You can use the Google Maps API for that   See the blog post below for more information   http   stuff nekhbet ro 2008 12 12 how-to-get-coordinates-for-a-given-address-using-php html

PHP has some nice built in functions for getting geographic location  Maybe have a look here  http   php net manual en ref geoip php  According to php manual   This extension requires the GeoIP C library version 1 4 0 or higher to be installed  You can grab the latest version from    http   www maxmind com app c and compile it yourself

There is no forumula  as street names and cities are essentially handed out randomly  The address needs to be looked up in a database  Alternatively  you can look up a zip code in a database for the region that the zip code is for   You didn t mention a country  so I m going to assume you just want addresses in the USA  There are numerous databases you can use  some free  some not   You can also use the Google Maps API to have them look up an address in their database for you  That is probably the easiest solution  but requires your application to have a working internet connection at all times
