Quick Start

Basic Usage

<?php
require_once 'vendor/autoload.php';

use PeanutPay\PhpEvaDts\Parser;

// Parse an EVA DTS file
$parser = new Parser();
if ($parser->load('machine_data.eva_dts')) {
    $report = $parser->getReport();
    
    // Get formatted sales report
    echo $report->generateSalesTableString();
    
    // Get structured data for analysis
    $salesData = $report->generateSalesTable();
}
?>

CLI Tool

# Generate formatted table report
php bin/sales_report.php example/animo.eva_dts

# Generate JSON output
php bin/sales_report.php --format=json example/animo.eva_dts

# Show help
php bin/sales_report.php --help

Advanced Usage with New Parser Methods

<?php
use PeanutPay\PhpEvaDts\Parser;

$parser = new Parser();
$parser->load('machine_data.eva_dts');

// Get all data tables at once
$tables = $parser->getTables();

// Individual data extraction
$salesData = $parser->getSalesData();       // Sales transactions
$productData = $parser->getProductData();   // Product information
$cashboxData = $parser->getCashboxData();   // Cash/coin management
$auditData = $parser->getAuditData();       // System audit trail
$eventData = $parser->getEventData();       // Events and errors

// Generate comprehensive reports
$salesReport = $parser->generateSalesReport();     // Sales analysis
$productReport = $parser->generateProductReport(); // Product performance
$errorReport = $parser->getErrorReport();          // Data validation

// Legacy compatibility for old templates
$legacyFormat = $parser->getProductReportLegacy();
?>

🧪 Testing and Validation

The test/ directory contains comprehensive testing and validation tools:

• test_all_reports.php - Complete parser method testing and validation
• validate_all_fields.php - EVA-DTS 6.1.2 field coverage validation
• debug_*.php - Debugging tools for specific data types
• coverage_analysis.php - Field coverage analysis and reporting

# Test all parser methods with comprehensive validation
php test/test_all_reports.php

# Validate complete field coverage
php test/validate_all_fields.php

# Run specific validation tests
php test/comprehensive_test.php

📄 Sample Data

The example/ directory contains real EVA-DTS files from various manufacturers:

• Animo coffee machines (.eva_dts format)
• Sielaff snack machines (.eva_dts format)
• Hewa combination machines (.txt format)
• ACTECH modern machines (.txt format)
• Rhevendors legacy systems (.eva_dts format)

Installation

Make sure you have Composer installed. Then, require the package in your project:

composer require peanutpay/php-evadts-parser

Usage

Here's an example of how to use the parser:

require_once __DIR__ . '/../vendor/autoload.php';

use PeanutPay\PhpEvaDts\Parser;

$parser = new Parser();

// Load an EvaDTS file
$parser->load(__DIR__ . "/rhevendors.eva_dts");

// Output the parsed report
echo $parser->getReport();

Supported Data Blocks

This parser supports all 115 documented EVA DTS 6.1.2 field identifiers with 93 specialized DataBlock classes:

Core Data Blocks (Complete Coverage)

• Product Data (PA1-PA8) - Product definitions, sales, test vends, free vends
• Price Lists (LA1) - Product pricing and sales counters
• Machine Info (ID1, ID4, ID5, ID6, MA5) - Machine identification and configuration
• Vend Counters (VA1-VA3) - Paid, test, and free vend totals

Payment Systems (All Variants)

• Coin Systems (CA1-CA24) - Complete coin management including tube levels, audit, dispensing
• Bill Systems (BA1-BA4) - Bill acceptor identification and management
• Cashless Systems (DA1-DA7) - Card payment systems, transactions, and specialty blocks

Events & Audit (Comprehensive)

• Events (EA1-EA7, EA250705) - System events, alarms, maintenance records, specialty events
• Audit Data (AM1, TA1-TA5, SA1-SA2) - Complete audit trails and time management
• Control & Status (CB1, ST, DXS, EADXS, DXE) - System status and data exchange

Extended & Device-Specific (Full Support)

• Database Blocks (DB1-DB10) - Device-specific data and configurations
• Position Data (PP1) - Product positioning information
• System Data (SD1, G85, SE, VM1) - Configuration and session management
• Specialty Blocks - All manufacturer-specific and proprietary block types

93 DataBlock classes covering 115+ unique field identifiers with full EVA DTS 6.1.2 specification compliance.

Notes

• ✅ Production Ready - Complete EVA DTS 6.1.2 specification coverage with 115+ field identifiers
• ✅ Comprehensive - 93 DataBlock classes handle data from all major vending machine manufacturers
• ✅ Extensible - Easy to add support for new or proprietary data block types
• ✅ Well Tested - Extensive test suite with real-world EVA DTS files from various machines
• ✅ Clean Architecture - Organized structure separating production code, tests, and examples
• ✅ Specialty Support - Handles unknown blocks, legacy formats, and manufacturer-specific extensions

Development and Testing

This project uses custom test scripts rather than traditional PHP testing frameworks for several reasons:

1. Domain-Specific Testing - EVA DTS parsing requires specialized validation of binary data formats
2. Real-World Data Focus - Tests use actual vending machine files rather than mocked data
3. Visual Output Requirements - Console table formatting and HTML report generation need visual validation
4. Rapid Prototyping - Custom scripts allow quick iteration during EVA DTS specification development
5. Integration Testing - End-to-end parser validation with complete data flows

The test suite in test/ provides comprehensive coverage including field validation, error handling, and format compliance testing.
