Question

if($_POST['mode']=="save") {
$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/mcboeking/";
$path = $root.$path;
$file_path = $_POST['path'];
$file = $path.$file_path;

if(!file_exists($file)) {
    die('file not found');
} else {
    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header('Content-Type: application/force-download');
    header("Content-Disposition: attachment; filename=\"".basename($file)."\";" );
    header("Content-Length: ".filesize($file));
    readfile($file);}}

As soon as I download the file and open it I get an error message. When i try to open a .doc file I get the message: file structure is invalid.
And when i try to open a .jpg file: This file can not be opened. It may be corrupt or a file format that Preview does not recognize.

But when I download PDF files, they open without any problem.

Can someone help me?

P.s. i tried different headers including :
header(‘Content-Type: application/octet-stream’);

$fsize = filesize($yourFilePath); 
$allowed_ext = array (

  // archives
  'zip' => 'application/zip',

  // documents
  'pdf' => 'application/pdf',
  'doc' => 'application/msword',
  'xls' => 'application/vnd.ms-excel',
  'ppt' => 'application/vnd.ms-powerpoint',

);
$mtype = mime_content_type($file_path);
if ($mtype == '') {
    $mtype = "application/force-download";
}
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: $mtype");
header("Content-Disposition: attachment; filename=\"$asfname\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . $fsize);
//then ur rest code
