<?php
//convert UTF8 encoded kanji to Unicode
function Htou ($c) {
  $n = (ord ($c [0]) & 0x1f) << 12;
  $n = (Ord ($c [1]) & 0x3f) << 6;
  $n = Ord ($c [2]) & 0x3f;
 return $n;
}

//Hide UTF8 format string in code
function My_utf8_unicode ($str) {
  $encode = ';
 for ($i =0; $i < Strlen ($STR); $i) {
  if (Ord (substr ($str, $i, 1)) > 0xa0) {
   $encode. = ' &# '. Htou (substr ($ STR, $i, 3)). '; ';
   $i = 2;
 }else{
   $encode. = ' &# '. Ord ($str [$i]).
 }
 }
 return $encode;
}

Echo my_utf8_unicode (haha abc);


Conversion of Chinese characters into Unicode method two


The code is as follows


function Getunicode ($word)
{
 //to UTF8
  $word 0 = iconv (' GBK ', ' utf-8 ', $word);
  $word 1 = iconv (' UT F-8 ', ' GBK ', $word 0);
  $word =  ($word 1 = $word)? $word 0: $word;
 //split Chinese characters
 preg_match_all (?: [x00-x7f]|[ xc0-xff][x80-xbf]+) #s ', $word, $array, Preg_pattern_order);
  $return   = array ();
 //Conversion
 foreach ($array [0] as $CC)
 {
   $arr = Str_split ($CC);
   $bin _str = ';
  foreach ($arr as $value)
  {
    $bin _str. = Decbin (ord ($value));
&NBSP;&NBSP}
   $bin _str = preg_replace ('/^.{ 4} (. { 4}). {2} (. {6}). {2} (. {6}) $/', ' $1$2$3 ', $bin _str);
   $return [] = ' &# '. Bindec ($bin _str). ';';
 }
 
 return implode (', $return);
}


Function usage:


The code is as follows

$word = ' Converts a Chinese character into a Unicode four-byte encoded PHP function. ';
echo Getunicode ($word);


The above results will be output as follows:



& #19968 & #20010 & #27721 & #23383 & #36716 & #25442 & #25104 & #65333 & #65358

& #30721 & #30340 & #80 & #72 & #80 & #20989 & #25968 & #12290



This set of functions converts Chinese characters into Unicode encoding, or it can decode Unicode into Chinese characters.
function to convert Chinese characters to Unicode:


The code is as follows

function Uni_encode ($word)
{
$word 0 = iconv (' GBK ', ' utf-8 ', $word);
$word 1 = iconv (' utf-8 ', ' GBK ', $word 0);
$word = ($word 1 = $word)? $word 0: $word;
$word = Json_encode ($word);
$word = Preg_replace_callback ('/\\u (w{4})/', create_function (' $hex ', ' return ' &# '. Hexdec ($hex [1]). '; '; ', substr ($word, 1, strlen ($word)-2));
return $word;
}


Functions to decode Unicode encoding:


  code is as follows

function Uni_decode ($uncode)
{
    $word = Json_decode (Preg_replace_callback ('/&# (d{5});/', create _function (' $dec ', ' return ' \u '. Dechex ($dec [1]); '), ' "'. $uncode. '");
    return $word;
}
