复制代码 代码如下:

//采集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;

}

//获得标题和url

$string =

getwebcontent('http://www.***.com/learn/zhunbeihuaiyun/jijibeiyun/2');

//正则匹配<li>获取标题和地址

preg_match_all ("/<li><a href="/learn/article/(.*)">(.*)</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];

}

//根据url获取文章内容

foreach($article['link'] as $key=>$value){

$content_html = getwebcontent($article['link'][$key]);

preg_match("/<div id=pagenum_0(.*)>[s|S]*?</div>/",$content_html,$matches);

$article[content][$key] = $matches[0];

}

//不转码还真不能保存成文件

foreach($article[title] as $key=>$value){

$article[title][$key] = iconv('utf-8', 'gbk', $value);//转码

}

//存入文件

$num = count($article['title']);

for($i=0; $i<$num; $i++){

file_put_contents("{$article[title][$i]}.txt", $article['content'][$i]);

}
