实例如下：

//将内容进行UNICODE编码 function unicode_encode($name) { $name = iconv('UTF-8', 'UCS-2', $name); $len = strlen($name); $str = ''; for ($i = 0; $i < $len - 1; $i = $i + 2) { $c = $name[$i]; $c2 = $name[$i + 1]; if (ord($c) > 0) { // 两个字节的文字 $str .= '\u'.base_convert(ord($c), 10, 16).base_convert(ord($c2), 10, 16); } else { $str .= $c2; } } return $str; } $name = 'MY,你大爷的'; $unicode_name=unicode_encode($name); echo '<h3>'.$unicode_name.'</h3>'; // 将UNICODE编码后的内容进行解码 function unicode_decode($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 $name; } echo 'MY,\u4f60\u5927\u7237\u7684 -> '.unicode_decode($unicode_name);
