no modules or extensions

I have just reinstalled php5 5.2.8 for the umpteenth time on FreeBSD and 
cannot get session or mysql modules installed.
web page info.php shows the correct path to the extensions.ini file, 
reports the file was parsed and file locations etc. are all ok. But 
there is no session or mysql reference on the page.

php5 is an upgrade from 5.2.7 (which worked fine and showed all the 
extension on the info.php page and phpmyadmin worked fine and webmin 
accessed and worked with mysql.

Now, neither phpmyadmin nor webmin are correctly functional

phpmyadmin shows error - "Cannot load session extension. Check php 
configuration.

I even deinstalled and reinstalled php5-mysql and php5-session after 
deleting the session.so and mysql.so files from extensions.ini

And there are no LoadModules in for MySQL or session in apache22 2.11 
httpd.conf

Since upgrading apache22 and php5 apache22 no longer displays pages with 
php coding; it does disiplay the an index.php page that has only html 
coding but not if php-coded pages are loaded from the index.php page.

I am lost again. Please show me where I have gone wrong...
