Apache won't restart, says it cannot load php5apache2_2.dll

Hi, can anyone help me? I’m following Kevin yank’s book installing MySQL, Apache and PHP on windows 7, all working till right at the end. Apache fails to re-start once i add these lines to httpd.conf:
LoadModule php5_module “C:/PHP/php5apache2_2.dll”
AddType application/x-httpd-php .php
PHPIniDir “C:/PHP”

it says it cannot load php5apache2_2.dll - when i looked this dll wasn’t there, but having downloaded it and put it in the appropriate folder I still get the same error message. Apache is version 2.2.15 and PHP is 5.3.2

thanks!
Nancy

ok I fixed the problem - I’ve now installed the VC6 thread-safe version of PHP and not the VC9 non-thread version. Can’t see in Kevin’s book where it says which to choose, though. Am looking at the most recent PDF free 4-chapter download because my hard copy of the book’s a bit out of date.
Seen others having the same problem so I thought I’d mention it…
