mb_decode_mimeheader
When I use this function, I had found an error.
Example)
------------------------
INPUT STRING1 : abc&
INPUT STRING2 : abc&#
------------------------
OUTPUT STRING : abc
------------------------
<?php
$input = 'abc&';
$convmap = array (0x0, 0xffff, 0, 0xffff);
$output = mb_decode_numericentity($intput, $convmap, 'UTF-8');
echo $output;
?>
result : abc
If an input string is finished with some characters such the beginning of NCR-form, this function remove that characters.
So, I use an trick.
<?php
function decode_numericentity($string){
$string = $string.chr(32);
$string = mb_decode_numericentity($string, $convmap, 'UTF-8');
$pos = strlen($string)-1;
//if(ord($string[$pos]) == 32){
$string = substr($string,0,$pos);
//}
return $string;
}
?>

Manual entity => utf8 conversion:
<?php
// parse entities
$raw = preg_replace_callback
(
"/&#(\\d+);/u",
"_pcreEntityToUtf",
$raw
);
function _pcreEntityToUtf($matches)
{
$char = intval(is_array($matches) ? $matches[1] : $matches);
if ($char < 0x80)
{
// to prevent insertion of control characters
if ($char >= 0x20) return htmlspecialchars(chr($char));
else return "&#$char;";
}
else if ($char < 0x8000)
{
return chr(0xc0 | (0x1f & ($char >> 6))) . chr(0x80 | (0x3f & $char));
}
else
{
return chr(0xe0 | (0x0f & ($char >> 12))) . chr(0x80 | (0x3f & ($char >> 6))). chr(0x80 | (0x3f & $char));
}
}

note that at this time it seems that mb_decode_numericentity() only works with decimal entities and not hexadecimal entities. This fact would have saved me a good hour of time in debugging.
For those who need to convert hex entities try first converting them all to decimal entities with a combination of the preg_replace() and hexdec() functions.

By use of function utf8_decode you'll get a problem with all extended chars above ISO-8859-1 charset. You can solve this problem by using the
function mb_encode_numericentity before:
// convert $text from UTF-8 to ISO-8859-1
$convmap = array(0xFF, 0x2FFFF, 0, 0xFFFF);
$text = mb_encode_numericentity($text, $convmap, "UTF-8");
$text = utf8_decode($text);
The second line encodes all extended chars below 0xFF, the third line converts the rest: 0x80 - 0xFF

Many web browsers will tend upload high order characters as UTF-8 encoded entities.
Here is some simple code to convert UTF-8 HTML entities within a block of text into proper characters:
<?php
//decode decimal HTML entities added by web browser
$body = preg_replace('/&#\d{2,5};/ue', "utf8_entity_decode('$0')", $body );
//decode hex HTML entities added by web browser
$body = preg_replace('/&#x([a-fA-F0-7]{2,8});/ue', "utf8_entity_decode('&#'.hexdec('$1').';')", $body );
//callback function for the regex
function utf8_entity_decode($entity){
$convmap = array(0x0, 0x10000, 0, 0xfffff);
return mb_decode_numericentity($entity, $convmap, 'UTF-8');
}
?>

Here are functions to convert hankaku to zenkaku characters (and vice-versa) in Japanese text.
<?php
// Supported characters:
// (space)
// !#$%&()*+,./0123456789:;<=>?@
// ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`
// abcdefghijklmnopqrstuvwxyz{|}
// (Katakana isn't supported.)
function f_han2zen ($string,$encoding = null) {
if (is_null($encoding)) $encoding = mb_internal_encoding();
$convmap = array(
0x20,0x20,0x3000-0x20,0xffff, // Space
0x21,0x7e,0xff01-0x21,0xffff);
$temp = mb_encode_numericentity($string,$convmap,$encoding);
$convmap = array(0,0xffff,0,0xffff);
return mb_decode_numericentity($temp,$convmap,$encoding);
}
function f_zen2han ($string,$encoding = null) {
if (is_null($encoding)) $encoding = mb_internal_encoding();
$convmap = array(
0x3000,0x3000,-(0x3000-0x20),0xffff, // Space
0xff01,0xff5e,-(0xff01-0x21),0xffff);
$temp = mb_encode_numericentity($string,$convmap,$encoding);
$convmap = array(0,0xffff,0,0xffff);
return mb_decode_numericentity($temp,$convmap,$encoding);
}
// Sample usage:
f_han2zen("test","shift_jis");
f_han2zen("test","utf-8");

Just two great functions for daily use:
/* Converts any HTML-entities into characters */
function my_numeric2character($t)
{
$convmap = array(0x0, 0x2FFFF, 0, 0xFFFF);
return mb_decode_numericentity($t, $convmap, 'UTF-8');
}
/* Converts any characters into HTML-entities */
function my_character2numeric($t)
{
$convmap = array(0x0, 0x2FFFF, 0, 0xFFFF);
return mb_encode_numericentity($t, $convmap, 'UTF-8');
}
print my_numeric2character('’ ἀ â');
print my_character2numeric(' ’ â ');
