Question : username php script - how to point it to an excel list

i have the following php username that i am using

http://roshanbh.com.np/2008/04/check-username-available-ajax-php-jquery.html

it works good and i see the php script like this example.

the question is, instead of having to fill the names in the following php script,
can i save an excel page like the image attached and have the script look at that?

Answer : username php script - how to point it to an excel list

Another solution can be using vpn-filter:

access-list filter permit tcp 10.254.254.0 255.255.255.0 host 192.168.100.2 eq 80
access-list filter deny tcp 10.254.254.0 255.255.255.0 host 192.168.100.2
access-list filter permit ip any any

Assuming that u r using DfltGrpPolicy as the group-policy for remote-access:

group-policy DfltGrpPolicy attributes
vpn-filter filter

The advantage of using vpn-filter is that it will not even allow denied traffic to go to local network. Whereas, in the other method, only the reply from the local-network is denied. The local network will still be getting requests which is meant to be denied.
