configuring php and apache

hi all, i have installed php and apache on my home computer..i am running xp home edition. the problem is that the php and apache are not working together. what i have done so far: 1. configured the httpd.conf file by adding the following lines: ScriptAlias /php/ "c:/php/" AddType application/x-httpd-php .php .phtml Action application/x-httpd-php "/php/php.exe" 2.moved the php4ts.dll file to windows\system32....note i do not have a directory called winnt 3.configured the php.ini file(located in windows dir)so that: extension_dir = c:\windows\system32 //points to where i located the php4ts.dll file doc_root = c:\program files\apache group\apache\htdocs //points to the document root file. i will be storing my files in the htdocs dirrectory. what am i doing wrong
