//採集html
function getwebcontent($url){
$ch = curl_init();
$timeout = 10;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
$contents = trim(curl_exec($ch));
curl_close($ch);
return $contents;
}


//獲得標題和url
$string =
getwebcontent('http://www.***.com/learn/zhunbeihuaiyun/jijibeiyun/2');
//正則匹配
  • 擷取標題和地址
    preg_match_all ("/
  • (.*)<\/a>/",$string, $out, PREG_SET_ORDER);
    foreach($out as $key => $value){
    $article['title'][] = $out[$key][2];
    $article['link'][] = "http://www.***.com/learn/article/".$out[$key][1];
    }
    //根據url擷取文章內容
    foreach($article['link'] as $key=>$value){
    $content_html = getwebcontent($article['link'][$key]);
    preg_match("/[\s|\S]*?<\/div>/",$content_html,$matches);
    $article[content][$key] = $matches[0];

    }
    //不轉碼還真不能儲存成檔案
    foreach($article[title] as $key=>$value){
    $article[title][$key] = iconv('utf-8', 'gbk', $value);//轉碼
    }
    //存入檔案
    $num = count($article['title']);
    for($i=0; $i<$num; $i++){
    file_put_contents("{$article[title][$i]}.txt", $article['content'][$i]);
    }
    ?>
