Phase 2: Add comprehensive PHP analysis engine (lib/php-analyzer.sh)
ANALYSIS CAPABILITIES (12 functions): - Error log analysis (memory exhausted, max_children, timeouts, slow requests) - Resource usage calculations (memory per process, optimal max_children) - Traffic analysis (peak concurrent requests, avg requests/minute) - OPcache effectiveness analysis (hit rate, memory usage, recommendations) - Configuration issue detection (security, performance, capacity issues) - Complete domain analysis reporting ERROR LOG ANALYSIS: - analyze_memory_exhausted_errors: Track "Allowed memory size exhausted" - analyze_max_children_errors: Detect "server reached pm.max_children" (CRITICAL!) - analyze_slow_requests: Parse slow request logs, track slowest scripts - analyze_execution_timeout_errors: Find "Maximum execution time exceeded" RESOURCE CALCULATIONS: - calculate_memory_per_process: Average KB per PHP-FPM process - calculate_optimal_max_children: Intelligent calculation based on: * Available system memory (total - reserved) * Average memory per process * 20% safety buffer * Minimum sanity checks TRAFFIC ANALYSIS: - calculate_peak_concurrent_requests: Peak concurrent from access logs - calculate_avg_requests_per_minute: Average load over time period OPCACHE ANALYSIS: - analyze_opcache_effectiveness: Status, hit rate, memory usage, recommendations * Detects if disabled (40-70% perf loss!) * Calculates hit rate (should be >90%) * Checks wasted memory and cache capacity ISSUE DETECTION (7 critical checks): - detect_php_config_issues: Comprehensive configuration validation 1. post_max_size < upload_max_filesize (CRITICAL - uploads fail) 2. display_errors = On (HIGH - security risk) 3. memory_limit too low (MEDIUM - performance issue) 4. pm.max_children errors (CRITICAL - capacity issue) 5. Memory exhausted errors (HIGH - need more RAM or optimization) 6. OPcache disabled or low hit rate (HIGH/MEDIUM - performance) 7. pm.max_requests = 0 (MEDIUM - memory leaks accumulate) 8. pm = static on low traffic (LOW - wastes memory) COMPREHENSIVE REPORTING: - analyze_domain_php: Complete analysis report including: * PHP version detection * Configuration hierarchy (4 priority levels) * Effective settings (memory, execution, uploads) * PHP-FPM pool configuration * Resource usage (processes, memory) * OPcache status and hit rates * Traffic analysis (24h) * Error analysis (7 days) * Issues detected with severity levels * Optimization recommendations with reasoning HELPER FUNCTIONS: - convert_to_bytes: Parse human-readable sizes (128M → bytes) INTEGRATION: - Uses lib/php-detector.sh for all detection - Uses lib/system-detect.sh for system info - All functions exported for use by main optimizer NEXT PHASE: modules/performance/php-optimizer.sh (interactive menu + apply changes) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
