我有一个网站，我想检测使用哪个浏览器并将其重定向. 我有一个php索引，并且代码必须在php中. 我发现了很多网站，但它们无法正常工作，或者它们无法检测到许多移动浏览器. 您是否知道可以检测许多移动浏览器的任何好的代码或教程?

I have a site and I want to detect which browser is used and redirect them. I have a php index and the code must be in php. I've found many sites but they don't work or they don't detect many mobile browsers. Do you know of any good code or tutorials that can detect many mobile browsers?

推荐答案

具有我的用户代理代码:

Have my user agent code:

<?php

/* USER-AGENTS
================================================== */
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 ( "/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;
}

?>

使用方法:

<?php
$ismobile = check_user_agent('mobile');
if($ismobile) {
return 'yes';
} else {
return 'no';
}
?>
