PHP获取当前网页的标题和内容

有时候我们需要获取网页的标题与内容，就是个采集函数，这里简单分享下，方便需要的朋友，

代码如下:

$c = curl_init();

$url = 'blog.0735dj.com';

curl_setopt($c, CURLOPT_URL, $url);

curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);

$data = curl_exec($c);

curl_close($c);

$pos = strpos($data,'utf-8');

if($pos===false){$data = iconv("gbk","utf-8",$data);}

preg_match("/<title>(.*)<\/title>/i",$data, $stitle);

eregi("</head>(.*)</body>",$data,$sbody);

$title = $stitle[1];//获取标题

$slbody = preg_replace(array("'<style(.*?)>(.*?)</style>'is","'<script(.*?)>(.*?)</script>'is","/<\/?[^>]+>/i"),'',$sbody[1]);//获取纯文本内容
