实现代码如下：

<?php
/**
 * php curl采集Discuz
 * www.jb200.com
*/
set_time_limit(0);

//cookie保存目录
$cookdir = './cookie.tmp';

//模拟请求数据
Function request($url,$action,$cookdir,$referer){
    $ch = curl_init();
    $options = array(CURLOPT_URL => $url,
        CURLOPT_HEADER => 0,
        CURLOPT_NOBODY => 0,
        CURLOPT_PORT => 80,
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => $action,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_FOLLOWLOCATION => 1,
        CURLOPT_COOKIEJAR => $cookdir,
        CURLOPT_COOKIEFILE => $cookdir,
        CURLOPT_REFERER => $referer
    );
    curl_setopt_array($ch, $options);
    $code = curl_exec($ch);
    curl_close($ch);
    return $code;
}

//获取帖子列表
Function getList($code){
    //<a href="viewthread.php?tid=16&extra=page%3D1">加打塔洗花腳本</a>
    preg_match_all('/<a href="viewthread.php?tid=(d+)/',$code,$threads);
    return $threads[1];
}

//判断该帖子是否存在
Function isExits($code){
    preg_match('/<p>指定的主题不存在或已被删除或正在被审核，请返回。</p>/',$code,$error);
    return isset($error[0])?false:true;
}

//获取帖子标题
Function getTitle($code){
    preg_match('/<h1>[^</h1>]*/',$code,$title_tmp);
    $title = $title_tmp[0];
    return $title;
}

//登录论坛/
$url = 'http://www.jb200.com/logging.php?action=login';
$action='loginfield=username&username=see7di&password=fjin999&questionid=0&cookietime=315360000&referer=http://bbs.war3.cn/&loginsubmit=提交';
request($url,$action,$cookdir,'');
unset($action,$url);

//获取帖子列表(位于第一页的帖子)
$url = 'http://www.jb200.com/forumdisplay.php?fid=5';
$code = request($url,'',$cookdir,'');
$tList = getList($code);

//循环抓取每個帖子內的標題
foreach($tList as $list){
    $url = "http://www.jb200.com/viewthread.php?tid={$list}";
    $code = request($url,'',$cookdir,'');
    if(isExits($code)){
        $title = getTitle($code);
        echo "tid:{$list}:",strip_tags($title),"<br>";
    }else{
        echo "tid:{$list}:该帖子不存在!<br>";
    }
}
