Configuration

Environment Variables (.env)

The application uses a .env file for all sensitive configuration. This file is never committed to git.

Database Configuration:

DB_HOST=localhost          # Database server
DB_NAME=payroll           # Database name
DB_USER=payroll_user      # Database username
DB_PASS=strong_password   # Database password (16+ chars)
DB_CHARSET=utf8mb4        # Character set

Application Configuration:

APP_NAME="Your Company Payroll"
APP_URL=https://yourdomain.com
APP_ENV=production        # production, development, or staging
DEBUG_MODE=false          # MUST be false in production
SESSION_NAME=pay          # PHP session name
TIMEZONE=America/Anchorage

See ENV_SETUP.md for detailed environment configuration guide.

Security Settings

Production Settings (Automatic when APP_ENV=production):

✅ Session cookies: HttpOnly, Secure, SameSite=Strict
✅ Session ID regeneration on login
✅ Error display: OFF (errors logged only)
✅ HTTPS-only cookies
✅ Strict session mode

Debug Mode:

DEBUG_MODE=true - Shows detailed errors (development only)
DEBUG_MODE=false - Hides errors, logs only (production required)

Usage

First Time Setup

Login as Admin
- URL: https://yourdomain.com/login.php
- Default credentials: admin / admin
- IMMEDIATELY change password in Admin Account
Configure Company Settings
- Navigate to: Settings → Company Setup
- Enter company information
- Set employee count for Alaska sick leave cap
- Configure Alaska unemployment rate
- Select color theme
Set Up Employees
- Navigate to: Employees → Employee Setup
- Add all employees with pay rates and tax info
- Configure Alaska fields for quarterly reporting

Processing Payroll

Navigate to: Payroll → Payroll Input
Select employee from dropdown
Enter hours worked:
- Regular hours (e.g., 80 for bi-weekly)
- Overtime hours (paid at 1.5x)
- Sick hours used (deducted from balance)
- Vacation hours used (deducted from balance)
System automatically calculates:
- Sick leave accrued (1 hr per 30 worked)
- Vacation accrued (annual / 26 periods)
- Federal tax withholding
- FICA & Medicare taxes
- Net pay
Click "Record Payment"

Viewing Reports

Payment Records:

Payroll → Records → Select Employee

Paystubs:

Click "View Paystub" from records
Shows all deductions and leave balances

Tax Reports:

Tax & Reports → Tax Payment Report (monthly/quarterly employer taxes)
Tax & Reports → IRS Form 941 (quarterly federal tax return)

Alaska Sick Leave Compliance

Automatic Accrual:

1 hour sick leave per 30 hours worked
Accrues each pay period automatically
Subject to annual caps

Annual Caps (configured in Company Settings):

15+ employees: 56 hours/year maximum
<15 employees: 40 hours/year maximum

Year-End Handling:

January 1st: YTD counters reset to zero
Balance carries over to new year
Can accrue up to annual cap again

Example:

Employee works 80 hours
Sick leave accrued: 80 ÷ 30 = 2.67 hours
If at cap (40 hrs), no additional accrual
Balance visible on paystub

Alaska Quarterly Wage Reports

Required Quarterly (Due end of month following quarter):

Navigate to: Tax & Reports → Alaska CSV Export
Enter Alaska Employer Account Number
Select year and quarter (1-4)
Click "Generate CSV File"
Review validation warnings
Download CSV file
Upload to Alaska UI Tax & Wage System

Before Generating:

Ensure employees have: SSN, Occupation Code (SOC), Geographic Code
Set these in Employee Setup → Edit Employee
Verify Alaska Employer Account in Company Setup

Security Features

Authentication & Authorization

✅ Centralized Auth: All controllers use requireAdmin(), requireEmployee(), or requireAuth() ✅ Session Management: Secure session handling with production hardening ✅ Password Hashing: MD5+SHA1 for legacy compatibility (recommend bcrypt upgrade) ✅ Access Control: Role-based access (admin vs employee)

SQL Injection Prevention

✅ PDO Prepared Statements: 100% of database queries use parameterized statements ✅ No String Concatenation: Zero SQL queries with variable concatenation ✅ Input Validation: All user input validated before processing

XSS Protection

✅ Output Escaping: htmlspecialchars() on all user-generated content ✅ Input Sanitization: User input cleaned before storage ✅ Safe HTML: Controlled HTML generation in controllers

Session Security (Production)

✅ HttpOnly Cookies: Prevents JavaScript access to session cookies ✅ Secure Cookies: Cookies only sent over HTTPS ✅ SameSite: CSRF protection via SameSite=Strict ✅ Session Regeneration: New session ID after login ✅ Strict Mode: Rejects uninitialized session IDs

Environment Security

✅ Credentials in .env: Never hardcoded in code ✅ .gitignore Protection: .env file never committed to git ✅ Config Separation: config/config.php contains no secrets ✅ Error Logging: Production errors logged, never displayed

File Security

✅ 600 Permissions on .env: Readable only by web server ✅ 644 on PHP Files: Secure but readable permissions ✅ 755 on Directories: Proper directory permissions ✅ .htaccess Protection: Blocks access to sensitive files

Troubleshooting

Common Issues

Database Connection Error

Solution:
1. Check .env file exists and has correct credentials
2. Verify MySQL is running: sudo systemctl status mysql
3. Test connection: mysql -u username -p database_name
4. Check DB_HOST, DB_NAME, DB_USER, DB_PASS in .env

"Class not found" Error

Solution:
1. Ensure bootstrap.php is included in route files
2. Verify PSR-4 autoloader is registered in bootstrap.php
3. Check class namespace matches directory structure
4. Clear any PHP opcode cache

Session Errors in Production

Solution:
1. Verify APP_ENV=production in .env
2. Ensure HTTPS is configured (required for secure cookies)
3. Check session directory is writable
4. Review error logs for specific session errors

"Undefined array key" Errors

Solution:
1. Run all database migrations:
   - update_alaska_sick_leave.sql
   - update_alaska_csv_fields.sql
2. Verify all required columns exist in tables
3. Check IMPLEMENTATION_GUIDE.md for migration steps

Tax Calculations Incorrect

Solution:
1. Verify federal_tax_brackets table has 2025 data
2. Check payroll_taxes table for current rates
3. Verify employee filing_status is set
4. Check W-4 withholding_allowances value

Alaska CSV Export Fails

Solution:
1. Set Alaska Employer Account in Company Setup
2. Ensure employees have: SSN, occupation_code, geographic_code
3. Verify downloads/ directory exists and is writable (755)
