Saya menggunakan kode ini untuk mendapatkan URL lengkap:

$actual_link = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];

Masalahnya adalah bahwa saya menggunakan beberapa topeng di saya .htaccess, jadi apa yang kita lihat di URL tidak selalu path sebenarnya dari file tersebut.

Yang saya butuhkan adalah mendapatkan URL, apa yang tertulis dalam URL, tidak lebih dan tidak kurang — URL lengkap.

Saya perlu mengetahui bagaimana tampilannya di Bilah Navigasi di browser web, dan bukan path sebenarnya dari file di server.

Lihatlah $_SERVER['REQUEST_URI'], yaitu

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

(Perhatikan bahwa sintaks string ganda yang dikutip benar sekali )

Jika Anda ingin mendukung HTTP dan HTTPS, Anda dapat menggunakan

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

Catatan editor: menggunakan kode ini memiliki implikasi keamanan . Klien dapat mengatur HTTP_HOST dan REQUEST_URI ke nilai sewenang-wenang yang diinginkannya.

Tautan versi singkat ke keluaran di laman web

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

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

Berikut adalah beberapa detail tentang masalah dan kasus tepi format //example.com/path/

    $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;

Struktur URL:

skema: // nama pengguna: kata sandi @ domain: port / path? query_string # fragment_id

Bagian yang dicetak tebal tidak akan dimasukkan oleh fungsi

Catatan:

• Fungsi ini tidak termasuk username:password dari URL lengkap atau fragmen (hash).
• Ini tidak akan menampilkan port default 80 untuk HTTP dan port 443 untuk HTTPS.
• Hanya diuji dengan skema http dan https.
• Itu #fragment_id tidak dikirim ke server oleh klien (browser) dan tidak akan ditambahkan ke URL lengkap.
• $_GEThanya akan berisi foo=bar2untuk URL seperti/example?foo=bar1&foo=bar2 .
• Beberapa CMS dan lingkungan akan menulis ulang $_SERVER['REQUEST_URI']dan kembali /example?foo=bar2untuk URL seperti /example?foo=bar1&foo=bar2, gunakan $_SERVER['QUERY_STRING']dalam kasus ini.
• Perlu diingat bahwa URI = URL + URN, tetapi karena penggunaan yang populer, URL sekarang berarti URI dan URL.
• Anda harus menghapus HTTP_X_FORWARDED_HOST jika Anda tidak berencana untuk menggunakan proxy atau penyeimbang.
• The spek mengatakan bahwa Hostsundulan harus berisi nomor port kecuali nomor default.

Variabel yang dikendalikan klien (Browser):

• $_SERVER['REQUEST_URI']. Setiap karakter yang tidak didukung dikodekan oleh browser sebelum dikirim.
• $_SERVER['HTTP_HOST']dan tidak selalu tersedia sesuai dengan komentar dalam manual PHP: http://php.net/manual/en/reserved.variables.php
• $_SERVER['HTTP_X_FORWARDED_HOST']diatur oleh penyeimbang dan tidak disebutkan dalam daftar $_SERVERvariabel dalam manual PHP.

Variabel yang dikendalikan server:

• $_SERVER['HTTPS']. Klien memilih untuk menggunakan ini, tetapi server mengembalikan nilai aktual kosong atau "pada".
• $_SERVER['SERVER_PORT']. Server hanya menerima nomor yang diizinkan sebagai port.
• $_SERVER['SERVER_PROTOCOL']. Server hanya menerima protokol tertentu.
• $_SERVER['SERVER_NAME']. Sudah diatur secara manual dalam konfigurasi server dan tidak tersedia untuk IPv6 menurut kralyk .

Inilah solusi menggunakan pernyataan ternary , menjaga kode minimal:

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

Ini adalah cara terkecil dan termudah untuk melakukan ini, dengan asumsi server web seseorang menggunakan port standar 443 untuk HTTPS .

Metode lintas platform favorit saya untuk menemukan URL saat ini adalah:

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

Cukup gunakan:

$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;
}

Catatan: Saya baru saja memperbarui kode Timo Huovinen , jadi Anda tidak akan mendapatkan parameter GET di URL. URL ini polos dan menghapus hal-hal seperti?hi=i&am=a&get .

