I didn't find Japanese sorting function. 

(mb_sort_kana or something)

Only SJIS encoding treats hankaku kata kana,

 I can't post here copy & paste version script.

I'm sorry...

You will replace comments with appropriate japanese string,

and write exception handlings between lines as you like.



<?php

mb_internal_encoding("SJIS");



$moji = /*"aiueo...wawon -?.," <- serialized hankaku kata kana 50 on hyou goes here*/;

$moji .= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxwz0123456789";



for($i = 0; isset($moji[$i]); $i++){

    $pittan[$moji[$i]] = $i;

}



function cmp($a, $b)

{

   if ($a == $b) {

       return 0;

   }

   return iter(mb_convert_kana($a, "askh") ,mb_convert_kana($b, "askh"), 0);

}



function iter($a, $b, $i){

    global $pittan;

    if(!isset($a[$i]) || !isset($b[$i])){

        return (isset($b[$i]))? -1 : 1;

    }

    if ($pittan[$a[$i]] == $pittan[$b[$i]]){

        return iter($a, $b, ++$i);

    }

    return (($pittan[$a[$i]]) < ($pittan[$b[$i]]))? -1 : 1;

}



echo "<pre>";

$arr = array(/*some japanese array here*/);

usort($arr, "cmp");

var_dump($arr);

?>

It seems that mb_convert_kana() doesn't convert symbols such as ' (single quoatation). It affected my program when I insert data into database. 



So, I've found 2 ways to solve this.

1) Use Javascript to convert those non-supported symbols before sending query string to your php page.

2) Use php function, str_replace $str, to replace those non-supported symbols. For example, $str = str_replace("'", "
