“In programming, a locale is a set of parameters that define
attributes for a user’s specific geographic location, including the
user’s language, country and any special variant preferences that

article continued with the PHP language as we explored how to make
your dates locale aware, using both the native datetime functions
as well as the I18N_DateTime class. Today, we’ll be covering PHP’s
two remaining I18N Libraries, the I18N_Number and I18N_Currency
