Probably 4.3.2 based on what Apache's telling you. Two other ways of getting the version number are via your package management system (rpm -qa | egrep -i php) and asking Apache directly:

What user and group does your webserver run as? Use something like:

$ ps -e -o euser,egroup,pid,ppid,args | egrep httpd
root     root      1064     1 /usr/sbin/httpd -f /etc/httpd/httpd.conf -D SSL -D STATUS
wwwrun   nogroup   1178  1064 /usr/sbin/fcgi- -f /etc/httpd/httpd.conf -D SSL -D STATUS
wwwrun   nogroup   1190  1064 /usr/sbin/httpd -f /etc/httpd/httpd.conf -D SSL -D STATUS
wwwrun   nogroup   1700  1064 /usr/sbin/httpd -f /etc/httpd/httpd.conf -D SSL -D STATUS

showing that this webserver runs as user wwwrun, group nogroup.

To fix, go to the root of the phpwiki directory and do

$ chown -R wwwrun:nogroup .

substituting in the user and group that your webserver runs as. You will
probably need to do this as root (via sudo, etc...)

The docs don't reflect the current code.

My guess is that you want to change database type in
./config/config.ini. This is not obvious.

  find . -type f -print | xargs egrep -i '\$DBParams\[.dbtype.\] = '

gives:

./lib/IniConfig.php:    $DBParams['dbtype'] = @$rs['DATABASE_TYPE'];
./lib/IniConfig.php:        $DBParams['dbtype'] = 'dba';
./wiki://$DBParams['dbtype'] = 'SQL';

and poking in ./lib/IniConfig.php gives a link to
./config/config-default.ini; poking in ./index.php gives a link to
./config/config.ini. Without a lot of rummaging, you wouldn't have found
this.

Look for a basic tutorial on PHP and read through your Apache
configuration file. Make a file consisting of the line '<?php phpinfo();
?>' and make sure it's readable by the webserver. If you can get that
file to display correctly (giving you way too much info about PHP), you
can put the phpwiki directory there and start using it (see above for
changing file ownership.)

I usually put the files outside the docroot and tell Apache where to
find them using the Alias and Directory directives but putting the
directory under the docroot should work as well.

Welcome to the learning curve! :)
