Each time I view a php page on localhost, it downloads the page

Question

Hi,

I have altered the httpd.conf file good to my knowledge by adding index.php in the directory index,

LoadModule php5_module "d:/php/php5apache2_2.dll"
    AddType application/x-httpd-php .php
    PHPIniDir "d:/php"

But any .php file I load, it downloads it.

Any help would be appreciated.

Thanks Jean
