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); echo $title[1]; ?> 二、使用file()函数 <?php $lines_array = file('http://www.jb51.net/'); $lines_string = implode('', $lines_array); $pos = strpos($lines_string,'utf-8'); if($pos===false){$lines_string = iconv("gbk","utf-8",$lines_string);} eregi("<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; $poste=strpos($content,'');
$length=$poste-$postb;
echo substr($content,$postb,$length);
?>
