I am very much sure that the error is not by adding the line LoadModule php5_module "c:/php/php5apache2.dll". If you are using Apache 2.X, we need to add “c:/php/php4apache2.dll" instead of "c:/php/php4apache.dll".
U need to add more one line in the "http.conf� file
Simply search for the line in the file that begins with a "DirectoryIndex" and add "index.php" to the list of files on that line.
For Eg: change it to DirectoryIndex index.php index.html
The next time you access "localhost" or "localhost/directory/" without a filename, Apache will deliver "index.php" if available, or "index.html" if "index.php" is not available.
Then test for PHP
Create a PHP file with the following line:
<?phpinfo()?>
Save the file with the extension php(Eg:testphp.php) and save the file in your Apache htdocs directory(i.e c:\program files\apache group\apache\htdocs
access the file you just created by typing
http://localhost/testphp..phpinto in your browser.
U shd able to see all the information about your PHP setup.
I hope i have answered ur question...
Good luck then...
