Can I run PHP 5 applications?

Yes! By default php4 is used for all .php files however with a simple .htaccess file modification PHP5 can be used.

Simply create a .htaccess file in the folder where you want to run PHP 5 and include the following two lines of text:

# Use PHP5 as default
AddHandler application/x-httpd-php5 .php

Once you save this PHP5 will be used to process all .php files in this folder.
