请问一个PHP Url encode 的问题

[liq330]

It is SMS content. For Unicode of each message should be equal or less than 70 characters. For ASCII of each message should be equal or less than 160 characters. If the message is longer than one message length, it will be counted as two messages.
All non-English messages should be formatted in Unicode with URL Encoding.
For Example,

“網頁” => %26%2332178%3B%26%2338913%3B
”网页” => %26%2332593%3B%26%2339029%3B

这是一个用接口发短信的说明文档。

可是我用很多方法包括 urlencode 转成 ascii 再 urlencode 什么都无法生成例子中的样子，发过去的都是乱码

请问一下这个是怎么转的？


“網頁” => %26%2332178%3B%26%2338913%3B
”网页” => %26%2332593%3B%26%2339029%3B

$a = '网页';
$b = mb_encode_numericentity( $a, array( 0x0080, 0xffff, 0, 0xffff ), 'UTF-8' );
$c = urlencode($b);
var_dump($c);

網頁不是乱码，而是繁体字而已吧，至于怎么转，我不是很清楚，帮顶！
