PHP获取远程网站标题及简介说明
本帖最后由 mingniu66 于 2013-11-20 16:32:18 编辑
header("Content-Type:text/html;charset=utf-8");
$url = 'http://cm100.net/';
//获取远程网页的编码
function _charset($url){
$text = file_get_contents($url);
$mode = '/charset=(.*)\"/iU';
preg_match($mode,$text,$result);
return $result[1];
}
$charset = _charset($url);//获取远程网页的编码
//以上为公用
//1：获取远程网页的标题，$url地址,$charset用于判断编码
function _title($url,$charset){
$text = file_get_contents($url);
//如果是gb2312编码处理乱码
if ($charset == 'gb2312'){
$text = iconv('gb2312','utf-8',$text);
}
$mode = '/(.*)/iU';<br>
preg_match($mode,$text,$result);<br>
return $result[1];<br>
}<br>
echo '网站标题：'.$title = _title($url,$charset); //获取远程网页的标题<br><br><br><br>
//2：获取远程网页的简介<br>
function _description($url,$charset){<br>
$text = file_get_contents($url);<br><br>
//gb2312编码乱码处理<br>
if ($charset == 'gb2312'){<br>
$text = iconv('gb2312','utf-8',$text);<br>
}<br><br>
$mode = '/<meta>/iU';<br>
preg_match($mode,$text,$result);<br>
return $result[1];<br><br>
}<br>
echo '网站简介：'.$description = _description($url,$charset); //获取远程网页的简介<br>

初学PHP,想要获取远程网站的标题及简介，网上查了好几天写出来的结果，勉强能达到想要的结果，获取速度有点慢，感觉代码很乱，不知道有没有更好的方法，

应该只有1个函数用来file_get_contents获取内容，然后将内容传给每个函数来匹配结果！ <div class="clear">
