字串html實體轉換

原字串：http://www.qdta.cn/xxw/xxInfo.asp?xxlx=旅游热讯&id=12939
想要轉換成：http://www.qdta.cn/xxw/xxInfo.asp?xxlx=旅遊熱訊&id=12939
請問用什麼函數？

回複討論(解決方案)

function unescape($str) {  $str = rawurldecode($str);  preg_match_all("/(?:%u.{4})|&#x.{4};|&#\d+;|.+/U",$str,$r);  $ar = $r[0];print_r($ar);  foreach($ar as $k=>$v) {    if(substr($v,0,2) == "%u")      $ar[$k] = iconv("UCS-2","GB2312",pack("H4",substr($v,-4)));    elseif(substr($v,0,3) == "&#x")      $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));    elseif(substr($v,0,2) == "&#") {echo substr($v,2,-1)."
";      $ar[$k] = iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));    }  }  return join("",$ar);}

function unescape($str) {  $str = rawurldecode($str);  preg_match_all("/(?:%u.{4})|&#x.{4};|&#\d+;|.+/U",$str,$r);  $ar = $r[0];print_r($ar);  foreach($ar as $k=>$v) {    if(substr($v,0,2) == "%u")      $ar[$k] = iconv("UCS-2","GB2312",pack("H4",substr($v,-4)));    elseif(substr($v,0,3) == "&#x")      $ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));    elseif(substr($v,0,2) == "&#") {echo substr($v,2,-1)."
";      $ar[$k] = iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));    }  }  return join("",$ar);}

原來要自己寫函數呀。只是不明白的是，為何有些要轉換成utf-8格式？我是gbk，輸出之後，是亂碼，我把utf-8改成gbk就輸出正常的中文了

有一種方法，直接用JS好了，如

謝謝，不過這部分需要php處理的。
