PHP获取网页标题的2种实现方法代码实例

一、推荐方法 CURL获取

    $c = curl_init();
    $url = 'www.z6.net.cn';
    curl_setopt($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];

二、使用file_get_contents

    $content = file_get_contents("https://www.z6.net.cn/");
    $pos = strpos($content,'utf-8');
    if($pos===false){
        $content = iconv("gbk","utf-8",$content);
    }
    $postb = strpos($content,'');
    $length = $poste-$postb;
    echo substr($content,$postb,$length);
