PHP代码判断设备是手机还是平板电脑(两种方法)_PHP

May 30, 2016 am 08:44 AM

现在移动互联网越来越发达,很多的网站都普及了手机端浏览,为了更好的让网页在手机端显示,我们都选择了使用CSS媒体查询制作响应式模版,但这也有弊端,例如某些网站的结构是CMS类型的,太多的内容要显示,而使用CSS媒体查询设计响应式,只会隐藏但还是加载了,为了让手机端更快速的显示出内容,我们可以使用这个PHP判断手机设备代码,使用这个代码可以很方便的显示或不显示自定义的内容。

在做WEB开发的时候经常会需要用到对移动设备的页面匹配,当然可以直接把网站做成响应式的,但如果不想这么做的话,可以使用PHP对设备类型进行判断, 然后显示相应的界面和内容。今天分享一种使用 PHP 判断设备是否是手机/平板的方法,方法来源于WordPress(wp-includes/vars.php:125),适用于大部分类型的手机/平板判 断:

方法一:

/**
 * Test if the current browser runs on a mobile device (smart phone, tablet, etc.)
 *
 * @staticvar bool $is_mobile
 *
 * @return bool
 */
function wp_is_mobile() {
 static $is_mobile = null;
 
 if ( isset( $is_mobile ) ) {
  return $is_mobile;
 }
 
 if ( empty($_SERVER['HTTP_USER_AGENT']) ) {
  $is_mobile = false;
 } elseif ( strpos($_SERVER['HTTP_USER_AGENT'], 'Mobile') !== false // many mobile devices (all iPhone, iPad, etc.)
  || strpos($_SERVER['HTTP_USER_AGENT'], 'Android') !== false
  || strpos($_SERVER['HTTP_USER_AGENT'], 'Silk/') !== false
  || strpos($_SERVER['HTTP_USER_AGENT'], 'Kindle') !== false
  || strpos($_SERVER['HTTP_USER_AGENT'], 'BlackBerry') !== false
  || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mini') !== false
  || strpos($_SERVER['HTTP_USER_AGENT'], 'Opera Mobi') !== false ) {
   $is_mobile = true;
 } else {
  $is_mobile = false;
 }
 
 return $is_mobile;
}
Copy after login

代码二:

这是PHP判断手机设备函数代码,复制到PHP函数库中调用:

<&#63;php
function is_mobile() {
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$mobile_browser = Array(
"mqqbrowser", //手机QQ浏览器
"opera mobi", //手机opera
"juc","iuc",//uc浏览器
"fennec","ios","applewebKit/420","applewebkit/525","applewebkit/532","ipad","iphone","ipaq","ipod",
"iemobile", "windows ce",//windows phone
"240×320","480×640","acer","android","anywhereyougo.com","asus","audio","blackberry","blazer","coolpad" ,"dopod", "etouch", "hitachi","htc","huawei", "jbrowser", "lenovo","lg","lg-","lge-","lge", "mobi","moto","nokia","phone","samsung","sony","symbian","tablet","tianyu","wap","xda","xde","zte"
);
$is_mobile = false;
foreach ($mobile_browser as $device) {
if (stristr($user_agent, $device)) {
$is_mobile = true;
break;
}
}
return $is_mobile;
}&#63;>
Copy after login

这是调用代码,可以加上if判断:

<&#63;php if(is_mobile()):&#63;>
Copy after login

设置手机端的内容

<&#63;php endif; &#63;>
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
