения, которое он хочет.

Короткая версия для вывода ссылки на веб-странице

 $url = "//{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}"; $escaped_url = htmlspecialchars( $url, ENT_QUOTES, 'UTF-8' ); echo '<a href="' . $escaped_url . '">' . $escaped_url . '</a>';

Структура URL:

Схема: // имя пользователя: пароль @domain: порт / путь? query_string # fragment_id

Части, выделенные жирным шрифтом, не будут включены функцией

Заметки:

• Эта функция не включает username:password из полного URL-адреса или фрагмента (хэша).
• Он не будет показывать порт 80 по умолчанию для HTTP и порт 443 для HTTPS.
• Проверяется только с помощью схем http и https.
• #fragment_id не отправляется сервером клиентом (браузером) и не будет добавлен к полному URL-адресу.
• $_GET будет содержать только foo=bar2 для URL, например, /example?foo=bar1&foo=bar2 .
• Некоторые CMS и среды будут переписывать $_SERVER['REQUEST_URI'] и возвращать /example?foo=bar2 для URL-адреса, например /example?foo=bar1&foo=bar2 , в этом случае использовать $_SERVER['QUERY_STRING'] .
• Имейте в виду, что URI = URL + URN , но из-за популярного использования URL теперь означает URI и URL.
• Вы должны удалить HTTP_X_FORWARDED_HOST если вы не планируете использовать прокси или балансиры.
• Спецификация говорит, что заголовок Host должен содержать номер порта, если он не является номером по умолчанию.

Контролируемые клиентом (Browser) переменные:

• $_SERVER['REQUEST_URI'] . Любые неподдерживаемые символы кодируются браузером до их отправки.
• $_SERVER['HTTP_HOST'] и не всегда доступен в соответствии с комментариями в руководстве по PHP: http://php.net/manual/en/reserved.variables.php
• $_SERVER['HTTP_X_FORWARDED_HOST'] устанавливается балансирами и не упоминается в списке переменных $_SERVER в руководстве PHP.

Управляемые сервером переменные:

• $_SERVER['HTTPS'] . Клиент решает использовать это, но сервер возвращает фактическое значение либо пустого, либо «включен».
• $_SERVER['SERVER_PORT'] . Сервер допускает только разрешенные номера в качестве портов.
• $_SERVER['SERVER_PROTOCOL'] . Сервер принимает только определенные протоколы.
• $_SERVER['SERVER_NAME'] . Он устанавливается вручную в конфигурации сервера и недоступен для IPv6 в соответствии с kralyk .

В этом отношении просто взгляните на весь массив с print_r($_SERVER) , вы увидите все, что вам нужно там 🙂

Обратите внимание !:

• hastag (# …) детали url не могут быть обнаружены с PHP (на стороне сервера). Для этого используйте Javascript.
• DIRECTORY_SEPARATOR возвращает \ для хостов Windows-типа вместо / .

Для WordPress

 //(let's say, if wordpress is installed in subdirectory: http://example.com/wpdir/) home_url() 🡺 http://example.com/wpdir/ //if is_ssl() is true, then it will be "https" get_stylesheet_directory_uri() 🡺 http://example.com/wpdir/wp-content/themes/THEME_NAME [same: get_bloginfo('template_url') ] get_stylesheet_directory() 🡺 /home/user/public_html/wpdir/wp-content/themes/THEME_NAME plugin_dir_url(__FILE__) 🡺 http://example.com/wpdir/wp-content/themes/PLUGIN_NAME plugin_dir_path(__FILE__) 🡺 /home/user/public_html/wpdir/wp-content/plugins/PLUGIN_NAME/ 

Вот решение, использующее тройную инструкцию , сохраняя код минимальным:

 $url = "http" . (($_SERVER['SERVER_PORT'] == 443) ? "s://" : "://") . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; 

Это самый маленький и простой способ сделать это, предполагая, что веб-сервер использует стандартный порт 443 для HTTPS .

Мой любимый кросс-платформенный метод для поиска текущего URL-адреса:

 $url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]"; 

Просто используйте:

 $uri = $_SERVER['REQUEST_SCHEME'] . '://' . $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'] 

 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; } , 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; } 

Примечание. Я только что обновил код «Timo Huovinen», поэтому вы не получите доступ к URL-адресу. Этот URL-адрес является простым и удаляет такие вещи, как «? Hi = i & am = a & get».

Пример:

 http://www.website.com/index?get=information 

будет отображаться как:

 http://www.website.com/index 

Если вы не используете Get's для определения определенного контента, используйте его код! 🙂

Очистить код, работающий во всех веб-серверах (Apache, nginx, IIS, …):

 $url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https' : 'http') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; 

Вот мое решение – код вдохновлен Tracy Debugger . Он был изменен для поддержки разных серверных портов. Вы можете получить полный текущий URL, включая $_SERVER['REQUEST_URI'] или только основной URL-адрес сервера. Проверьте мою функцию:

 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); } } 

Вот тестовый код:

 // 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/ 

Я использовал эту функцию для обработки URL-адреса:

  <?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; } ?> 

Тот же метод, что и принятый ответ, но с поддержкой HTTPS и более читаемым:

 $current_url = sprintf( '%s://%s/%s', isset($_SERVER['HTTPS']) ? 'https' : 'http', $_SERVER['HTTP_HOST'], $_SERVER['REQUEST_URI'] ); 

Используйте этот однострочный интерфейс для поиска URL родительской папки (если у вас нет доступа к http_build_url (), который поставляется вместе с pecl_http):

 $url = (isset($_SERVER['HTTPS']) ? 'https://' : 'http://').$_SERVER['SERVER_NAME'].str_replace($_SERVER['DOCUMENT_ROOT'], '', dirname(dirname(__FILE__))); 

Я сделал этот класс для обработки своих URI

Of course you have to adapt it to your needs and system !?!

