html实体转换,字符串html实体转换

原字符串：http://www.qdta.cn/xxw/xxInfo.asp?xxlx=旅游热讯&id=12939

想要转换成：http://www.qdta.cn/xxw/xxInfo.asp?xxlx=旅游热讯&id=12939

请问用什么函数？

回复讨论(解决方案)

function unescape($str) { $str = rawurldecode($str); preg_match_all("/(?:%u.{4})|.{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) == "") $ar[$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})|.{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) == "") $ar[$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);}

原来要自己写函数呀。只是不明白的是，为何有些要转换成utf-8格式？我是gbk，输出之后，是乱码，我把utf-8改成gbk就输出正常的中文了

有一种方法，直接用JS好了，如

code=26053;str = String.fromCharCode(code);document.write(str);

谢谢，不过这部分需要php处理的。
