Converts mailing addresses into a normalized format
The main purpose of this package is as the first layer of address normalization and standardization. Recommended use is to pre-parse/normalize an address and compare to an existing cache/record set using the hash functions.
A way to normalize US mailing addresses without the need for an external service. This is a port of the perl module Geo::StreetAddress::US originally written by Schuyler D. Erle.
This is a fork from khartnett/address-normalization -- kudos for the original work!
This is a very basic normalizer. It realistically only handles US-based addresses, and should not be considered dependable for strict address-to-address comparison. This normalizer does not verify the validity of the address! If you are dependent on accurate addresses, you need to be using some other means (3rd party service, most likely) to verify an address.
I forked and added features to this package because I needed a decent first-layer to pre-normalize addresses before sending them our standardization service. This helps us limit the number of calls and strict dependence on the service, but also lets us catch a few easy-to-match scenarios here and there, which is a better user experience.
Libpostal is probably the best of its class in this area. I decided not to use Libpostal because: (1) It requires a few Gbs of space, which is undesirable in my current environment, and (2) it's probably overkill, since I consider our 3rd party service to be authoritative in the matter anyway.

<?php use ZeroDaHero\Normalizer; $normalizer = new Normalizer(); $address = $normalizer->parse('204 southeast Smith Street Harrisburg, or 97446'); $address->toString(); // or (string) $address; /* string: "204 SE Smith St, Harrisburg, OR 97446" */ $address->toArray(); /* array: [ '204 SE Smith St', 'Harrisburg, OR 97446' ]
If you only need to make use of a consistent way of hashing (e.g. if you're starting with a dependable 5-part address, such as from a 3rd party service), you can build a
<?php use ZeroDaHero\SimpleAddress; $address = new SimpleAddress('1234 Main St NE', null, 'Minneapolis', 'MN', '55401'); $address->getHash(); // full hash minus zip $address->getFullHash(); // full hash including zip // or do it all with the factory method: SimpleAddress::hashFromParts('1234 Main St NE', null, 'Minneapolis', 'MN', '55401'); // CANNOT hash street, since the component parts don't exist $address->getStreetHash(); // throws exception
