#15 MySQL installation problems

[Anonymous]

I installed phpwiki-1.3.2 at:
http://www.zpub.com/php4/wiki/phpwiki-1.3.2/

it seems to work but when I edit pages I get the error
message:

Warning! DBA files are in the /tmp directory. Please
read the INSTALL file and move the DB file to a
permanent location or risk losing all the pages!

I am not sure where the /tmp directory currently is on
my server (it's hosted by www.phpwebhosting.com) - or
what I should replace the line
'directory' => "/tmp",
in the index.php file.

I also tried to install phpwiki to use MySQL at:
http://zpub.com/sf/history/index.php/

but get WikiFatalError - do I have to create initial
tables?

Is there some advantage to using MySQL with phpwiki?

thanks
