How Can I Get the User's Operating System Information Using PHP?

Get operating system info

A common question for PHP based applications is "how to get user os info." This can be useful for showing customized content or providing a better user experience. In this article, we will look at how to get the operating system information from the user's browser using PHP.

We can use the $_SERVER['HTTP_USER_AGENT'] variable to get the user's browser information. This variable contains a string that identifies the user's browser and operating system.

We can use a regular expression to extract the operating system information from the $_SERVER['HTTP_USER_AGENT'] string. Here is an example of a regular expression that can be used to extract the operating system information:

$regex = '/(Windows NT 10\.0)|(Windows NT 6\.3)|(Windows NT 6\.2)|(Windows NT 6\.1)|(Windows NT 6\.0)|(Windows NT 5\.2)|(Windows NT 5\.1)|(Windows XP)|(Windows NT 5\.0)|(Windows ME)|(Win98)|(Win95)|(Win16)|(Mac OS X 10\_[0-9]+(\.[0-9]+)?(\.[0-9]+)?)|(Mac OS X)|(Mac_PowerPC)|(Linux)|(Ubuntu)|(iPhone)|(iPod)|(iPad)|(Android)|(BlackBerry)|(WebOS)/';
$os_platform = preg_match($regex, $_SERVER['HTTP_USER_AGENT'], $matches) ? $matches[0] : 'Unknown OS Platform';

Here's an example of how you might use this code to get the user's operating system information:

$os_platform = getOS();
echo "Your operating system is $os_platform";

This code will print the user's operating system information to the screen.
