Download txt file from server to client with PHP

  • 772

Hello everyone I am processing a txt file on the server using PHP

$file = fopen("archivos/llaves/keyusuario.txt", "w");
fwrite($file, 'Tu llave de usuario es: 651651651651651651');
fclose($file);

I am saving the txt in a folder on the server, now I want that txt to be downloaded in the client browser, I have tried the following using the absolute path:

   $rutaArchivo = __DIR__."archivos/llaves/keyusuario.txt";
    $NombreArchivo = basename($rutaArchivo);
    header('Content-Type: application/octet-stream');
    header("Content-Transfer-Encoding: Binary");
    header("Content-disposition: attachment; filename=$nombreArchivo");
    # Leer el archivo y sacarlo al navegador
    readfile($rutaArchivo);

However, at the end of the processing the file is successfully generated in the server folder, but the download is not carried out, I would greatly appreciate your help, thank you very much in advance

    Try this:

    $rutaArchivo = __DIR__."/archivos/llaves/keyusuario.txt";
$archivo = file_get_contents($rutaArchivo);
$NombreArchivo = basename($rutaArchivo);

header('Content-Description: File Transfer');
header('Content-Disposition: attachment; filename='.$NombreArchivo);
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($archivo));
header("Content-Type: text/plain");
readfile($rutaArchivo);

    Explanation:

    • You were trying to download a text file as if it were binary and you had the wrong headers
    • Here you had a typo:
    header("Content-disposition: attachment; filename=$nombreArchivo")

    because $FileName does not exist, it was $FileName
