PHP中解码Javascript中的unicode字符串

php里来解js中的unicode编码（就是/u1234/u5678这种东西）没有内置函数真麻烦，找了半天终于找了个靠谱点的自定义函数，备份一下

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; }
