PHP mandatory download problems

PHP mandatory download question & lt ;? Php $ file_dir = 'd:/file/'Your folder file_name}'xxx.zip '; $ file = fopen ($ file_dir. $ file_name, & quot; r & quot;); & nbsp; header (& quot; Content-Type: PHP mandatory download problem
$ File_dir = 'd:/file /';
$ File_name = 'XXX.zip ';
$ File = fopen ($ file_dir. $ file_name, "r ");
Header ("Content-Type: application/force-download ");
Header ("Accept-Ranges: bytes ");
Header ("Accept-Length:". filesize ($ file_dir. $ file_name ));
Header ("Content-Disposition: attachment; filename =". $ file_name );
// Output file content
Echo fread ($ file, filesize ($ file_dir. $ file_name ));
Fclose ($ file );
Exit;

Why did I read this file instead of directly downloading it when I run it like this ??

------ Solution --------------------
You 'd better not use fread ($ file, filesize ($ file_dir. $ file_name ));
You put
Echo fread ($ file, filesize ($ file_dir. $ file_name ));
Fclose ($ file );
Change
Readfile ($ file_dir. $ file_name );
Try
It is better to add the following two sentences
Header ("Cache-Control: must-revalidate, post-check = 0, pre-check = 0 ");
Header ("Pragma: no-cache ");
This should solve your problem.
