module provides access to the ISO two-letter
codes for identifying languages, as defined in ISO 639. You can either
access the codes via the conversion routines (described below),
or via the two functions which return lists of all language codes or
all language names.
There are two conversion routines:
This function takes a two letter language code and returns a string which contains the name of the language identified. If the code is not a valid language code, as defined by ISO 639, then
undefwill be returned.
- $lang = code2language($code);
This function takes a language name and returns the corresponding two letter language code, if such exists. If the argument could not be identified as a language name, then
undefwill be returned.
- $code = language2code('French');
The case of the language name is not important. See the section KNOWN BUGS AND LIMITATIONS below.
There are two function which can be used to obtain a list of all language codes, or all language names:
Returns a list of all two-letter language codes. The codes are guaranteed to be all lower-case, and not in any particular order.
Returns a list of all language names for which there is a corresponding two-letter language code. The names are capitalised, and not returned in any particular order.
The following example illustrates use of the

KNOWN BUGS AND LIMITATIONS
In the current implementation, all data is read in when the module is loaded, and then held in memory. A lazy implementation would be more memory friendly.
Currently just supports the two letter language codes - there are also three-letter codes, and numbers. Would these be of any use to anyone?
ISO codes for identification of country (ISO 3166). Supports 2-letter, 3-letter, and numeric country codes.
ISO codes for identification of written scripts (ISO 15924).
ISO three letter codes for identification of currencies and funds (ISO 4217).
