= Distance Finder =
PHP script allowing users to find the air distance between cities. Uses information from Google if data not found in local database.
== License ==
Distance Finder by Klaus-Uwe Mitterer is licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License. To view a copy of this license, visit http://creativecommons.org/licenses/by-sa/3.0/.
Permissions beyond the scope of this license may be available at info@klaus-uwe.me.
== Installation ==
Change the following settings in bootstrap.php:
DB_HOST = The host on which your MySQL database is running. Usually localhost.
DB_NAME = The name of your MySQL database.
DB_USER = The user name for your MySQL database.
DB_PASSWORD = The corresponding password.
CSVFILE = The file you want to import to the database. Has to be in the following format: City name, Country code, State code, Population, Latitude, Longitude. Can be an empty file. Make sure this file exists in the same folder as the install.php
Then go to http://yoursite.com/[subdirectory]/install.php and follow the instructions. Depending on the size of the CSV file you are importing into the database, this might take a while.
When the installation has finished, you might want to remove or rename install.php.
== Troubleshooting ==
If you keep getting empty files when trying to download the distance list, make sure that the web server has permissions to write in the folder (e.g. chown www-data:www-data)
