Access the resources in Apache to download their files directly

The access PHP file will prompt to download its files, for what reason? Http.conf about PHP is configured as follows:

AddType application/x-httpd-php. php
AddType application/x-httpd-php. html
AddType application/x-httpd-php. htm

LoadModule php5_module "D:/php/php5apache2_2.dll"
Phpinidir "D:/php/php.ini"

Reply to discussion (solution)

Check if the Php5apache2_2.dll file is present under d:/php?

Phpinidir "D:/php/php.ini"
Change into
Phpinidir "d:/php/"
