这篇文章主要介绍了PHP获取网页标题的3种实现方法,分别使用CURL、file()函数、file_get_contents实现,需要的朋友可以参考下
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("/", $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,'');
$length=$poste-$postb;
echo substr($content,$postb,$length);
?>
