php获取访问者浏览页面的浏览器类型
方法如下
检查用户的agent字符串，它是浏览器发送的HTTP请求的一部分。用$_SERVER['HTTP_USER_AGENT']得到agent字符串信息。
比如：
| 代码如下 | 复制代码 |
|
echo$_SERVER['HTTP_USER_AGENT']; ?> |
|
有可能是打印出这样的：
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
封装成函数：
| 代码如下 | 复制代码 |
|
functionmy_get_browser(){ if(empty($_SERVER['HTTP_USER_AGENT'])){ return'robot！'; } if( (false ==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE')) && (strpos($_SERVER['HTTP_USER_AGENT'],'Trident')!==FALSE) ){ return'Internet Explorer 11.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 10.0')){ return'Internet Explorer 10.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 9.0')){ return'Internet Explorer 9.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 8.0')){ return'Internet Explorer 8.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 7.0')){ return'Internet Explorer 7.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MSIE 6.0')){ return'Internet Explorer 6.0'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Edge')){ return'Edge'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Firefox')){ return'Firefox'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Chrome')){ return'Chrome'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Safari')){ return'Safari'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'Opera')){ return'Opera'; } if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'360SE')){ return'360SE'; } //微信浏览器 if(false!==strpos($_SERVER['HTTP_USER_AGENT'],'MicroMessage')){ return'MicroMessage'; }> } |
