convert_cyr_string

He is improved function to decode win1251->UTF8
<?php
        function win2utf($s){ 
            $c209 = chr(209); $c208 = chr(208); $c129 = chr(129);
            for($i=0; $i<strlen($s); $i++)    { 
                $c=ord($s[$i]);
                if ($c>=192 and $c<=239) $t.=$c208.chr($c-48);
                elseif ($c>239) $t.=$c209.chr($c-112);
                elseif ($c==184) $t.=$c209.$c209;
                elseif ($c==168)    $t.=$c208.$c129;
                else $t.=$s[$i];
            } 
            return $t;
        }
?>

A better function to convert cp1251 string to utf8.
Works with russian and ukrainian text.

function unicod($str) {
    $conv=array();
    for($x=128;$x<=143;$x++) $conv[$x+112]=chr(209).chr($x);
    for($x=144;$x<=191;$x++) $conv[$x+48]=chr(208).chr($x);
    $conv[184]=chr(209).chr(145); #ё
    $conv[168]=chr(208).chr(129); #Ё
    $conv[179]=chr(209).chr(150); #і
    $conv[178]=chr(208).chr(134); #І
    $conv[191]=chr(209).chr(151); #ї
    $conv[175]=chr(208).chr(135); #ї
    $conv[186]=chr(209).chr(148); #є
    $conv[170]=chr(208).chr(132); #Є
    $conv[180]=chr(210).chr(145); #ґ
    $conv[165]=chr(210).chr(144); #Ґ
    $conv[184]=chr(209).chr(145); #Ґ
    $ar=str_split($str);
    foreach($ar as $b) if(isset($conv[ord($b)])) $nstr.=$conv[ord($b)]; else $nstr.=$b;
    return $nstr;
}

Transliteration could be done easier:

function transliterate($cyrstr)
    {
        $ru = array('A', 'a',

Sorry for my previous post. NOT array_reverce, array_flip is actual function. Correct function:

function Encode($str,$type=u)
{
    $conv=array();
    for($x=192;$x<=239;$x++)
        $conv[u][chr($x)]=chr(208).chr($x-48);
    for($x=240;$x<=255;$x++)
        $conv[u][chr($x)]=chr(209).chr($x-112);
    $conv[u][chr(168)]=chr(208).chr(129);
    $conv[u][chr(184)]=chr(209).chr(209);
    $conv[w]=array_flip($conv[u]);
    if($type=='w' || $type=='u')
        return strtr($str,$conv[$type]);
    else
        return $str;
}

Sorry for my English ;)

threed's function works great, but the replacement for the letter small io (ё) needs to be changed from 
<?php
if ($c==184) { $t.=chr(209).chr(209); continue; };
?>

to
<?php
if ($c==184) { $t.=chr(209).chr(145); continue; };
?>

so, the final working result should look like this:
<?php
function win3utf($s) {
   for($i=0, $m=strlen($s); $i<$m; $i++)    {
       $c=ord($s[$i]);
       if ($c<=127) {$t.=chr($c); continue; }
       if ($c>=192 && $c<=207) {$t.=chr(208).chr($c-48); continue; }
       if ($c>=208 && $c<=239) {$t.=chr(208).chr($c-48); continue; }
       if ($c>=240 && $c<=255) {$t.=chr(209).chr($c-112); continue; }
       if ($c==184) { $t.=chr(209).chr(209); continue; };
       if ($c==168) { $t.=chr(208).chr(129); continue; };
   }
   return $t;
}
?>

Check this code -- exelent to convert win-1251 to UTF-8 
just one fix!!!
       if ($c==184) { $t.=chr(209).chr(145); continue; }; 

Anything more it is not necessary.

i tried all functions here to convert from cp1251 to unicode, but they don't work. i think that this work : 

<?php 
function win3utf($s)    { 
   for($i=0, $m=strlen($s); $i<$m; $i++)    { 
       $c=ord($s[$i]); 
       if ($c<=127) {$t.=chr($c); continue; } 
       if ($c>=192 && $c<=207)    {$t.=chr(208).chr($c-48); continue; } 
       if ($c>=208 && $c<=239) {$t.=chr(208).chr($c-48); continue; } 
       if ($c>=240 && $c<=255) {$t.=chr(209).chr($c-112); continue; } 
       if ($c==184) { $t.=chr(209).chr(209); continue; }; 
   if ($c==168) { $t.=chr(208).chr(129);  continue; }; 
   } 
   return $t; 
} 
?>

Unfortunately input data must be a string only. But it is may be changed! ;) 

To convert multi-dimensional array I use this recursive function:

<?php
function convert_cyr_array($array,$from,$to){
    foreach($array as $key=>$value){
        if(is_array($value)) {
            $result[$key] = convert_cyr_array($value,$from,$to);
            continue;
        }
        $result[$key] = convert_cyr_string($value,$from,$to);
    }
    return $result;
}
?>

An example:

<?php
$array[0] = "сВМПЛП";
$array[1] = "зТХЫБ";
$array[2] = array("пЗХТЕГ","рПНЙДПТ");
$array[3] = array(
                     array("бРЕМШУЙО","нБОДБТЙО"),
                     array("бВТЙЛПУ","рЕТУЙЛ")
                );

$result = convert_cyr_array($array,"k","w");
/* Returns:

Array
(
  [0] => Яблоко
  [1] => Груша
  [2] => Array
    (
      [0] => Огурец
      [1] => Помидор
    )
  [3] => Array
    (
      [0] => Array
        (
          [0] => Апельсин
          [1] => Мандарин
        )
      [1] => Array
        (
          [0] => Абрикос
          [1] => Персик
        )
    )
)*/

You function doesn't work on my PC..
It's work:
function Encode2($str,$type)
{
    $conv=array();
    for($x=192;$x<=239;$x++)
        $conv[u][chr($x)]=chr(208).chr($x-48);
    for($x=240;$x<=255;$x++)
        $conv[u][chr($x)]=chr(209).chr($x-112);
    $conv[u][chr(168)]=chr(208).chr(129);
    $conv[u][chr(184)]=chr(209).chr(209);
    $conv[w]=array_reverse($conv[u]);
    if($type=='w' || $type=='u')
        return strtr($str,$conv[$type]);
    else
        return $str;
}

i tried all functions here to convert from cp1251 to unicode, but they don't work. i think that this work :

<?php
