Today I published a new PHP class which generates XML for electronic invoices according to ZUGFerd / X-Factur / EN 16931 standard.

ZUGFerd / X-Factur PHP Class

The new repository at https://bitbucket.org/jwerner/php-zugferd provides a PHP class to generate the XML for a ZUGFeRD / X-Factur XML file.

The XML file represents all the data required for an electronic invoice.

The electronic invoice within this context is a PDF document which has the invoice xml embedded as a file attachment.

The generated file complies to the norm EN 16931's schema FACTUR-X_EN16931.xsd (see Example/ant validation).

The PHP class assumes invoice data to be provided as a standard PHP object. See Example/invoice.php for details.

The PHP class is adopted from the original InvoicePlane class, to reflect the new ZUGFeRD version 2.1.

Please clone, check and send me a note if you like it or find errors!
