PHP Get Browser Name Version Example Program_PHP Tutorial

To get the browser version, just use HTTP_USER_AGENT directly in php, but to specifically determine which browser and version we need to determine one by one.

Example 1

The code is as follows

Copy code

代码如下

复制代码

function get_user_browser() {  if (empty($_SERVER['HTTP_USER_AGENT'])) {   return '';  }  $agent = $_SERVER['HTTP_USER_AGENT'];  $browser = '';  $browser_ver = '';  if (preg_match('/MSIEs([^s|;]+)/i', $agent, $regs)) {   $browser = 'Internet Explorer';   $browser_ver = $regs[1];  } elseif (preg_match('/FireFox/([^s]+)/i', $agent, $regs)) {   $browser = 'FireFox';   $browser_ver = $regs[1];  } elseif (preg_match('/Maxthon/i', $agent, $regs)) {   $browser = '(Internet Explorer ' .$browser_ver.
