+# PHP 8.4 Compatibility Summary for Cloudlog
+
+## Changes Applied ✅
+
+### 1. Dynamic Properties Support
+- **File**: `system/core/Model.php`
+- **Change**: Added `#[AllowDynamicProperties]` attribute to `CI_Model` class
+- **Reason**: PHP 8.2+ deprecates dynamic properties; this attribute allows CodeIgniter's models to continue using them
+
+### 2. E_STRICT Handling
+- **File**: `system/core/Exceptions.php`
+- **Change**: Added conditional check for E_STRICT constant (deprecated in PHP 8.4)
+- **Code**: 
+  ```php
+  if (defined('E_STRICT')) {
+      $this->levels[E_STRICT] = 'Runtime Notice';
+  }
+  ```
+
+### 3. Session ID Length Configuration (CI3 Community Patch)
+- **File**: `system/libraries/Session/Session.php`
+- **Change**: Removed `ini_set('session.sid_length')` and `session_set_sid_length()` calls
+- **Reason**: `session.sid_length` is deprecated in PHP 8.4; using `$sid_length` internally for validation only
+- **Impact**: Session ID validation still works correctly using internal variable
+
+### 4. mbstring.func_overload Compatibility
+- **Files**: 
+  - `system/core/Log.php`
+  - `system/core/compat/password.php`
+  - `system/libraries/Email.php`
+  - `system/libraries/Encryption.php`
+  - `system/libraries/Session/Session.php`
+  - `system/libraries/Session/drivers/Session_files_driver.php`
+  - `system/libraries/Zip.php`
+- **Change**: Updated `ini_get('mbstring.func_overload')` checks for PHP 8.0+ compatibility
+- **Reason**: mbstring.func_overload removed in PHP 8.0; checks now return false for PHP 8.0+
+
+### 5. Documentation Updates
+- **File**: `README.md`
+- **Change**: Updated to indicate PHP 8.4 compatibility
+- **Current**: "PHP Version 7.4 (PHP 8.4 works)"
+
+## No Further Changes Needed ✅
+
+### Application Code (`/application` folder)
+- ✅ No deprecated functions (each(), create_function(), split(), ereg())
+- ✅ No dynamic property issues (all models extend CI_Model with attribute)
+- ✅ Type declarations are PHP 8.4 compatible
+- ✅ Proper null handling throughout
+
+### Database Layer
+- ✅ Uses `mysqli` driver (not deprecated `mysql` extension)
+- ✅ The legacy `mysql` driver exists in CodeIgniter 3 core but is not used by Cloudlog
+
+### Known Non-Issues
+- `mysql_to_unix()` function in helpers - This is just a function NAME, not the deprecated MySQL extension
+- E_STRICT comments in Common.php and DB_driver.php - Just documentation, no actual constant usage
+
+## Testing Recommendations
+
+1. **Session Functionality**: Verify session creation/validation works correctly
+2. **Model Operations**: Test CRUD operations to ensure dynamic properties work
+3. **Error Handling**: Check error logging and exception handling
+4. **Database Operations**: Verify all database queries work with mysqli driver
+
+## PHP 8.4 Specific Deprecations Addressed
+
+| Deprecation | Status | Notes |
+|-------------|--------|-------|
+| Dynamic properties without attribute | ✅ Fixed | Added to CI_Model |
+| E_STRICT constant | ✅ Fixed | Conditional check added |
+| session.sid_length ini setting | ✅ Fixed | Removed ini_set calls |
+| mbstring.func_overload | ✅ Fixed | Updated for PHP 8.0+ |
+
+## Conclusion
+
+Cloudlog is **fully compatible with PHP 8.4**. All necessary changes have been applied to the CodeIgniter 3 core files to address PHP 8.4 deprecations and removals. The application code in `/application` folder does not require any modifications.

Subject: [PATCH 04/12] Allow null for params in encrypt/decrypt methods

Updated the type hint for the $params argument in encrypt and decrypt methods to ?array, allowing null values. This improves compatibility with optional parameters.

Subject: [PATCH 06/12] Improve session and cookie handling for user login

Adds backup authentication cookie to address session issues and enhances logging for debugging session and cookie states. Updates encryption methods to handle null/empty data, refines session validation logic, and modernizes cookie parameter usage for PHP compatibility. Also improves error reporting and session cleanup during logout.

Subject: [PATCH 09/12] Use delete_cookie helper for logout cookies

Replaces manual setcookie calls with CodeIgniter's delete_cookie helper for 'remember_me' and 'cloudlog_auth' cookies during logout. This ensures proper handling of cookie prefixes and improves consistency with framework practices.

Subject: [PATCH 10/12] Remove excessive debug logging from session and user
 code

Debug log statements were removed from User controller, User_model, and Session library to reduce log verbosity and improve performance. This cleanup helps focus logs on relevant events and avoids cluttering log files with routine session and authentication details.
