一、推荐方法 CURL获取
$c = curl_init();
$url = 'www.jb51.net';
curl_setopt($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",$data);}
preg_match("/
(.*)/i",$data, $title);<br>echo $title[1];<br>?>
<p>二、使用file()函数</p>
<p><?php <BR>$lines_array = file('http://www.jb51.net/');<br>$lines_string = implode('', $lines_array); <br>$pos = strpos($lines_string,'utf-8');<br>if($pos===false){$lines_string = iconv("gbk","utf-8",$lines_string);}<br>eregi("</p>
<title>(.*)", $lines_string, $title);
echo $title[1];
?>
三、使用file_get_contents
$content=file_get_contents("http://www.jb51.net/");
$pos = strpos($content,'utf-8');
if($pos===false){$content = iconv("gbk","utf-8",$content);}
$postb=strpos($content,'
')+7;<br>$poste=strpos($content,'');
$length=$poste-$postb;
echo substr($content,$postb,$length);
?>
