PHP中UNICODE 编码和解码方法
方法一: <?php 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).str_pad(base_convert(ord($c2), 10, 16), 2, 0, STR_PAD_LEFT); } else { $str .= $c2; } } return $str; } //将UNICODE编码后的内容进行解码 function unicode_decode($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; $j <p>方法二:</p> <pre class="html " data-pbcklang="html" data-pbcktabsize="4">function unicode2utf8($str){ if(!$str) return $str; $decode = json_decode($str); if($decode) return $decode; $str = '["' . $str . '"]'; $decode = json_decode($str); if(count($decode) == 1){ return $decode[0]; } return $str; }
