Check if PHP-page is accessed from an iOS device
提问by Snilleblixten
I have a simple PHP webpage, and would like to return different content depending if it's accessed from an iPhone/iPad or from a web brower. How can I do that?
我有一个简单的 PHP 网页，并希望返回不同的内容，具体取决于它是从 iPhone/iPad 还是从网络浏览器访问。我怎样才能做到这一点？

Use the user agent from $_SERVER['HTTP_USER_AGENT'],
and for simple detection you can use thisscript:
使用来自 的用户代理$_SERVER['HTTP_USER_AGENT']，为了简单检测，您可以使用此脚本：
<?php
//Detect special conditions devices
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android");
$webOS = stripos($_SERVER['HTTP_USER_AGENT'],"webOS");
//do something with this information
if( $iPod || $iPhone ){
//browser reported as an iPhone/iPod touch -- do something here
}else if($iPad){
//browser reported as an iPad -- do something here
}else if($Android){
//browser reported as an Android device -- do something here
}else if($webOS){
//browser reported as a webOS device -- do something here
}
?>
If you want to know more details of the user device I recommended to use one of the following solutions: http://51degrees.mobior http://deviceatlas.com
如果您想了解用户设备的更多详细信息，我建议您使用以下解决方案之一：http: //51degrees.mobi或http://deviceatlas.com

preg_match("/iPhone|Android|iPad|iPod|webOS/", $_SERVER['HTTP_USER_AGENT'], $matches);
$os = current($matches);
switch($os){
case 'iPhone': /*do something...*/ break;
case 'Android': /*do something...*/ break;
case 'iPad': /*do something...*/ break;
case 'iPod': /*do something...*/ break;
case 'webOS': /*do something...*/ break;
}

function user_agent(){
$iPod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = strpos($_SERVER['HTTP_USER_AGENT'],"iPad");
$android = strpos($_SERVER['HTTP_USER_AGENT'],"Android");
file_put_contents('./public/upload/install_log/agent',$_SERVER['HTTP_USER_AGENT']);
if($iPad||$iPhone||$iPod){
return 'ios';
}else if($android){
return 'android';
}else{
return 'pc';
}

function isIosDevice(){
$userAgent = strtolower($_SERVER['HTTP_USER_AGENT']);
$iosDevice = array('iphone', 'ipod', 'ipad');
$isIos = false;
foreach ($iosDevice as $val) {
if(stripos($userAgent, $val) !== false){
$isIos = true;
break;
}
}
return $isIos;

51Degrees' PHP solution is able to do this. you can get the free Open Source API here https://github.com/51Degrees/Device-Detection. You can use the HardwareFamily Property to determine if it is an iPad/iPod/iPhone etc.
51Degrees 的 PHP 解决方案能够做到这一点。你可以在这里获得免费的开源 API https://github.com/51Degrees/Device-Detection。您可以使用 HardwareFamily 属性来确定它是否是 iPad/iPod/iPhone 等。
Due to the nature of Apple's User-Agents the initial result will return a generic device, however if you are interested in the specific device you can use a JavaScript client side override to determine to specific model.
由于 Apple 用户代理的性质，初始结果将返回通用设备，但是如果您对特定设备感兴趣，您可以使用 JavaScript 客户端覆盖来确定特定模型。
To do this you can implement something similar to the following logic once you have determined it is an Apple Device, in this case for an iPhone.
为此，您可以在确定它是 Apple 设备（在本例中为 iPhone）后实现类似于以下逻辑的内容。
// iPhone model checks.
function getiPhoneModel() {
// iPhone 6 Plus
if ((window.screen.height / window.screen.width == 736 / 414) &&
(window.devicePixelRatio == 3)) {
return "iPhone 6 Plus";
}
// iPhone 6
else if ((window.screen.height / window.screen.width == 667 / 375) &&
(window.devicePixelRatio == 2)) {
return "iPhone 6";
}
// iPhone 5/5C/5S or 6 in zoom mode
else if ((window.screen.height / window.screen.width == 1.775) &&
(window.devicePixelRatio == 2)) {
return "iPhone 5, 5C, 5S or 6 (display zoom)";
}
// iPhone 4/4S
else if ((window.screen.height / window.screen.width == 1.5) &&
(window.devicePixelRatio == 2)) {
return "iPhone 4 or 4S";
}
// iPhone 1/3G/3GS
else if ((window.screen.height / window.screen.width == 1.5) &&
(window.devicePixelRatio == 1)) {
return "iPhone 1, 3G or 3GS";
} else {
return "Not an iPhone";
};
}
Or for an iPad
或者 iPad
function getiPadVersion() {
var pixelRatio = getPixelRatio();
var return_string = "Not an iPad";
if (pixelRatio == 1 ) {
return_string = "iPad 1, iPad 2, iPad Mini 1";
}
if (pixelRatio == 2) {
return_string = "iPad 3, iPad 4, iPad Air 1, iPad Air 2, iPad Mini 2, iPad
Mini 3";
}
return return_string;
}

In response to Haim Evgi's code, I added !== false to the end for it to work for me
为了响应 Haim Evgi 的代码，我在末尾添加了 !== false 以使其对我有用
$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod") !== false;
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone") !== false;

If you just want to detect mobile devices in generel, Cake has build in support using RequestHandler->isMobile() (http://book.cakephp.org/2.0/en/core-libraries/components/request-handling.html#RequestHandlerComponent::isMobile)
如果你只是想检测一般的移动设备，Cake 已经使用 RequestHandler->isMobile() ( http://book.cakephp.org/2.0/en/core-libraries/components/request-handling.html# RequestHandlerComponent::isMobile)
