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();
$url = 'www.shuyong.net';
curl_setopt($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
