php gets the browser type of the visitor browsing the page

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:

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($_SERVER['HTTP_USER_AGENT'])){
  return 'robot！';
 }
 if( (false == strpos($_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';
 }>
}
