Examples

Example #1 map example

<?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 );
// Specify Unicode value for start_codeN and end_codeN
// Add offsetN to value and take bit-wise 'AND' with maskN, then
// it converts value to numeric string reference.
?>

Example #2 mb_encode_numericentity() example

<?php
/* Convert Left side of ISO-8859-1 to HTML numeric character reference */
$convmap = array(0x80, 0xff, 0, 0xff);
$str = mb_encode_numericentity($str, $convmap, "ISO-8859-1");

/* Convert user defined SJIS-win code in block 95-104 to numeric
string reference */
$convmap = array(
0xe000, 0xe03e, 0x1040, 0xffff,
0xe03f, 0xe0bb, 0x1041, 0xffff,
0xe0bc, 0xe0fa, 0x1084, 0xffff,
0xe0fb, 0xe177, 0x1085, 0xffff,
0xe178, 0xe1b6, 0x10c8, 0xffff,
0xe1b7, 0xe233, 0x10c9, 0xffff,

0xe273, 0xe2ef, 0x110d, 0xffff,
0xe2f0, 0xe32e, 0x1150, 0xffff,
0xe32f, 0xe3ab, 0x1151, 0xffff );

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,
