+# 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.
