What are common permission issues that PHP developers may encounter when uploading files on a Windows server?

Common permission issues that PHP developers may encounter when uploading files on a Windows server include insufficient permissions to write to the upload directory or incorrect ownership settings. To solve this, you can adjust the permissions of the upload directory to allow the PHP process to write to it.

// Set the correct permissions for the upload directory
$uploadDir = 'uploads/';
chmod($uploadDir, 0777);
