Beispiele für URL: https://example.com/subFolder/yourfile.php?var=blabla#12345

typische PHP-Codes:

//built-in function 
$x = parse_url($url);
$x['scheme']               🡺 https
$x['host']                 🡺       example.com (or with WWW)
$x['path']                 🡺                  /subFolder/yourfile.php
$x['query']                🡺                                          var=blabla
$x['fragment']             🡺                                                     12345 // hashtag outputed only in case, when hashtag-containing string was manually passed to function, otherwise PHP is unable to recognise hashtags in $_SERVER

//built-in function  (with this function, I only recommend to pass `parse_url`s output as argument)
$A = pathinfo($url);
$B = pathinfo(parse_url($url)['path']);
$A['dirname']              🡺 https://example.com/subFolder

Beachten!:

• hastag (# ...) URL Teile können nicht von PHP (serverseitig) erkannt werden. Verwenden Sie dazu Javascript.
• DIRECTORY_SEPARATOR gibt \ für Windows-Host-Typen anstelle von / .

Für 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/  

Einfach verwenden:

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

Gleiche Technik wie die angenommene Antwort, aber mit HTTPS Unterstützung und besser lesbar:

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

Hier ist meine Lösung - der Code wurde von Tracy Debugger inspiriert. Es wurde geändert, um verschiedene Serverports zu unterstützen. Sie können die vollständige aktuelle URL einschließlich $_SERVER['REQUEST_URI'] oder nur die grundlegende Server-URL $_SERVER['REQUEST_URI'] . Prüfe meine Funktion:

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);
    }
}

Hier ist der Testcode:

// 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/

Ich habe diese Funktion gemacht, um die URL zu behandeln:

 <?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;
     }
 ?>

Meine bevorzugte Cross-Plattform-Methode zum Auffinden der aktuellen URL ist:

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

Schauen Sie sich $_SERVER['REQUEST_URI'] , d

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

(Beachten Sie, dass die String-Syntax in doppelten Anführungszeichen vollkommen korrekt ist )

Wenn Sie sowohl HTTP als auch HTTPS unterstützen möchten, können Sie verwenden

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

Anmerkung des Herausgebers: Die Verwendung dieses Codes hat Auswirkungen auf die Sicherheit . Der Client kann HTTP_HOST und REQUEST_URI auf einen beliebigen beliebigen Wert setzen.

Versuche dies:

$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;

Versuche dies:

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)

Dies funktioniert sowohl für HTTP als auch für HTTPS.

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

Gib so etwas aus.

https://example.com/user.php?token=3f0d9sickc0flmg8hnsngk5u07&access_level=application

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();

Demo

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.

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;
?>

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'];
}

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

$url = http_build_url();

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

Für mehr: https://codeupweb.wordpress.com/2017/10/11/how-to-get-the-full-url-of-page-using-php/

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

Above line store full URL in the variable $url. It includes https/http, subdomain, domain requested page.
