New class Net_Geo

Hi. I've knocked up a class which is PEAR compatible called Net_Geo. This is a basic port of existing Java and Perl classes from caida.org. Net_Geo obtains geographical information based on IP address, host name or Autonomous System (AS) number. From this input, various information is returned including latitude and longitude ranging in granularity from Country to City depending on what's in the NetGeo database. You can check it out at http://inetix.com.au/php/test_netgeo.php I've found that even though you can feed in domain names, the NetGeo server does not always return a positive result whereas an IP number always works correctly so the test form converts to an IP before querying. I've also included a link to Map Quest for fun. Ouput formatted using Frederic's class Var_Dump class :) The caching is rather simple so any advice there would be appreciated. IIRC last time I tried the Cache/Function.php I could not use it inside a class. I'd love to see it go into PEAR is possible. Cheers, Graeme
