In PHP programming, we often need to determine the type of operating system on the current server, especially when performing cross-platform development or debugging. Knowing the operating system type is essential. PHP provides a very useful function, php_uname(), which returns detailed information about the current operating system. By combining it with the strpos() function, we can easily determine the system type, whether it's Linux, Windows, or macOS.

The stripos() function is used to find the first occurrence of a string within another string in a case-insensitive manner.
