phpZipLocator needs a database with a table called zipData containing data for
ZipCodes to work properly

You can grab a zip file with the necesary data and table structure from here (389Kb)

Place the contents of the somewhere in your web document tree

Edit the file to have the proper details of the database where you
have the zipData table (you should ensure that this file is not seen from the browser)

Try accessing the ziptest.php file - you will get the following output if everything is right
The distance between 12345 and 23456 is 433.1607605336 Miles
There are 107 Zip codes within 20 Miles of 12345

See comments in phpZipLocator.php for the methods
See ziptest.php for sample usage.
See for a nice article on
distance calculation and try and figure out (im)precise phpZipLocator is ;-)
