判断用户是否使用移动设备使用PHP浏览我的网站的最简单方法是什么?
我遇到过许多类，你可以使用，但我希望一个简单的if条件!
有什么办法可以让我这么做吗?

到目前为止，我一直在想，为什么没有人对使用implode()的公认答案稍加修改，以提高代码的可读性。所以是这样的:

$uaStart = substr($uaFull, 0, 4);

你也可以使用第三方api通过用户代理字符串进行设备检测。其中一个这样的服务是www.useragentinfo.co。只需注册并获得你的api令牌，以下是你如何通过PHP获得设备信息:
<?php
$useragent = $_SERVER['HTTP_USER_AGENT'];
// get api token at https://www.useragentinfo.co/
$token = "<api-token>";
$url = "https://www.useragentinfo.co/api/v1/device/";
$data = array('useragent' => $useragent);
$headers = array();
$headers[] = "Content-type: application/json";
$headers[] = "Authorization: Token " . $token;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
$json_response = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if ($status != 200 ) {
die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}
curl_close($curl);
echo $json_response;
?>
如果访问者使用的是iPhone，下面是示例回复:
{
"device_type":"SmartPhone",
"browser_version":"5.1",
"os":"iOS",
"os_version":"5.1",
"device_brand":"Apple",
"bot":false,
"browser":"Mobile Safari",
"device_model":"iPhone"
}
如果您的服务器支持get_browser(自PHP 4起可用)，则非常简单。它们有一个内置的功能来满足你的要求。
参考:https://www.php.net/manual/en/function.get-browser.php
<?php
$browser = get_browser(null, true);
if($browser['ismobiledevice']) {
// Device is mobile
}
?>
如果您关心屏幕大小，您可以将屏幕宽度和高度存储为cookie值(如果它们还不存在)，然后进行自页面重定向。
现在你在客户端和服务器端都有了cookie，可以用它来确定手机、平板电脑和其他设备
这里有一个快速的例子，你可以用JavaScript做到这一点。 警告![此代码包含伪代码]。
if (!getcookie("screen_size")) {
var screen_width = screen.width;
var screen_height = screen.height;
setcookie("screen_size", screen_width+", " +screen_height);
go2(geturl());
}
