停止在iPad上重定向移动网站

Question

我必须有两个站点，一个是我的主站点，另一个是移动站点。这是我在移动设备中使用时用于重定向移动网站的脚本。现在我想忽略iPad的移动网站重定向。我用过这个脚本，但它并没有忽视iPad，它仍然在iPad上的移动网站上重定向，我不想要这个。请帮忙。

 <?php
    function check_user_agent ( $type = NULL ) {
            $user_agent = strtolower ( $_SERVER['HTTP_USER_AGENT'] );
            if ( $type == 'bot' ) {
                    // matches popular bots
                    if ( preg_match ( "/googlebot|adsbot|yahooseeker|yahoobot|msnbot|watchmouse|pingdom.com|feedfetcher-google/", $user_agent ) ) {
                            return true;
                            // watchmouse|pingdom.com are "uptime services"
                    }
            } else if ( $type == 'browser' ) {
                    // matches core browser types
                    if ( preg_match ( "/mozilla/|opera//", $user_agent ) ) {
                            return true;
                    }
            } else if ( $type == 'mobile' ) {
                    // matches popular mobile devices that have small screens and/or touch inputs
                    // mobile devices have regional trends; some of these will have varying popularity in Europe, Asia, and America
                    // detailed demographics are unknown, and South America, the Pacific Islands, and Africa trends might not be represented, here

                   if( preg_match ( "/iPad/", $user_agent )) {
                            return false;
                    }  else if ( preg_match ( "/phone|iphone|itouch|ipod|symbian|android|htc_|htc-|palmos|blackberry|opera mini|iemobile|windows ce|nokia|fennec|hiptop|kindle|mot |mot-|webos/|samsung|sonyericsson|^sie-|nintendo/", $user_agent ) ) {
                            // these are the most common
                            return true;
                    } else if ( preg_match ( "/mobile|pda;|avantgo|eudoraweb|minimo|netfront|brew|teleca|lg;|lge |wap;| wap /", $user_agent ) ) {
                            // these are less common, and might not be worth checking
                            return true;
                    }
            }
            return false;
    }
    $ismobile = check_user_agent('mobile');
    if($ismobile) {
    header('Location:mobiles_site_url');
    } 
    ?>

您在用户代理字符串上使用了strtolower()，检查"iPad"的第一行中是否有大写字母。

尝试：

if( preg_match ( "/ipad/", $user_agent )) {  // all lower case
    ....
}
