All new teacher pages include proper access control:
```php

```

## Benefits Achieved

1. **Complete Separation**: Teachers now have their own separate pages with distinct URLs from admin pages

3. **Enhanced Security**: Teachers cannot accidentally access admin functions
4. **Improved User Experience**: Streamlined workflows designed specifically for teachers
5. **Better Maintainability**: Separate code paths for different roles make future updates easier

## Testing
All new pages have been tested to ensure:
- Proper access control (only teachers can access)
- Correct data filtering (only teacher's assigned classes/subjects)
- Functional interfaces with all features working
- Proper navigation from dashboard and sidebar
- No access to admin-specific functionality

## Files Created
1. [teachers/my_students.php](file://d:\xampp\htdocs\bidda\teachers\my_students.php) - Teacher student management
2. [teachers/marks_entry.php](file://d:\xampp\htdocs\bidda\teachers\marks_entry.php) - Teacher marks entry
3. [teachers/attendance.php](file://d:\xampp\htdocs\bidda\teachers\attendance.php) - Teacher attendance management
4. [teachers/my_reports.php](file://d:\xampp\htdocs\bidda\teachers\my_reports.php) - Teacher reports generation

## Files Updated
1. [teachers/dashboard.php](file://d:\xampp\htdocs\bidda\teachers\dashboard.php) - Quick action links
2. [includes/sidebar_layout.php](file://d:\xampp\htdocs\bidda\includes\sidebar_layout.php) - Sidebar navigation

This implementation ensures that teachers have completely separate pages from admins while maintaining all necessary functionality for their role.
