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');
?>
(PHP 4 >= 4.0.6, PHP 5, PHP 7, PHP 8)
mb_encode_numericentity — Codifica los caracteres en referencia numérica HTML
$string
,$map
,$encoding
= null
,$hex
= false
Convierte los códigos de los caracteres especificados de la string string
a referencia numérica HTML.
string
La string a codificar.
map
map
es un array que especifica los
códigos a convertir.
encoding
The encoding
parameter is the character encoding. If it is omitted or null
, the internal character
encoding value will be used.
hex
Si la entidad de referencia devuelta debe estar en notación hexadecimal (de lo contrario, está en notación decimal).
La string convertida.
Genera una excepción ValueError si
map
no es una lista de enteros.

mb_encode_numericentity() ahora genera una
excepción ValueError si map
no es una lista de enteros.

Ejemplo #1 Ejemplo con map
<?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 ); // Especifica los valores Unicode de inicio (start_codeN) y fin (end_codeN) // Añade offsetN al valor, y realiza una operación AND a nivel de bits con maskN, luego // convierte el valor obtenido en entidad numérica ?>
Ejemplo #2 Ejemplo con mb_encode_numericentity()
<?php
$str = "aAæÆあア𩸽";
/* Convierte todos los caracteres UTF-8 hasta 4 bytes en referencias numéricas HTML */
$convmap = [0, 0x1FFFFF, 0, 0x10FFFF];
var_dump(mb_encode_numericentity($str, $convmap, "utf8"));
/* Convierte únicamente los caracteres UTF-8 de 2 y 4 bytes en referencias numéricas HTML */
$convmap = [
0x80, 0x7FF, 0, 0x10FFFF,
0x10000, 0x1FFFFF, 0, 0x10FFFF,
];
var_dump(mb_encode_numericentity($str, $convmap, "utf8"));
?>
El ejemplo anterior mostrará :
string(46) "aAæÆあア鸽" string(28) "aAæÆあア鸽"

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">
