mysqldump via php

I would like to do a backup of an entire MySQL database via php. My
thought was to use mysqldump, write the data to a file and save the
file. However...

$query="mysqldump $dbase";
$result=mysql_query($query) or die(mysql_error());

....immediately results in an "error in your SQL syntax near mysqldump
[database name]".

The reason I want to do a MySQL back up via php is that I have a web
application in which the user can archive a project, which involves
moving a lot data from one set of tables to another set of tables. The
user can also delete a project, which removes lots of data from the DB
altogether. Although there are lots of "Are you sure you really want to
do this?" messages the user must click upon, I am sure I will eventually
get a user telling me she accidentally archived/deleted stuff and can I
help.

So, my thought was to do a incorporate a mysqldump in the
archiving/delete page. That way there would be a snapshot of the
pre-action db, making it easy to put things right.

Can you help with my query - or by suggesting an alternative solution?

Thanks,

Jeffrey

mysqldump is a .exe, and therefore it will not work within mysql_query();

You may be able to use mysqldump from PHP using the system function

RE: mysqldump via php

You could use exec() within PHP!

Re: mysqldump via php

Thanks all for the help!

exec() seems the best option.
