What potential pitfalls should be aware of when installing PHP on a Windows system?

One potential pitfall when installing PHP on a Windows system is ensuring that the correct version of PHP is compatible with the Windows operating system. Additionally, configuring the PHP settings correctly in the php.ini file is crucial to avoid any compatibility issues. It is also important to set up the environment variables properly to ensure that PHP can be accessed from the command line.

// Example PHP code snippet to fix environment variables issue on Windows
// Add PHP installation directory to the PATH environment variable
$phpDir = 'C:\path\to\php';
putenv("PATH=" . $phpDir . PATH_SEPARATOR . getenv("PATH"));
