We have lot of script to checking browser system OS using PHP , here am going write one function using PHP
$user_agent = $_SERVER['HTTP_USER_AGENT']; function getOS() { global $user_agent; $os_platform = "Unknown OS Platform"; $os_array = array( '/windows nt 10/i' => 'Windows 10', '/windows nt 6.3/i' => 'Windows 8.1', '/windows nt 6.2/i' => 'Windows 8', '/windows nt 6.1/i' => 'Windows 7', '/windows nt 6.0/i' => 'Windows Vista', '/windows nt 5.2/i' => 'Windows Server 2003/XP x64', '/windows nt 5.1/i' => 'Windows XP', '/windows xp/i' => 'Windows XP', '/windows nt 5.0/i' => 'Windows 2000', '/windows me/i' => 'Windows ME', '/win98/i' => 'Windows 98', '/win95/i' => 'Windows 95', '/win16/i' => 'Windows 3.11', '/macintosh|mac os x/i' => 'Mac OS X', '/mac_powerpc/i' => 'Mac OS 9', '/linux/i' => 'Linux', '/ubuntu/i' => 'Ubuntu', '/iphone/i' => 'iPhone', '/ipod/i' => 'iPod', '/ipad/i' => 'iPad', '/android/i' => 'Android', '/blackberry/i' => 'BlackBerry', '/webos/i' => 'Mobile' ); foreach ($os_array as $regex => $value) if (preg_match($regex, $user_agent)) $os_platform = $value; return $os_platform; } // Get the system OS using PHP $user_os = getOS(); if($user_os == 'Windows 8') { echo "Windows 8" }
