I came across a bug (and workaround) when using recode_string. When converting from utf-8 to iso-2022-jp, it would always return an empty string (although it would work fine for conversions from html to utf8). Converting with recode on the command line worked fine, which was odd. I noticed that if I specified "-v" on the command line, recode stated that it was using libiconv to do the conversion.

Using "iconv" instead of recode got the right results.
i.e.

Works:
$str = recode_string("html..utf-8", "&#26085;&#26412;&#35486;"); // Unicode for "Japanese"

Doesn't work:
$str = recode_string("utf-8..iso-2022-jp", $mystring);

Works:
$str = iconv("utf-8", "iso-2022-jp", $mystring);

Don't ask me why. Hope this saves someone some frustrating hours debugging.

Here's how to convert romaji to katakana/hiragana with PHP (transliterating Japanese text).
The function Romaji2Kana($s) will return with keys 'hira' and 'kata' that respectively contain the hiragana and katakana versions of the given string in UTF-8 encoding.

<?php
// eucjp: 2421; unicode: 3041
define('HIRATABLE', 'a A i I u U e E o O KAGAKIGIKUGUKEGEKOGOSAZASIZISUZUSEZESOZO'.
'TADATIDItuTUDUTEDETODONANINUNENOHABAPAHIBIPIHUBUPUHEBEPEHOBOPO'.
'MAMIMUMEMOyaYAyuYUyoYORARIRUREROwaWAWIWEWOn ');
// eucjp: 2521; unicode: 30A1
define('KATATABLE', 'a A i I u U e E o O KAGAKIGIKUGUKEGEKOGOSAZASIZISUZUSEZESOZO'.
'TADATIDItuTUDUTEDETODONANINUNENOHABAPAHIBIPIHUBUPUHEBEPEHOBOPO'.
'MAMIMUMEMOyaYAyuYUyoYORARIRUREROwaWAWIWEWOn VUkake');

function
HiraTrans($s)
{
#print "trans('$s')\n";
$pos = strpos(HIRATABLE, $s);
if(
$pos===false) return 0xA1BC; // ^
return 0xA4A1 + $pos/2;
}
function
KataTrans($s)
{
$pos = strpos(KATATABLE, $s);
if(
$pos===false) return 0xA1BC; // ^
return 0xA5A1 + $pos/2;
}

function
Romaji2Kana($s)
{
$s = strtoupper(str_replace(
Array(
'shi', 'sh', 'fu', 'chi', 'ch', 'tsu', 'dz', 'l', '-',
'â', 'î', 'û', 'ê', 'ô', 'ā', 'ī', 'ū', 'ē', 'ō'),
Array(
'si', 'sy', 'hu', 'ti', 'ty', 'tu', 'j', 'r', '^',
'a^', 'i^', 'u^', 'e^', 'o^', 'a^', 'i^', 'u^', 'e^', 'o^'),
$s));
// FO -> FUxo
$s = preg_replace('@F([AIOE])@e', '"HU".strtolower("\1")', $s);
// VO -> VUxo
$s = preg_replace('@V([AIUEO])@e', '"VU".strtolower("\1")', $s);
// KYA -> KYya
$s = preg_replace('@([KSTNHMRGZBPD])Y([AUO])@e', '"\1Iy".strtolower("\2")', $s);
// XTU -> tu (make them actually small)
$s = preg_replace('@X(TU|Y[AUO]|[AIUEO]|KA|KE)@e', 'strtolower("\1")', $s);
// KKO -> tuKO
$s = preg_replace('@([KSTHMRYWGZBPDV]{2,})@e',
'str_pad("",2*strlen("\1")-2,"tu").substr("\1",0,1)', $s);
// N -> n (but not NO -> nO)
// At this point, N' will work correctly
$s = preg_replace('@N(?![AIUEO])@', 'n', $s);
// Unrecognized characters off
$s = eregi_replace('[^^VAIUEOKSTNHMYRWGZBPD]', '', $s);

$pat = '@([AIUEOnaiueo^]|..)@e';
$rec = 'EUCJP..UTF8';

return
Array(
'hira' => recode_string($rec,preg_replace($pat, 'pack("n", HiraTrans("\1"))', $s)),
'kata' => recode_string($rec,preg_replace($pat, 'pack("n", KataTrans("\1"))', $s)));
}

print_r( Romaji2Kana('konnichiha') );
?>

Note: Due to technical limitations in the manual pages, there are two errors in this code:
- Some characters in the first str_replace may appear wrong in some php.net mirrors. It supposed to contain aiueo with circumflex and aiueo with macron.
- The strings in the defines should be constant, not appendage expressions. (Line length limitation)

Seems to require that librecode be installed.
Try iconv() instead.

function Romaji2Kana works pretty good but few exception: "JA" and "DZA" were not converted correctly as Japanese speekes expected. Following is a correction of that behavior.

public function convert($s, $mode='hiragana')
{
$s = strtoupper(str_replace(
- Array('shi', 'sh', 'fu', 'chi', 'ch', 'tsu', 'dz', 'l', '-',
+ Array('shi', 'sh', 'fu', 'chi', 'ch', 'tsu', 'dzi', 'ji', 'j', 'l', '-',
'â', 'î', 'û', 'ê', 'ô', 'ā', 'ī', 'ū', 'ē', 'ō'),
- Array('si', 'sy', 'hu', 'ti', 'ty', 'tu', 'j', 'r', '^',
+ Array('si', 'sy', 'hu', 'ti', 'ty', 'tu', 'zi', 'zi', 'dz','r', '^',
'a^', 'i^', 'u^', 'e^', 'o^', 'a^', 'i^', 'u^', 'e^', 'o^'),
$s));
+ // DZA -> ZIya
+ $s = preg_replace('/DZ([AUO])/e', '"ZI".strtolower("y\1")', $s);
+ // DZE -> ZIe
+ $s = preg_replace('/DZ([E])/e', '"ZI".strtolower("\1")', $s);
// FO -> FUxo
$s = preg_replace('@F([AIOE])@e', '"HU".strtolower("\1")', $s);
// VO -> VUxo
