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.45it.com';

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

$lines_array = file('http://www.45it.com/');

$lines_string = implode('', $lines_array);

$pos = strpos($lines_string,'utf-8');

if($pos===false){$lines_string = iconv("gbk","utf-8",$lines_string);}

eregi("

(.*)", $lines_string, $title);

echo $title[1];

?>

三、使用file_get_contents

$content=file_get_contents("http://www.45it.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);

?>
