他是怎么绕过注册10字符限制的？？？
我看到是很多空格。。。
但是正常的输入空格没道理会成功的。。

有爱好者来帮我找找原因吧。

关于过滤的写法

public function transform($txt)<br />    {<br />        $txt = trim($txt);<br />        $txt = addslashes(htmlspecialchars($txt, ENT_QUOTES, "UTF-8"));<br />        if (preg_match_all("/\<fieldset><legend>Quote:</legend><blockquote>(.+?)\[\/quote]/is", $txt, $match)) {<br />            $txt = preg_replace('/\s*\r\n\s*/', '', $txt, 1);<br />        }<br />        $huanhang = array(<br />            "\r\n",<br />            "\n",<br />            "\r"<br />        );<br />        $txt      = str_replace($huanhang, '<br>', $txt);

Copy after login

图片显示：文字到省略号间有一段空白
连浏览器都不认为是半角空格，你还 \s 有何用？