 <?php // Change a few parameters before loading the class. $_URI_Params = array( 'Public_Relative' => FALSE, 'Skin_Relative' => FALSE, 'Skin_Default' => 'classic', // etc. ); // Get the URI class require('uri.php'); // Output all extracted URI segments echo '<pre>'; var_dump(_URI::Extract()); echo '</pre>'; // Output extracted segments individually echo 'Scheme: '._URI::Segment('SCHEME').'<br/>'; echo 'User: '._URI::Segment('USER').'<br/>'; echo 'Password: '._URI::Segment('PASSWD').'<br/>'; echo 'Host: '._URI::Segment('HOST').'<br/>'; echo 'Port: '._URI::Segment('PORT').'<br/>'; echo 'Path: '._URI::Segment('PATH').'<br/>'; echo 'Script: '._URI::Segment('SCRIPT').'<br/>'; echo 'Info: '._URI::Segment('INFO').'<br/>'; // Compile extracted segments into a usable URL echo '<br/>'; echo 'Full Compiled URI: '._URI::Compile().'<br/>'; echo '<br/>'; // Output precompiled common bases for a faster result and better performance echo 'Host Base: '._URI::Base('Host').'<br/>'; echo 'Application Base: '._URI::Base('App').'<br/>'; echo 'Running Script: '._URI::Base('Script').'<br/>'; echo 'Current URI Base: '._URI::Base('Current').'<br/>'; echo 'Public Folder Base: '._URI::Base('Public').'<br/>'; echo 'Skin Folder Base: '._URI::Base('Skin').'<br/>'; // Get all the precompiled bases in an associative array echo '<pre>'; var_dump(_URI::Base('All')); echo '</pre>'; // Parse an example string and replace known keys with actual URI data. echo _URI::Parse('This is my current domain: %HostBase% And the current application is here: %AppBase% I load my skins form: %SkinBase% etc. '); 

It still needs to be perfected but it's a god solution for a centralized URI system 😀

This is quite easy to do with your Apache environment variables. This only works with Apache 2, which I assume you are using.

Simply use the following PHP code:

 <?php $request_url = apache_getenv("HTTP_HOST") . apache_getenv("REQUEST_URI"); echo $request_url; ?> 

This is the solution for your problem:

 //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; 

I used this statement.

 $base = "http://$_SERVER[SERVER_NAME]:$_SERVER[SERVER_PORT]$my_web_base_path"; $url = $base . "/" . dirname(dirname(__FILE__)); 

I hope this will help you.

Попробуй это:

 print_r($_SERVER); 

$_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server. There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here. That said, a large number of these variables are accounted for in the » CGI/1.1 specification, so you should be able to expect those.

$HTTP_SERVER_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_SERVER_VARS and $_SERVER are different variables and that PHP handles them as such)

You can use http_build_url with no arguments to get the full URL of the current page:

 $url = http_build_url(); 

Попробуй это:

 $pageURL = $_SERVER['HTTPS'] == 'on' ? 'https://' : 'http://'; $pageURL .= $_SERVER['SERVER_PORT'] != '80' ? $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"] : $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; echo $pageURL; 

I have used the below code, and it is working fine for me, for both cases, HTTP and HTTPS.

 function curPageURL() { if(isset($_SERVER["HTTPS"]) && !empty($_SERVER["HTTPS"]) && ($_SERVER["HTTPS"] != 'on' )) { $url = 'https://'.$_SERVER["SERVER_NAME"];//https url } else { $url = 'http://'.$_SERVER["SERVER_NAME"];//http url } if(( $_SERVER["SERVER_PORT"] != 80 )) { $url .= $_SERVER["SERVER_PORT"]; } $url .= $_SERVER["REQUEST_URI"]; return $url; } echo curPageURL();

 $base_dir = __DIR__; // Absolute path to your installation, ex: /var/www/mywebsite $doc_root = preg_replace("!{$_SERVER['SCRIPT_NAME']}$!", '', $_SERVER['SCRIPT_FILENAME']); # ex: /var/www $base_url = preg_replace("!^{$doc_root}!", '', $base_dir); # ex: '' or '/mywebsite' $base_url = str_replace('\\', '/', $base_url);//On Windows $base_url = str_replace($doc_root, '', $base_url);//On Windows $protocol = empty($_SERVER['HTTPS']) ? 'http' : 'https'; $port = $_SERVER['SERVER_PORT']; $disp_port = ($protocol == 'http' && $port == 80 || $protocol == 'https' && $port == 443) ? '' : ":$port"; $domain = $_SERVER['SERVER_NAME']; $full_url = "$protocol://{$domain}{$disp_port}{$base_url}"; # Ex: 'http://example.com', 'https://example.com/mywebsite', etc.

 $page_url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

You can make use of HTTP_ORIGIN as illustrated in the snippet below:

 if ( ! array_key_exists( 'HTTP_ORIGIN', $_SERVER ) ) { $this->referer = $_SERVER['SERVER_NAME']; } else { $this->referer = $_SERVER['HTTP_ORIGIN']; } 

I think this method is good..try it

 if($_SERVER['HTTP_HOST'] == "localhost"){ define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('SITEPATH', $_SERVER['DOCUMENT_ROOT']); define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/'); define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/'); } else{ define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('SITEPATH', $_SERVER['DOCUMENT_ROOT']); define('TEMPLATE', $_SERVER['DOCUMENT_ROOT'] . '/incs/template/'); define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/'); define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/'); } 

This works for both HTTP and HTTPS.

 echo 'http' . (($_SERVER['HTTPS'] == 'on') ? 's' : '') . '://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; 

Output something like this.
