Where to get started

[never_rain]

This is my first time using GeoNames. I have gone through the
documentation but it seems difficult for me to understand where to get
started. I would request you guys to please help me out and suggest
some links or the steps as where to start the process.

Here is what I am trying to achieve using GeoNames.

1. I have a directory website created in MySql and PHP.
2. I would like my visitors to enter a zip code.
3. System should check if the code is valid, if so than it should
check if there is any office located within that zip code range and
also should check within the proximity of 5 KM range of that zip code
if there are offices available with other zip codes.
4. I assume I have to download the database and integrate it with my
database.
5. Than once I am adding an office location, I can use the zip code
from that available database.

Please correct me if I am wrong and what will be the best way to
achieve this task. Is there any Demo PHP code available for this ?

Thanks for your help.
