我正在使用此代码，但无法下载excel和doc文件。

    if ($fileName) {
        $file = realpath ( "uploads/user_img" ) . "\\" . $fileName;
        // check file exists    
        if (file_exists ( $file )) {
            // get file content
            $data = file_get_contents ( $file );
            //force download
            force_download ( $fileName, $data );
        } else {
            // Redirect to base url
            redirect ( base_url () );
        }
    }
}

请使用以下代码：-

public function download_document($fileName=null){
    $this->load->helper('download');
    if ($fileName) {
        $file = "uploads/user_img/" . $fileName;
        // check file exists    
        if (file_exists ( $file )) {

            //force download
            force_download ( $file, NULL );
        } else {
            // Redirect to base url
            redirect ( base_url () );
        }
    }
}
