$str
, array $convmap
[, string $encoding
= mb_internal_encoding()
[, bool $is_hex
= FALSE
]] )
Converts
specified character codes in string str
from character code to HTML numeric character reference.
str
The string being encoded.
convmap
convmap
is array specifies code area to
convert.
encoding
encoding
参数为字符编码。如果省略,则使用内部字符编码。
is_hex
The converted string .
版本 | 说明 |
---|---|
5.4.0 |
Added is_hex parameter.

Example #1 convmap
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
$convmap = array( 0x80 , 0xff , 0 , 0xff );
$str = mb_encode_numericentity ( $str , $convmap , "ISO-8859-1" );
$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 ,
0xe234 , 0xe272 , 0x110c , 0xffff ,
0xe273 , 0xe2ef , 0x110d , 0xffff ,
0xe2f0 , 0xe32e , 0x1150 , 0xffff ,
0xe32f , 0xe3ab , 0x1151 , 0xffff );
$str = mb_encode_numericentity ( $str , $convmap , "sjis-win" );
?>

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

To get Unicode numbers out of a UTF-8 string, this can be used, for example:
<?php
print mb_encode_numericentity ('s??????', 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(
160, 255, 0, $f,
402, 402, 0, $f, 913, 929, 0, $f, 931, 937, 0, $f,
