例
例1 map の例
<?php
$convmap = array (
int start_code1, int end_code1, int offset1, int mask1,
int start_code2, int end_code2, int offset2, int mask2,
........
int start_codeN, int end_codeN, int offsetN, int maskN );
// start_codeN および end_codeN に Unicode 値を指定
// 値に offsetN を追加、マスク maskN を指定してビット毎の'AND'をとり、
// 数値エンティティに値を変換します。
?>

To get Unicode numbers out of a UTF-8 string, this can be used, for example:
<?php
print mb_encode_numericentity ('sāш日', array (0x0, 0xffff, 0, 0xffff), 'UTF-8');
?>

We were experiencing difficulties with PHP/Sablotron on Solaris; placing HTML character references into the XSL transformation, when set to output UTF-8, converts them back into UTF8 encoded chars. This was then a problem for non unicode storage. Using a bit of code from http://homepage.mac.com/marko/ the following function converts the string back to character references:
function utf2html ($utf2html_string)
{
$f = 0xffff;
$convmap = array(
/* <!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1//EN//HTML">
%HTMLlat1; */
160, 255, 0, $f,
/* <!ENTITY % HTMLsymbol PUBLIC "-//W3C//ENTITIES Symbols//EN//HTML">
%HTMLsymbol; */

To improve handling of EURO-Symbols in dan at boxuk dot com's function add the following line to $convmap:
128,128,0, $f,
