I am working on displaying list of timezones by country name.
As answered here: Country to timezones in PHP/Zend Framework
I am thinking to call DateTimeZone::listIdentifiers(DateTimeZone::PER_COUNTRY, 'US') to list all timezones by country.
Is there any easy way to get list of ISO 3166-1 compatible country codes and their corresponding names in PHP(PHP 5.3)?
check out the most extensive and up-to-date list I could find:
http earth-info.nima.mil/gns/html/gazetteers2.html (old link see below)
they offer an xls download which contains the following columns:
FIPS 10-4 ISO 3166 digraph ISO 3166 trigraph ISO 3166 numeric TLD IOC SOVEREIGNTY
(check out the 4th sheet in the xls file)
Update 2016: the link is dead, try this: http://geonames.nga.mil/gns/html/
