What are the key differences between installing PHP on a Windows server versus a UNIX server?

One key difference is the installation process itself. On a Windows server, you typically use an installer like XAMPP or WampServer to set up PHP, while on a UNIX server, you would use package managers like apt-get (for Debian-based systems) or yum (for Red Hat-based systems) to install PHP. Another difference is the configuration settings. Windows servers may have different default settings compared to UNIX servers, so you may need to adjust settings like file paths or permissions accordingly. Lastly, the way PHP interacts with the server environment may vary between Windows and UNIX. This could affect things like file paths, server variables, or even how PHP scripts are executed.

// Sample PHP code to check the server environment
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    echo 'Running on a Windows server';
} else {
    echo 'Running on a UNIX server';
}
