Answer 1

$textcyr="Тест на кирилице";
$textlat="Test na kirilitse!";
$cyr  = array('а','б','в','г','д','е','ё','ж','з','и','й','к','л','м','н','о','п','р','с','т','у', 
            'ф','х','ц','ч','ш','щ','ъ', 'ы','ь', 'э', 'ю','я','А','Б','В','Г','Д','Е','Ж','З','И','Й','К','Л','М','Н','О','П','Р','С','Т','У',
            'Ф','Х','Ц','Ч','Ш','Щ','Ъ', 'Ы','Ь', 'Э', 'Ю','Я' );
$lat = array( 'a','b','v','g','d','e','io','zh','z','i','y','k','l','m','n','o','p','r','s','t','u',
            'f' ,'h' ,'ts' ,'ch','sh' ,'sht' ,'a', 'i', 'y', 'e' ,'yu' ,'ya','A','B','V','G','D','E','Zh',

            'F' ,'H' ,'Ts' ,'Ch','Sh' ,'Sht' ,'A' ,'Y' ,'Yu' ,'Ya' );

$textcyr = str_replace($cyr, $lat, $textcyr);
$textlat = str_replace($lat, $cyr, $textlat);
echo("$textcyr $textlat");

missing ё, э, ы (Э, Ы, Ё) letters

Answer 2

This is my version of transliteration table for russian alphabet. It's unofficial but based on technical standards GOST 7.79-2000 and GOST 16876-71. Multi-characters go first.

public static function transliterate($textcyr = null, $textlat = null) {
    $cyr = array(
        'ё',  'ж',  'х',  'ц',  'ч',  'щ',   'ш',  'ъ',  'э',  'ю',  'я',  'а', 'б', 'в', 'г', 'д', 'е', 'з', 'и', 'й', 'к', 'л', 'м', 'н', 'о', 'п', 'р', 'с', 'т', 'у', 'ф', 'ь',
        'Ё',  'Ж',  'Х',  'Ц',  'Ч',  'Щ',   'Ш',  'Ъ',  'Э',  'Ю',  'Я',  'А', 'Б', 'В', 'Г', 'Д', 'Е', 'З', 'И', 'Й', 'К', 'Л', 'М', 'Н', 'О', 'П', 'Р', 'С', 'Т', 'У', 'Ф', 'Ь');
    $lat = array(
        'yo', 'zh', 'kh', 'ts', 'ch', 'shh', 'sh', '``', 'eh', 'yu', 'ya', 'a', 'b', 'v', 'g', 'd', 'e', 'z', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'r', 's', 't', 'u', 'f', '`',
        'Yo', 'Zh', 'Kh', 'Ts', 'Ch', 'Shh', 'Sh', '``', 'Eh', 'Yu', 'Ya', 'A', 'B', 'V', 'G', 'D', 'E', 'Z', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'R', 'S', 'T', 'U', 'F', '`');
    if($textcyr)
        return str_replace($cyr, $lat, $textcyr);
    else if($textlat)
        return str_replace($lat, $cyr, $textlat);
    else
        return null;
}

Answer 3

Since all above are incomplete, here is my version:

    $textcyr="Тест на кирилице";
    $textlat="Test na kirilitse!";
         $cyr  = array('а','б','в','г','д','е','ё','ж','з','и','й','к','л','м','н','о','п','р','с','т','у', 
            'ф','х','ц','ч','ш','щ','ъ', 'ы','ь', 'э', 'ю','я',
            'А','Б','В','Г','Д','Е','Ё','Ж','З','И','Й','К','Л','М','Н','О','П','Р','С','Т','У',
            'Ф','Х','Ц','Ч','Ш','Щ','Ъ', 'Ы','Ь', 'Э', 'Ю','Я' );
$lat = array( 'a','b','v','g','d','e','e','zh','z','i','y','k','l','m','n','o','p','r','s','t','u',
            'f' ,'h' ,'ts' ,'ch','sh' ,'sht' ,'i', 'y', 'y', 'e' ,'yu' ,'ya','A','B','V','G','D','E','E','Zh',
            'Z','I','Y','K','L','M','N','O','P','R','S','T','U',
            'F' ,'H' ,'Ts' ,'Ch','Sh' ,'Sht' ,'I' ,'Y' ,'Y', 'E', 'Yu' ,'Ya' );

    $textcyr = str_replace($cyr, $lat, $textcyr);
    $textlat = str_replace($lat, $cyr, $textlat);
    echo("$textcyr $textlat");

I prefered ё = e, ъ = i, ы = y and э = e because I am using that way.