Contoh:

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

akan ditampilkan sebagai:

http://www.example.com/index

Ini baik-baik saja kecuali Anda menggunakan parade GET untuk mendefinisikan beberapa konten tertentu, dalam hal ini Anda harus menggunakan kodenya! :-)

Hapus kode, berfungsi di semua server web (Apache, nginx, IIS, ...):

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

Ini solusi saya - kode diinspirasi oleh Tracy Debugger . Itu diubah untuk mendukung port server yang berbeda. Anda bisa mendapatkan URL lengkap saat ini termasuk $_SERVER['REQUEST_URI']atau hanya URL server dasar. Periksa fungsi saya:

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);
    }
}

Berikut ini adalah kode tes:

// 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/

HTTP_HOST dan REQUEST_URI harus dalam tanda kutip, jika tidak ada kesalahan dalam PHP 7.2

Menggunakan:

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

Jika Anda ingin mendukung HTTP dan HTTPS:

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

Teknik yang sama dengan jawaban yang diterima, tetapi dengan dukungan HTTPS , dan lebih mudah dibaca:

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

Saya telah membuat fungsi ini untuk menangani 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;
     }
 ?>

Gunakan lapisan satu ini untuk menemukan URL folder induk (jika Anda tidak memiliki akses ke http_build_url () yang disertakan bersama pecl_http):

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

Ini cukup mudah dilakukan dengan variabel lingkungan Apache Anda. Ini hanya berfungsi dengan Apache 2, yang saya anggap Anda gunakan.

Cukup gunakan kode PHP berikut:

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

Coba ini:

print_r($_SERVER);

$_SERVERadalah array yang berisi informasi seperti header, jalur, dan lokasi skrip. Entri dalam array ini dibuat oleh server web. Tidak ada jaminan bahwa setiap server web akan menyediakan semua ini; server dapat menghilangkan beberapa, atau menyediakan yang lain yang tidak tercantum di sini. Yang mengatakan, sejumlah besar variabel-variabel ini dicatat dalam spesifikasi »CGI / 1.1, sehingga Anda harus dapat mengharapkan mereka.

$HTTP_SERVER_VARSberisi informasi awal yang sama, tetapi bukan superglobal. (Perhatikan bahwa $HTTP_SERVER_VARSdan $_SERVERmerupakan variabel yang berbeda dan PHP menanganinya seperti itu)

Anda dapat menggunakan http_build_url tanpa argumen untuk mendapatkan URL lengkap dari halaman saat ini:

$url = http_build_url();

Saya telah membuat kelas ini untuk menangani URI saya

Tentu saja Anda harus menyesuaikannya dengan kebutuhan dan sistem Anda !?

// Get the URI class

var_dump(_URI::Extract());
echo '</pre>';
// Output extracted segments individually

'); 

Itu masih perlu disempurnakan tetapi itu adalah solusi terbaik untuk sistem URI terpusat: D

Ini adalah solusi untuk masalah Anda:

//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;

Saya menggunakan pernyataan ini.

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

Saya harap ini akan membantu Anda.

    public static function getCurrentUrl($withQuery = true)
    {
        $protocol = (!empty($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off')
        or (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && strtolower($_SERVER['HTTP_X_FORWARDED_PROTO']) === 'https')
        or (!empty($_SERVER['HTTP_FRONT_END_HTTPS']) && strtolower($_SERVER['HTTP_FRONT_END_HTTPS']) !== 'off')
        or (isset($_SERVER['SERVER_PORT']) && intval($_SERVER['SERVER_PORT']) === 443) ? 'https' : 'http';

        return $withQuery ? $uri : str_replace('?' . $_SERVER['QUERY_STRING'], '', $uri);
    }

Saya telah menggunakan kode di bawah ini, dan berfungsi dengan baik untuk saya, untuk kedua kasus, HTTP dan 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

$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.

Berikut adalah dasar dari versi yang lebih aman dari jawaban yang diterima, menggunakan fungsi filter_input PHP , yang juga menggantikan kekurangan potensial $_SERVER['REQUEST_URI']:

$protocol_https = filter_input(INPUT_SERVER, 'HTTPS', FILTER_SANITIZE_STRING);
$host = filter_input(INPUT_SERVER, 'HTTP_HOST', FILTER_SANITIZE_URL);
$request_uri = filter_input(INPUT_SERVER, 'REQUEST_URI', FILTER_SANITIZE_URL);
if(strlen($request_uri) == 0)
{
    $request_uri = filter_input(INPUT_SERVER, 'SCRIPT_NAME', FILTER_SANITIZE_URL);
    $query_string = filter_input(INPUT_SERVER, 'QUERY_STRING', FILTER_SANITIZE_URL);
    if($query_string)
    {
        $request_uri .= '?' . $query_string;
    }
}
$full_url = ($protocol_https ? 'https' : 'http') . '://' . $host . $request_uri;

Anda dapat menggunakan beberapa filter berbeda untuk menyesuaikannya sesuai keinginan Anda.

Anda dapat menggunakan HTTP_ORIGINseperti yang diilustrasikan dalam cuplikan di bawah ini:

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

Penggunaan yang sangat sederhana:

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;
}

Saya pikir metode ini bagus .. coba saja

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/');
}

Ini berfungsi untuk HTTP dan HTTPS.

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

Keluarkan sesuatu seperti ini.

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

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