私は を実行してCENTOS 6.3おりPHP 5.4.9、 を使用していPHP FTP commandsます。これを使用して、1 つのドメインから同じサーバー上の FTP アカウントに大きなファイルをアップロードしています。

私が気付いたのは、小さなファイルのアップロードでも、アップロードに時間がかかることです。約 10 ～ 15 秒です。彼らは最終的にアップロードします。同じスクリプトを使用して別のサーバーにアップロードすると、1 秒未満で高速にアップロードされます。

別のサーバーで同じ FTP 資格情報を使用でき、高速にアップロードされます。同じサーバー上の 1 つのドメインからの FTP が遅いのはなぜですか?

スクリプトで更新:

$ftp_server = "HOST NAME";
$ftp_user_name = "USERNAME";
$ftp_user_pass = "PASSWORD";
$ftp_folder = "/FTP DIRECTORY";
$path = "/testing/";
$file_name = $_FILES["theFile"]["name"];
$source_file = $_FILES["theFile"]["tmp_name"];
$destination_file = $ftp_folder.$path.$file_name;
$destination_path = $ftp_folder.$path;


function uploadFTP($ftp_server, $ftp_user_name, $ftp_user_pass, $source_file, $destination_file, $destination_path) {
    $conn_id = @ftp_connect($ftp_server); // set up basic connection
    $login_result = @ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // login with username and password
    if ((!$conn_id) || (!$login_result)) { // check connection 
        return false;
    } else {
        $check = @ftp_chdir($conn_id, $destination_path); //check to see if folder is there
        if ($check) { 
            $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // upload the file
            if (!$upload) { // check upload status
                return false;
            } else {
                return true;
            }
        } else { 
            $check = @ftp_mkdir($conn_id, $destination_path); //make new folder
            if ($check) {
                $upload = @ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); // upload the file
                if (!$upload) { // check upload status
                    return false;
                } else {
                    return true;
                }
            } else {
                return false;
            }
        }

    }
    @ftp_close($conn_id); //close ftp
}

それらが同じサーバー上にある場合は、ファイルを送信するのではなく、ファイルをコピーしてから元に戻してください。ポート 21 (FTP) がアウトバウンド接続とインバウンド接続で詰まっていると思います。
