完全なURLを PHP

完全なURLを取得するには、このコードを使用します。

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

問題は、私の.htaccessでいくつかのマスクを使用しているため、URLに表示されるものがファイルの実際のパスとは限らないことです。

必要なのは、URL、そのURLに書かれているもの、それ以上でもそれ以下でも - 完全なURLを取得することです。

サーバ上のファイルの実際のパスではなく、Webブラウザのナビゲーションバーに表示される方法を取得する必要があります。

$_SERVER['REQUEST_URI']を見てください。

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

（二重引用符で囲まれた文字列の構文は 完全に正しい です。）

HTTPとHTTPSの両方をサポートしたい場合は、

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

編集者のメモ： このコードを使うことには セキュリティ上の影響 があります。クライアントはHTTP_HostとREQUEST_URIを任意の値に設定できます。

ウェブページ上のリンクを出力するためのショートバージョン

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

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

//example.com/path/形式 の問題とEdgeのケースについての詳細がここにあります。

URLの構造

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

太字の部分は関数に含まれません

ノート：

  • この関数は、完全なURLからのusername:passwordやフラグメント（ハッシュ）を含みません。
  • HTTPのデフォルトポート80およびHTTPSのポート443は表示されません。
  • Httpおよびhttpsスキームでのみテストされています。
  • #fragment_idは、クライアント（ブラウザ）によってサーバーに送信されず、完全なURLに追加されません。
  • $_GETは、foo=bar2のようなURLに対しては/example?foo=bar1&foo=bar2のみを含みます。
  • CMSや環境によっては$_SERVER['REQUEST_URI']を書き換えて/example?foo=bar2のようなURLに/example?foo=bar1&foo=bar2を返すでしょう。この場合は$_SERVER['QUERY_STRING']を使用してください。
  • _ uri _ = URL + URNであることを忘れないでください、しかし一般的な使用のために、URLは現在URIとURLの両方を意味します。
  • プロキシやバランサを使用する予定がない場合はHTTP_X_FORWARDED_Hostを削除する必要があります。
  • spec は、デフォルトの番号でない限り、Hostヘッダーにポート番号を含める必要があることを示しています。

クライアント（ブラウザ）制御変数：

  • $_SERVER['REQUEST_URI']。サポートされていない文字は送信される前にブラウザによってエンコードされます。
  • $_SERVER['HTTP_Host']そしてPHPマニュアルのコメントによると常に利用可能というわけではありません： http://php.net/manual/en/reserved.variables.php
  • $_SERVER['HTTP_X_FORWARDED_Host']はバランサによって設定され、PHPマニュアルの$_SERVER変数のリストには記載されていません。

サーバー制御変数

  • $_SERVER['HTTPS']。クライアントはこれを使用することを選択しますが、サーバーは空または "on"のいずれかの実際の値を返します。
  • $_SERVER['SERVER_PORT']。サーバーは許可された番号のみをポートとして受け入れます。
  • $_SERVER['SERVER_PROTOCOL']。サーバーは特定のプロトコルのみを受け入れます。
  • $_SERVER['SERVER_NAME']。これはサーバー設定で手動で設定され、 kralyk に従ってIPv6では使用できません。

これは 三項ステートメント を使った解決策で、コードを最小限に抑えます。

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

自分のWebサーバーが _ https _ に標準ポート443を使用していると仮定すると、これがこれを行うための最小かつ最も簡単な方法です。

現在のURLを見つけるための私のお気に入りのクロスプラットフォームの方法は次のとおりです。

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

単に使用する：

$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;
}

注意：私は "Timo Huovinen"のコードを更新したばかりなので、URLの情報を取得することはありません。このURLはわかりやすく、 "？hi = i＆am = a＆get"のようなものを削除します。

例：

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

次のように表示されます。

http://www.website.com/index

特定のコンテンツを定義するためにGetを使用しない限り、次に彼のコードを使用してください。 :-)

明確なコード、すべてのWebサーバー（Apache、nginx、IISなど）で機能します。

$url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' ? 'https' : 'http') . '://' . $_SERVER['HTTP_Host'] . $_SERVER['REQUEST_URI'];
15

これが私の解決策です - コードは Tracy Debuggerに触発されています 。異なるサーバーポートをサポートするために変更されました。 $_SERVER['REQUEST_URI']を含む現在の完全なURL、または単に基本的なサーバーURLを取得できます。私の機能を確認してください。

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);
    }
}

これがテストコードです。

// 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/

私はURLを処理するためにこの関数を作りました：

 <?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;
     }
 ?>

Web-Developer-Nil

このワンライナーを使用して、親フォルダーのURLを見つけます（pecl_httpに付随するhttp_build_url（）にアクセスできない場合）。

$url = (isset($_SERVER['HTTPS']) ? 'https://' : 'http://').$_SERVER['SERVER_NAME'].str_replace($_SERVER['DOCUMENT_ROOT'], '', dirname(dirname(__FILE__)));
7
Ralph Rezende Larsen

一般的な回答と同じ手法ですが、 _ https _ supportを使用し、読みやすくします。

$current_url = sprintf(
    '%s://%s/%s',
    isset($_SERVER['HTTPS']) ? 'https' : 'http',
    $_SERVER['HTTP_Host'],
    $_SERVER['REQUEST_URI']
);
7
Jonathon Hill

HTTP_HostとREQUEST_URIは引用符で囲む必要があります。それ以外の場合、PHP 7.2にエラーがスローされます。

つかいます：

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

HTTPとHTTPSの両方をサポートしたい場合は、

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

Kai Noack

これはあなたのApache環境変数を使ってするのはとても簡単です。これはApache 2でしか動作しません。あなたが使っていると思います。

次のPHPコードを使うだけです。

<?php
    $request_url = Apache_getenv("HTTP_Host") . Apache_getenv("REQUEST_URI");
    echo $request_url;
?>

これを試して：

print_r($_SERVER);

$_SERVERは、ヘッダー、パス、スクリプトの場所などの情報を含む配列です。この配列のエントリはWebサーバーによって作成されます。すべてのWebサーバーがこれらのいずれかを提供するという保証はありません。サーバはいくつかを省略するか、またはここに記載されていない他のものを提供するかもしれません。とはいえ、»CGI/1.1仕様ではこれらの変数の多くが占められているので、それらを期待できるはずです。

$HTTP_SERVER_VARSは同じ初期情報を含みますが、スーパーグローバルではありません。 （$HTTP_SERVER_VARSと$_SERVERは異なる変数であり、PHPはそれらをそのように扱います。）

現在のページの完全な _ url _ を取得するには、 http_build_url を引数なしで使用します。

$url = http_build_url();

Luke Mlsna

これはあなたの問題に対する解決策です：

//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;

私はこの文を使いました。

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

これがお役に立てば幸いです。

私は以下のコードを使用しました、そしてそれは私のためにうまく動いています、HTTPとHTTPSの両方の場合のために。

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();

これは、PHPの filter_input 関数を使用して、受け入れられた回答のより安全なバージョンの基礎であり、$_SERVER['REQUEST_URI']の潜在的な不足も補います。

$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;

いくつかの異なる filters を使用して、好みに合わせて調整できます。

非常に簡単な使い方

function current_url() {

    $current_url .= ( $_SERVER["SERVER_PORT"] != 80 ) ? ":".$_SERVER["SERVER_PORT"] : "";
    $current_url .= $_SERVER["REQUEST_URI"];

    return $current_url;

以下のスニペットに示すように、HTTP_Originを使用できます。

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

これはHTTPとHTTPSの両方で機能します。

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

このようなものを出力してください。

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

    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/');
