The method is as follows

Check the user's agent string, which is part of the HTTP request sent by the browser. Use $_SERVER['HTTP_USER_AGENT'] to get the agent string information.

For example: 

<?php
 echo $_SERVER[&#39;HTTP_USER_AGENT&#39;];
?>

It may be printed like this: 

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Encapsulated into a function: 

function my_get_browser(){
 if(empty($_SERVER[&#39;HTTP_USER_AGENT&#39;])){
  return &#39;robot！&#39;;
 }
 if( (false == strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE&#39;)) && (strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;], &#39;Trident&#39;)!==FALSE) ){
  return &#39;Internet Explorer 11.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE 10.0&#39;)){
  return &#39;Internet Explorer 10.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE 9.0&#39;)){
  return &#39;Internet Explorer 9.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE 8.0&#39;)){
  return &#39;Internet Explorer 8.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE 7.0&#39;)){
  return &#39;Internet Explorer 7.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MSIE 6.0&#39;)){
  return &#39;Internet Explorer 6.0&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;Edge&#39;)){
  return &#39;Edge&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;Firefox&#39;)){
  return &#39;Firefox&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;Chrome&#39;)){
  return &#39;Chrome&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;Safari&#39;)){
  return &#39;Safari&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;Opera&#39;)){
  return &#39;Opera&#39;;
 }
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;360SE&#39;)){
  return &#39;360SE&#39;;
 }
  //微信浏览器
 if(false!==strpos($_SERVER[&#39;HTTP_USER_AGENT&#39;],&#39;MicroMessage&#39;)){
  return &#39;MicroMessage&#39;;
 }>
}
