I am trying to create a one click backup database script so non-geek
office staff can do backups, but so far I can only output empty files -
the new file appears, but it is empty....

E.G.
$db_user = "root";
$db_password = "";
$db_database = "or";
$db_server = "localhost";
$backup_path = "C:\\xampp\\htdocs\\openreal\\admin\\backup\\";
$path_to_mysqldump = "C:\\xampp\\mysql\\bin\\";
$filename = "backup".date("YmdHis").".sql";

shell_exec ("mysqldump $db_database > $path_to_mysqldump.$filename
--user=$db_user --password=$db_password");

I have tried various forms of this syntax with no content output?

Don't think microsofts qdos supports stream redirections and I don't think you
want a dot as the first in the filename.

try

shell_exec ("mysqldump $db_database --result-file=$path_to_mysqldump$filename
--user=$db_user --password=$db_password");

Thanks for the reply - What is qdos?

I am trying to do this with php code, but don't really know what I'm
doing............
This is to run under an existing php program

...and IF that really is your password and/or directory tree, please
modify them!

'Quick and Dirty Operating System' (qdos) is what MS-Dos is.

OK - solved that. This works"-

$fish= "$path_to_mysqldump\\mysqldump.exe --u $db_user
--ignore-table=$db.$config $db > $filename ";
exec($fish);
