Convert ZUGFeRD XML to PHP objects

This package provides an easy way to convert a ZUGFeRD-invoice.xml to a PHP object.

You can use the unpack-pdf-attachments package to unpack a ZUGFeRD-invoice.xml from a PDF.

We use both packages in our German SaaS product einfachArchiv.

Requirements

PHP 7.0 and later.

Installation

You can install this package via Composer. Run the following command:

composer require einfacharchiv/zugferd

Usage

Converting a ZUGFeRD XML is easy.

If an element is not present, the method returns null.

$xml = file_get_contents('path/to/ZUGFeRD-invoice.xml');

// Validates the XML against the ZUGFeRD XSD.
if (Validator::isValid($xml)) {
    $reader = new Reader($xml);

    // Available methods
    // Context
    $reader->getType();

    // Header
    $reader->getId();
    $reader->getName();
    $reader->getTypeCode();
    $reader->getIssueDate()->toDateTimeString();

    foreach ($reader->getNotes() as $note) {
        $note->getNote();
    }

    // Seller
    $reader->getSeller()->getName();
    $reader->getSeller()->getLineOne();
    $reader->getSeller()->getLineTwo();
    $reader->getSeller()->getZip();
    $reader->getSeller()->getCity();
    $reader->getSeller()->getCountry();

    foreach ($reader->getSeller()->getTaxNumbers() as $taxNumber) {
        $taxNumber->getNumber();
        $taxNumber->getType();
    }

    // Buyer
    $reader->getBuyer()->getId();
    $reader->getBuyer()->getName();
    $reader->getBuyer()->getLineOne();
    $reader->getBuyer()->getLineTwo();
    $reader->getBuyer()->getZip();
    $reader->getBuyer()->getCity();
    $reader->getBuyer()->getCountry();

    foreach ($reader->getBuyer()->getTaxNumbers() as $taxNumber) {
        $taxNumber->getNumber();
        $taxNumber->getType();
    }

    // Delivery
    $reader->getOccurrenceDate()->toDateTimeString();

    // Settlement
    $reader->getPaymentReference();
    $reader->getCurrency();

    foreach ($reader->getPaymentMethods() as $paymentMethod) {
        $paymentMethod->getTypeCode();
        $paymentMethod->getInformation();

        $paymentMethod->getFinancialAccount()->getIban();
        $paymentMethod->getFinancialAccount()->getName();
        $paymentMethod->getFinancialAccount()->getId();
        
        $paymentMethod->getFinancialInstitution()->getBic();
        $paymentMethod->getFinancialInstitution()->getName();
    }

    foreach ($reader->getTaxes() as $tax) {
        $tax->getTax()->getAmount();
        $tax->getTax()->getCurrency();

        $tax->getTypeCode();
        
        $tax->getBasisAmount()->getAmount();
        $tax->getBasisAmount()->getCurrency();
        
        $tax->getCategoryCode();
        $tax->getPercentage();
    }
