<?php
function getBrowser(){
$agent=$_SERVER["HTTP_USER_AGENT"];
if(strpos($agent,'MSIE')!==false || strpos($agent,'rv:11.0')) //ie11判断
return "ie";
else if(strpos($agent,'Firefox')!==false)//火狐
return "firefox";
else if(strpos($agent,'Chrome')!==false)//谷歌
return "chrome";
else if(strpos($agent,'Opera')!==false)//opera
return 'opera';
else if((strpos($agent,'Chrome')==false)&&strpos($agent,'Safari')!==false)
return 'safari';
}
function getBrowserVer(){
if (empty($_SERVER['HTTP_USER_AGENT'])){ //当浏览器没有发送访问者的信息的时候
return 'unknow';
}
$agent= $_SERVER['HTTP_USER_AGENT'];
if (preg_match('/MSIE\s(\d+)\..*/i', $agent, $regs))//IE浏览器版本号
return $regs[1];
elseif (preg_match('/FireFox\/(\d+)\..*/i', $agent, $regs))//火狐浏览器版本号return $regs[1];
elseif (preg_match('/Opera[\s|\/](\d+)\..*/i', $agent, $regs))//opera浏览器版本号
return $regs[1];
elseif (preg_match('/Chrome\/(\d+)\..*/i', $agent, $regs))//谷歌浏览器版本号
return $regs[1];
elseif ((strpos($agent,'Chrome')==false)&&preg_match('/Safari\/(\d+)\..*$/i', $agent, $regs))
return $regs[1];
else
return 'unknow';
}
$a=(getBrowser());
$b=(getBrowserVer());
echo $a;//然后对变量进行判断等操作
echo $b;
?>The above introduces php to get the browser kernel version, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
