||||
```bash
|
||||
detect_php_pools() # Find all FPM pool configs
|
||||
get_php_config_hierarchy() # Map .user.ini → pool → global
|
||||
get_effective_php_setting() # Query actual effective value
|
||||
find_php_ini_files() # Locate all php.ini files
|
||||
detect_php_version_per_domain() # ea-php80, ea-php82, etc.
|
||||
```
|
||||
|
||||
### Phase 2: PHP Analyzer Library (Priority: HIGH)

|
||||
analyze_fpm_logs() # Parse error logs for max_children errors
|
||||
calculate_optimal_max_children() # Memory + traffic based
|
||||
calculate_memory_per_process() # ps aux analysis
|
||||
check_opcache_status() # Hit rate, memory usage
|
||||
detect_php_issues() # Comprehensive issue detection

|
||||
```
|
||||
|
||||

|
||||
- Issue detection and recommendations
|
||||
- One-click apply with backups
|
||||

|
||||
|
||||
### Phase 4: Integration (Priority: MEDIUM)

|
||||
|
||||
## Issues Fixed This Session
|
||||
|
||||
### Critical Bugs (Would Have Prevented Functionality)
|
||||

|
||||
2. **enable-cphulk.sh couldn't import** - Wrong API function used
|
||||
3. **IP blocking failing** - is_valid_ip function missing
|
||||
4. **Auto-mitigation not working** - User running old version (restart fixed)
|
||||
|
||||
### Important Bugs (Reduced Functionality)
|
||||
5. **SSH attacks not showing** - ATTACK_TYPE_COUNTER not updated
|
||||
6. **Colors not rendering** - echo without -e flag
|
||||
7. **save_snapshot errors** - Function not implemented
|
||||
|
||||
### Performance Issues
|
||||
8. **23 subprocess calls** - Replaced with bash built-ins
