php基于http协议访问,判断访问来源iphone,android,微信浏览器,pc电脑

当我们采用php作为服务数据端口,为移动端,pc端提供数据接口的时候,可能会要求记录接口访问的来源是来之哪里.

例如:生成订单,可能就需要记录,以便做一些数据分析,为运营和推广提供一些数据支持.

现在移动终端是太多的了,所以你也不得不做出这么多的判断的了。看下这些移动终端的判断吧:

function order_source()  
{  
    $useragent  = strtolower($_SERVER["HTTP_USER_AGENT"]);  
    // iphone  
    $is_iphone  = strripos($useragent,'iphone');  
    if($is_iphone){  
        return 'iphone';  
    }  
    // android  
    $is_android    = strripos($useragent,'android');  
    if($is_android){  
        return 'android';  
    }  
    // 微信  
    $is_weixin  = strripos($useragent,'micromessenger');  
    if($is_weixin){  
        return 'weixin';  
    }  
    // ipad  
    $is_ipad    = strripos($useragent,'ipad');  
    if($is_ipad){  
        return 'ipad';  
    }  
    // ipod  
    $is_ipod    = strripos($useragent,'ipod');  
    if($is_ipod){  
        return 'ipod';  
    }  
    // pc电脑  
    $is_pc = strripos($useragent,'windows nt');  
    if($is_pc){  
        return 'pc';  
    }  
    return 'other';  
}  
Copy after login

 

根据自己的需求 ,来做一些特殊处理比如区分浏览器,这里就不做介绍了.

自己 echo $_SERVER["HTTP_USER_AGENT"] 出来看一下就明了.

如果判断是不是属于微信浏览器,在IOS系统和ANDROID下都通用的就是判断HTTP_USER_AGENT中是否带有:micromessenger 

 

$res = strripos($str,$findstr) 此方法是在 $str 字符串中匹配 $findstr 最后一次出现的位置,匹配不到返回 false ,

也就是说假如匹配的字符串在首位出现就会返回0,那么 if($res){...} 就无法正确返回,

比较正确的写法应该是 if($res === 0 || $res > 0){...} ,(3个等于号是不仅是值相等还要数据类型相等),

当然我们已经知道哪些关键字是不会出现在首位,所以上面那种写法就可以了.

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,
