php is not found by apache

["Jack Godkin" <davidgj@xxxxxxxxxxxxxx>]

php is not found by apache, i have installed mysql,apache, and php in an xp environment both mysql and apache work fine but apache and windows do not seem to recognise the php extension. i have made the following changes to php.ini

redirected the extension directory from  extension_dir ="./" to the extension_dir where php can be found. I also enabled the extension=mysql

i transfered the libmysql.dll to C:\WINDOWS\system32\

in apachie the following was added by php installation wizerd :

#</VirtualHost>

#BEGIN PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL
PHPIniDir "C:\Program Files\PHP\"
LoadModule php5_module "C:\Program Files\PHP\php5apache2.dll"
#END PHP INSTALLER EDITS - REMOVE ONLY ON UNINSTALL

where did i go wrong ???

ps i also uninstalled and re-installed mysql,apache and php several times.
