PHP Installation problem( with apache ) - help

hello, I've Apache 2.0.35 up and running. Installed PHP 4.2.1( for W2k ). I've some basic questions, can someone help me. I followed the instructions on install.txt but it doesn't seem to work. The only change I did in php.ini is including the extension_dir where I had installed PHP. Q : Do I need to copy this file to %SYSTEMROOT%( winnt/system32 ) or leave it in PHP's home directory ? On httpd.conf, Q : Do I need give the directory structure for "ScriptAlias" or not ? I added the entry - AddType application/x-httpd-php .php .phtml Q : I guess I need this, correct ? I also added Action application/x-httpd-php "F:/Program Files/php-4.2.1-Win32/php.exe" Q : Is this required ? Basic question of all, Q : while I give the directory entries, is it \ or / ? All help are really appreciated. Thanks. - shanky.
