本文章来给大家介绍php反中文汉字转Unicode编码实现程序方法，有需要了解的朋友可进入参考。
程序
| 代码如下 |
复制代码 |
/**
* $str 原始字符串
* $encoding 原始字符串的编码，默认GBK
* $prefix 编码后的前缀，默认""
* $postfix 编码后的后缀，默认";"
*/
function unicode_encode($str, $encoding = 'GBK', $prefix = '', $postfix = ';') {
$str = iconv($encoding, 'UCS-2', $str);
$arrstr = str_split($str, 2);
$unistr = '';
for($i = 0, $len = count($arrstr); $i $dec = hexdec(bin2hex($arrstr[$i]));
$unistr .= $prefix . $dec . $postfix;
}
return $unistr;
}
/**
* $str Unicode编码后的字符串
* $encoding 原始字符串的编码，默认GBK
* $prefix 编码字符串的前缀，默认""
* $postfix 编码字符串的后缀，默认";"
*/
function unicode_decode($unistr, $encoding = 'GBK', $prefix = '', $postfix = ';') {
$arruni = explode($prefix, $unistr);
$unistr = '';
for($i = 1, $len = count($arruni); $i if (strlen($postfix) > 0) {
$arruni[$i] = substr($arruni[$i], 0, strlen($arruni[$i]) - strlen($postfix));
}
$temp = intval($arruni[$i]);
$unistr .= ($temp }
return iconv('UCS-2', $encoding, $unistr);
} |
使用范例：
| 代码如下 |
复制代码 |
//GBK字符串测试
$str = '哈哈';
echo $str.'
';
$unistr = unicode_encode($str);
echo $unistr.'
'; // 哈哈
$str2 = unicode_decode($unistr);
echo $str2.'
'; //哈哈
//UTF-8字符串测试
$utf8_str = iconv('GBK', 'UTF-8', $str);
echo $utf8_str.'
'; // ???? 注：UTF在GBK下显示的乱码！可切换浏览器的编码测试
$utf8_unistr = unicode_encode($utf8_str, 'UTF-8');
echo $utf8_unistr.'
'; // 哈哈
$utf8_str2 = unicode_decode($utf8_unistr, 'UTF-8');
echo $utf8_str2.'
'; // ????
//其它后缀、前缀测试
$prefix_unistr = unicode_encode($str, 'GBK', "u", '');
echo $prefix_unistr.'
'; // u60u98u62u21704u21704u60u47u98u62
$profix_unistr2 = unicode_decode($prefix_unistr, 'GBK', "u", '');
echo $profix_unistr2.'
'; //哈哈 |
