Как найти full url

Have a look at $_SERVER['REQUEST_URI'], i.e.

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

(Note that the double quoted string syntax is perfectly correct.)

If you want to support both HTTP and HTTPS, you can use

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

⚠️ Using this code has security implications because the client can set HTTP_HOST and REQUEST_URI to arbitrary values. It is absolutely necessary to sanitize both values and do meaningful input validation.

Short version to output link on a webpage

$url =  "//{$_SERVER['HTTP_HOST']}{$_SERVER['REQUEST_URI']}";

$escaped_url = htmlspecialchars( $url, ENT_QUOTES, 'UTF-8' );
echo '<a href="' . $escaped_url . '">' . $escaped_url . '</a>';

Here are some more details about the issues and edge cases of the //example.com/path/ format

Full version

function url_origin( $s, $use_forwarded_host = false )
{
    $ssl      = ( ! empty( $s['HTTPS'] ) && $s['HTTPS'] == 'on' );
    $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     = ( $use_forwarded_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;
    return $protocol . '://' . $host;
}

function full_url( $s, $use_forwarded_host = false )
{
    return url_origin( $s, $use_forwarded_host ) . $s['REQUEST_URI'];
}

$absolute_url = full_url( $_SERVER );
echo $absolute_url;

This is a heavily modified version of http://snipplr.com/view.php?codeview&id=2734 (Which no longer exists)

URL structure:

scheme://username:password@domain:port/path?query_string#fragment_id

The parts in bold will not be included by the function

Notes:

• This function does not include username:password from a full URL or the fragment (hash).
• It will not show the default port 80 for HTTP and port 443 for HTTPS.
• Only tested with http and https schemes.
• The #fragment_id is not sent to the server by the client (browser) and will not be added to the full URL.
• $_GET will only contain foo=bar2 for an URL like /example?foo=bar1&foo=bar2.
• Some CMS’s and environments will rewrite $_SERVER['REQUEST_URI'] and return /example?foo=bar2 for an URL like /example?foo=bar1&foo=bar2, use $_SERVER['QUERY_STRING'] in this case.
• Keep in mind that an URI = URL + URN, but due to popular use, URL now means both URI and URL.
• You should remove HTTP_X_FORWARDED_HOST if you do not plan to use proxies or balancers.
• The spec says that the Host header must contain the port number unless it is the default number.

Client (Browser) controlled variables:

• $_SERVER['REQUEST_URI']. Any unsupported characters are encoded by the browser before they are sent.
• $_SERVER['HTTP_HOST'] and is not always available according to comments in the PHP manual: http://php.net/manual/en/reserved.variables.php
• $_SERVER['HTTP_X_FORWARDED_HOST'] gets set by balancers and is not mentioned in the list of $_SERVER variables in the PHP manual.

Server controlled variables:

• $_SERVER['HTTPS']. The client chooses to use this, but the server returns the actual value of either empty or “on”.
• $_SERVER['SERVER_PORT']. The server only accepts allowed numbers as ports.
• $_SERVER['SERVER_PROTOCOL']. The server only accepts certain protocols.
• $_SERVER['SERVER_NAME'] . It is set manually in the server configuration and is not available for IPv6 according to kralyk.

Notice!

• The hashtag # parts were manually used in the above example just for illustration purposes, however, server-side languages (including PHP) can’t natively detect them (only JavaScript can do that, as the hashtag is only browser/client side functionality).
• DIRECTORY_SEPARATOR returns for Windows-type hosting, instead of /.

For 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/

Here’s a solution using a ternary statement, keeping the code minimal:

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

This is the smallest and easiest way to do this, assuming one’s web server is using the standard port 443 for HTTPS.

My favorite cross platform method for finding the current URL is:

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

Simply use:

$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;
}

Note: I just made an update to Timo Huovinen’s code, so you won’t get any GET parameters in the URL. This URL is plain and removes things like ?hi=i&am=a&get.

Example:

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

will be shown as:

http://www.example.com/index

This is fine unless you use GET paramaters to define some specific content, in which case you should use his code! 🙂

Same technique as the accepted answer, but with HTTPS support, and more readable:

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

The above gives unwanted slashes. On my setup Request_URI has leading and trailing slashes. This works better for me.

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

Here is my solution – code is inspired by Tracy Debugger. It was changed for supporting different server ports. You can get full current URL including $_SERVER['REQUEST_URI'] or just the basic server URL. Check my function:

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);
    }
}

Here is test code:

// 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/

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;
?>

Try this:

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();

Use this one-liner to find the parent folder URL (if you have no access to http_build_url() that comes along with pecl_http):

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

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();

Very simple use:

function current_url() {
    $current_url  = ( $_SERVER["HTTPS"] != 'on' ) ? 'http://'.$_SERVER["SERVER_NAME"] :  'https://'.$_SERVER["SERVER_NAME"];
    $current_url .= ( $_SERVER["SERVER_PORT"] != 80 ) ? ":".$_SERVER["SERVER_PORT"] : "";
    $current_url .= $_SERVER["REQUEST_URI"];

    return $current_url;
}

Use:

$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. 

Source: PHP Document Root, Path and URL detection

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'];
}
