php-fhir

Tools for generating PHP classes from the HL7 FHIR specification.

php-fhir reads FHIR XSD schema files and produces a fully-typed PHP library complete with models, (un)serialization, validation, and a FHIR REST client — ready to drop into any PHP 8.1+ project.

Pre-generated Code

If you don't need to customise the generation process and just want usable FHIR models, grab the pre-built package: dcarbone/php-fhir-generated
