PHP gets the browser type of the visitor browse page

Methods are as follows

Checks 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.

Like what:

<?php echo $_server[' http_user_agent '];? >

It is possible to print out this:

Encapsulated into functions:

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 ' in ternet 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 ')) {RET Urn ' 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 ';} Browser if (False!==strpos ($_server[' http_user_agent '), ' Micromessage ')} {return ' Micromessage ';} }
