What potential issues can arise when setting file permissions using PHP on a Windows system?

When setting file permissions using PHP on a Windows system, one potential issue that can arise is that the permissions may not be applied correctly due to differences in how Windows handles permissions compared to Unix-based systems. To solve this issue, you can use the `icacls` command in PHP to set permissions on Windows. 

// Set file permissions using icacls command on Windows
$filePath = 'C:\\path\\to\\file.txt';
$permissions = 'IIS_IUSRS:F'; // Example permission setting

exec("icacls $filePath /grant $permissions");
