PHP UTF-8和Unicode编码互转
/** * //将内容进行UNICODE编码 * utf-8 转unicode * * @param string $name * @return string */ fu本2文来*源gao($daima.com搞@代@#码(网搞gaodaima代码nction utf8_unicode($name){ $name = iconv('UTF-8', 'UCS-2', $name); $len = strlen($name); $str = ''; for ($i = 0; $i 0){ //两个字节的文字 $str .= '\u'.base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT); //$str .= base_convert(ord($c), 10, 16).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT); } else { $str .= '\u'.str_pad(base_convert(ord($c2), 10, 16), 4, 0, STR_PAD_LEFT); //$str .= str_pad(base_convert(ord($c2), 10, 16), 4, 0, STR_PAD_LEFT); } } $str = strtoupper($str);//转换为大写 return $str; } /** * unicode 转 utf-8 * * @param string $name * @return string */ function unicode_decodessss($name) { $name = strtolower($name); // 转换编码,将Unicode编码转换成可以浏览的utf-8编码 $pattern = '/([\w]+)|(\\\u([\w]{4}))/i'; preg_match_all($pattern, $name, $matches); if (!empty($matches)) { $name = ''; for ($j = 0; $j < count($matches[0]); $j++) { $str = $matches[0][$j]; if (strpos($str, '\\u') === 0) { $code = base_convert(substr($str, 2, 2), 16, 10); $code2 = base_convert(substr($str, 4), 16, 10); $c = chr($code).chr($code2); $c = iconv('UCS-2', 'UTF-8', $c); $name .= $c; } else { $name .= $str; } } } return $name; }
调用及结果:
$utf8_str = '我';//这是汉字“你”的Unicode编码$unicode_str = '\u4f60';//输出 6211echo utf8_unicode($utf8_str) . "
";//输出汉字“你”echo unicode_decodes($unicode_str);
注: 由于浏览器默认会解读,所以要看源代码
\U6211
