    mb_encode_numericentity — Codifica los caracteres en referencia numérica HTML

    Descripción

    mb_encode_numericentity(
        string $string,
        array $map,
        ?string $encoding = null,
        bool $hex = false
    ): string

    Convierte los códigos de los caracteres especificados de la string string a referencia numérica HTML.

    Parámetros

    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).

    Valores devueltos

    La string convertida.

    Errores/Excepciones

    Genera una excepción ValueError si map no es una lista de enteros.

    Historial de cambios

    Versión Descripción
    8.4.0 mb_encode_numericentity() ahora genera una excepción ValueError si map no es una lista de enteros.
    8.0.0 encoding is nullable now.

    Ejemplos

    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) "&#97;&#65;&#230;&#198;&#12354;&#12450;&#40509;"
string(28) "aA&#230;&#198;あア&#40509;"

    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,
