PHPAS2 is a php-based implementation of the EDIINT AS2 standard.

Open Business Objects For EDI

A strict fixed-format data parser and validator in C++20 for federal logistics records. Parses fixed-width and delimited record formats against a declarative schema, reports every violation with precise line and column positions, and refuses to silently accept malformed input — built for auditable, correctness-critical pipelines.

Fork of `libmime` to add EDI MIME functions and AS2 Support. see: branches for changes