Answer 4

You should try iconv() with the //TRANSLIT option.

$trstr = iconv(<your encoding here>, "ISO-8859-1//TRANSLIT", $src_str)

Answer 5

This one worked best for me. Code is from this page

function ru2lat($str)
{
    $tr = array(
    "А"=>"a", "Б"=>"b", "В"=>"v", "Г"=>"g", "Д"=>"d",
    "Е"=>"e", "Ё"=>"yo", "Ж"=>"zh", "З"=>"z", "И"=>"i", 
    "Й"=>"j", "К"=>"k", "Л"=>"l", "М"=>"m", "Н"=>"n", 
    "О"=>"o", "П"=>"p", "Р"=>"r", "С"=>"s", "Т"=>"t", 
    "У"=>"u", "Ф"=>"f", "Х"=>"kh", "Ц"=>"ts", "Ч"=>"ch", 
    "Ш"=>"sh", "Щ"=>"sch", "Ъ"=>"", "Ы"=>"y", "Ь"=>"", 
    "Э"=>"e", "Ю"=>"yu", "Я"=>"ya", "а"=>"a", "б"=>"b", 
    "в"=>"v", "г"=>"g", "д"=>"d", "е"=>"e", "ё"=>"yo", 
    "ж"=>"zh", "з"=>"z", "и"=>"i", "й"=>"j", "к"=>"k", 
    "л"=>"l", "м"=>"m", "н"=>"n", "о"=>"o", "п"=>"p", 
    "р"=>"r", "с"=>"s", "т"=>"t", "у"=>"u", "ф"=>"f", 
    "х"=>"kh", "ц"=>"ts", "ч"=>"ch", "ш"=>"sh", "щ"=>"sch", 
    "ъ"=>"", "ы"=>"y", "ь"=>"", "э"=>"e", "ю"=>"yu", 
    "я"=>"ya", " "=>"-", "."=>"", ","=>"", "/"=>"-",  
    ":"=>"", ";"=>"","—"=>"", "–"=>"-"
    );
return strtr($str,$tr);
}

Hope this helps someone.

Respecting the Yandex transliteration rules (http://www.translityandex.ru/) and converting the upper case:

function translit_russian_filenames( $filename ) {
    $info = pathinfo( $filename );
    $ext  = empty( $info['extension'] ) ? '' : '.' . $info['extension'];
    $name = basename( $filename, $ext );
     $cyr = array(
    'а', 'б', 'в', 'г', 'д', 'е', 'ё', 'ж', 'з', 'и', 'й', 'к', 'л', 'м', 'н', 'о', 'п', 'р', 'с', 'т', 'у', 'ф', 'х', 'ц', 'ч', 'ш', 'щ', 'ъ', 'ы', 'ь', 'э', 'ю', 'я',
    'А', 'Б', 'В', 'Г', 'Д', 'Е', 'Ё', 'Ж', 'З', 'И', 'Й', 'К', 'Л', 'М', 'Н', 'О', 'П', 'Р', 'С', 'Т', 'У', 'Ф', 'Х', 'Ц', 'Ч', 'Ш', 'Щ', 'Ъ', 'ы', 'Ь', 'Э', 'Ю', 'Я' );
    $lat = array(
    'a', 'b', 'v', 'g', 'd', 'e', 'yo', 'zh', 'z', 'i', 'y', 'k', 'l', 'm', 'n', 'o', 'p', 'r', 's', 't', 'u', 'f', 'h', 'c', 'ch', 'sh', 'shch', '', 'y', '', 'e', 'yu', 'ya',
    'a', 'b', 'v', 'g', 'd', 'e', 'yo', 'zh', 'z', 'i', 'y', 'k', 'l', 'm', 'n', 'o', 'p', 'r', 's', 't', 'u', 'f', 'h', 'c', 'ch', 'sh', 'shch', '', 'y', '', 'e', 'yu', 'ya');
    $name_translit = str_replace($cyr, $lat, $name);
    return $name_translit . $ext;
}
add_filter( 'sanitize_file_name', 'translit_russian_filenames', 10 );
