List of Language Codes in YAML or JSON? [closed]

Answer 1

This PHP function will convert the language code to the language name, using the Library of Congress data file:

function lang_code_to_name($code)
{
    // init
    $lines = array();
    $line_items = array();
    $language = '';
    $code = strtolower($code);

    // strip any possible sub-language
    $pos = strpos($code, '-');
    if ($pos) {$code = substr($code, 0, $pos);}

    // get code list from Library of Congress
    // format: five elements per line
    // ISO 639-2 Alpha-3 bibliographic code|ISO 639-2 Alpha-3 terminology code|ISO 639-1 Alpha-2 code|English language name(s)|French language name(s)
    $url = 'http://loc.gov/standards/iso639-2/ISO-639-2_utf-8.txt';
    $list = file_get_contents($url);

    if (!$list) {return $language;}

    // read the file
    $lines = explode("\n", $list);
    for ($i; $i < sizeof($lines); $i++)
    {
        $line_item = explode("|", $lines[$i]);
        if (($line_item[0] == $code) || ($line_item[1] == $code) || ($line_item[2] == $code))
        {
            $language = $line_item[3];
            break;
        }
    }

    // exit
    return $language;
}
