汉字转换成Unicode编码PHP程序

下面来总结一些常用的汉字转换成Unicode编码PHP程序实现代码,我们只要了解到Unicode编码与gbk编码之间的内置转换原理即可了.

汉字转换成unicode方法,代码如下:

<?php
//将utf8编码的汉字转换为unicode
function htou($c) {
    $n = (ord($c[0]) & 0x1f) << 12;
    $n = (ord($c[1]) & 0x3f) << 6;
    $n = ord($c[2]) & 0x3f;
    return $n;
}
//在代码中隐藏utf8格式的字符串
function my_utf8_unicode($str) {
    $encode = &#39;&#39;;
    for ($i = 0; $i < strlen($str); $i) {
        if (ord(substr($str, $i, 1)) > 0xa0) {
            $encode.= &#39;&#&#39; . htou(substr($str, $i, 3)) . &#39;;&#39;;
            $i = 2;
        } else {
            $encode.= &#39;&#&#39; . ord($str[$i]) . &#39;;&#39;;
        }
    }
    return $encode;
}
echo my_utf8_unicode("哈哈ABC");
?>

汉字转换成unicode方法二,代码如下:

<?php
function getUnicode($word) {
    // 转UTF8
    $word0 = iconv(&#39;gbk&#39;, &#39;utf-8&#39;, $word);
    $word1 = iconv(&#39;utf-8&#39;, &#39;gbk&#39;, $word0);
    $word = ($word1 == $word) ? $word0 : $word;
    // 拆分汉字
    preg_match_all(&#39;#(?:[x00-x7F]|[xC0-xFF][x80-xBF]+)#s&#39;, $word, $array, PREG_PATTERN_ORDER);
    $return = array();
    // 转换
    foreach ($array[0] as $cc) {
        $arr = str_split($cc);
        $bin_str = &#39;&#39;;
        foreach ($arr as $value) {
            $bin_str.= decbin(ord($value));
        }
        $bin_str = preg_replace(&#39;/^.{4}(.{4}).{2}(.{6}).{2}(.{6})$/&#39;, &#39;$1$2$3&#39;, $bin_str);
        $return[] = &#39;&#&#39; . bindec($bin_str) . &#39;;&#39;;
    }
    return implode(&#39;&#39;, $return);
}
?>

函数用法,代码如下:

$word = '一个汉字转换成Ｕｎｉｃｏｄｅ四字节编码的PHP函数。'; 

echo getUnicode($word); 

/* 

上述将输出如下结果： 

一个汉字转换成Ｕｎ  

ｉｃｏｄｅ四字节编  

码的PHP函数。 

*/ 

这一组函数可以将汉字转成unicode编码,也可以将unicode解码成汉字. 

将汉字转成Unicode的函数,代码如下:

function uni_encode ($word) 
{ 
    $word0 = iconv('gbk', 'utf-8', $word); 
    $word1 = iconv('utf-8', 'gbk', $word0); 
    $word =  ($word1 == $word) ? $word0 : $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; 
}

对Unicode编码进行解码的函数,代码如下:

function uni_decode ($uncode) 
{ 
    $word = json_decode(preg_replace_callback('/&#(\d{5});/', create_function('$dec', 'return '\u'.dechex($dec[1]);'), '"'.$uncode.'"')); 
    return $word; 
}
