から抽出した値に基づいて、最も一般的に使用されるパスを定数として定義するブートストラップ ファイルを使用してカスタム PHP プロジェクトを開始することをお勧めします$_SERVER
。プロジェクトまたはプロジェクトの一部を別のサーバーまたはサーバー上の別のディレクトリに移行するのが非常に簡単になります。
これは私のルートパスを定義する方法です:
define("LOCAL_PATH_ROOT", $_SERVER["DOCUMENT_ROOT"]);
define("HTTP_PATH_ROOT", isset($_SERVER["HTTP_HOST"]) ? $_SERVER["HTTP_HOST"] : (isset($_SERVER["SERVER_NAME"]) ? $_SERVER["SERVER_NAME"] : '_UNKNOWN_'));
パスLOCAL_PATH_ROOT
はドキュメント ルートです。パスHTTP_PATH_ROOT
は、HTTP 経由で同じパスにアクセスする場合と同等です。
その時点で、ローカル パスを HTTP パスに変換するには、次のコードを使用します。
str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, $my_path)
Windows ベースのサーバーとの互換性を確保したい場合は、ディレクトリ区切り記号を URL 区切り記号に置き換える必要があります。
str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, str_replace(DIRECTORY_SEPARATOR, '/', $my_path))

上記のコードを独自のプロジェクトに追加すると、この時点ですべてのユーザー定数が出力されます (これを行うとget_defined_constants(true)
、次のような結果が得られるはずです。
