Преобразовать название страны в код страны Сокращения php

Сам PHP не знает этих значений. Вы должны создать свой собственный код:

Способ 1:

Создайте такой массив, как:

$COUNTRY = array( "Australia" => "AU", "Germany" => "GER" ... ); 

После этого просто используйте предварительно сохраненные значения:

 echo $COUNTRY['Australia']; 

Способ 2 (предлагается):

Сохраните значения в БД:

 +-----------+------+ | Country | Code | +-----------+------+ | Australia | AU | | Germany | GER | ... +-----------+------+ 

И Доступ с простым запросом:

 SELECT Code FROM country_db WHERE Country = 'Australia';
