OK, I know this is a very common problem but I'm having problems installing Apache (2.2.6)/PHP (5.2.5)/MySQL (5.1.11) on Windows....

Despite performing all the usual configuration changes (editing conf.httd, php.ini adding the required .dll's) but PHP seems to be unable to *see* MySQL.

Running the phpinfo() function returns information about PHP etc but does not include information about MySQL.

Any ideas?
