Issues with PHP module in Windows

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
I am getting the following error "Syntax on the line number and the module cannot be loaded" when I am trying to load the PHP module in Apache 2.2 on windows OS.
I have tried the following option but it didn't 
worked.I still get the syntax error.The php dll is present in the dir but still it is not able to load and giving syntax error.

#LoadModule php4_module "c:/php/php4apache2.dll"
#LoadModule php4_module "c:\php\php4apache2.dll"
LoadModule php4_module modules/php4apache2.dll

Any help would be much appreciated.
Thanks and regards
Arnab
