Question

我有一个名为index.php的页面，我有一个用于检测机器人的脚本，但它无法正常工作。如果机器人访问index.php，那么我想要包含welcome.php。如果它是原始用户，则不应包含welcome.php。这是我到目前为止所尝试的：

   function is_bot(){
   $botlist = array("Teoma", "alexa", "froogle", "Gigabot", "inktomi",
    "looksmart", "URL_Spider_SQL", "Firefly", "NationalDirectory",
    "Ask Jeeves", "TECNOSEEK", "InfoSeek", "WebFindBot", "girafabot",
    "crawler", "www.galaxy.com", "Googlebot", "Scooter", "Slurp",
    "msnbot", "appie", "FAST", "WebBug", "Spade", "ZyBorg", "rabaz",
    "Baiduspider", "Feedfetcher-Google", "TechnoratiSnoop", "Rankivabot",
    "Mediapartners-Google", "Sogou web spider", "WebAlta 
     Crawler","TweetmemeBot", "Butterfly", "Twitturls", "Me.dium", 
     "Twiceler", "Purebot", "facebookexternalhit",
    "Yandex", "CatchBot", "W3C_Validator", "Jigsaw","PostRank", 
    "Purebot", "Twitterbot",
    "Voyager", "zelist", "pingdom", "favicon");

   foreach($botlist as $bot){
    if(strpos($_SERVER['HTTP_USER_AGENT'],$bot)!==false)
    return true;    // Is a bot
    }
   return false;    // Not a bot
    }

以下是我遇到的主要问题 - 以下内容无效：

  if (is_bot()==true) {
session_destroy(); include_once('welcome.php'); exit; }

接下来，我尝试了这个，但它也没有工作：

  if (is_bot()) {
  session_destroy(); include_once('welcome.php'); exit; }

请就此情况提出任何解决方案。

每当我像这样使用它就会起作用

 if (is_bot())
 $isbot = 1;
 else
 $isbot = 0;

Answer 1

最好改进你的is_bot函数并使用正则表达式而不是长时间的繁忙搜索。

下面的内容可能会更有用。

function is_bot(){
    preg_match('/bot|curl|spider|google|twitter^$/i', $_SERVER['HTTP_USER_AGENT'], $matches);

    return (empty($matches)) ? false : true;
}

Answer 2

我很确定问题是代码有效（虽然优化和格式化不当 - @ Imran的解决方案更清晰）但是你正在测试它。

您的 UA字符串不包含＆＃34; bot＆＃34; string - 你不是服务器。使用Google Chrome开发工具，就像这样;

F12
CTRL + SHIFT + M
顶部的UA框并改变你的UA字符串以假装成其他人，例如＆＃34; Googlebot的＆＃34;然后测试一下。

只需访问一个网站并导航回您的网站，就不会模仿机器人的请求＆＃39;从那个网站，它仍然只是你！

以下代码是 100％在我的网站上工作。

function isBotDetected() {

    ) {
        return true; // 'Above given bots detected'
    }

    return false;

} // End :: isBotDetected()

使用php检测bot
