By default .php files are parsed as PHP4 on ec2Link.com Website Hosting servers.

All files extension in .php, .php3, and .php4 are handled by PHP4.
All files extension in .php5 are handled by PHP5.

If you prefer that all files be parsed as PHP5, please create or change the .htaccess file with the following line:

AddHandler fcgid-script .php

Upload this file into the root of your domain(e.g. httpdocs). The changes take effect immediately.
