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?
我有一个网站，我想检测使用的是哪个浏览器并重定向它们。我有一个 php 索引，代码必须在 php 中。我找到了很多网站，但它们不起作用，或者它们没有检测到许多移动浏览器。您知道可以检测许多移动浏览器的任何好的代码或教程吗？

Have my user agent code:
有我的用户代理代码：
<?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;
}
?>

I wrote this script to detect a mobile browserin PHP.
The code detects a user based on the user-agent string by preg_match()ing. It has 100% accuracy on all current mobile devices and I'm currently updating it to support more mobile devices as they come out. The code is called isMobile and is as follows:
该代码通过 preg_match()ing 根据用户代理字符串检测用户。它在所有当前的移动设备上都具有 100% 的准确性，我目前正在更新它以支持更多的移动设备。代码名为isMobile，如下：
function isMobile() {
return preg_match("/(android|avantgo|blackberry|bolt|boost|cricket|docomo|fone|hiptop|mini|mobi|palm|phone|pie|tablet|up\.browser|up\.link|webos|wos)/i", $_SERVER["HTTP_USER_AGENT"]);
}
You can use it like this:
你可以这样使用它：
// Use the function
if(isMobile())
// Do something for only mobile users
else
// Do something for only desktop users
To redirect a user to your mobile site, I would do this:
要将用户重定向到您的移动网站，我会这样做：
// Create the function, so you can use it
function isMobile() {
return preg_match("/(android|avantgo|blackberry|bolt|boost|cricket|docomo|fone|hiptop|mini|mobi|palm|phone|pie|tablet|up\.browser|up\.link|webos|wos)/i", $_SERVER["HTTP_USER_AGENT"]);
}
// If the user is on a mobile device, redirect them
if(isMobile())
header("Location: http://m.yoursite.com/");
Let me know if you have any questions and good luck!
如果您有任何问题，请告诉我，祝您好运！
