Parse, build, serialize and validate UN/EDIFACT Messages in a memory efficient way.

You will likely have to generate your own Segments, see php-edifact/edifact-mapping for XML Mappings. I have done a protype for autogeneration, it should give you a good starting point.

If you don't need validation or Segment getter you can also parse to the generic Segment.

Usage

Parse EDIFACT Messages

Load Segment Classes

You can add your Segments to the Factory like so:

use Apfelfrisch\Edifact\Segment\SegmentFactory;

$segmentFactory = new SegmentFactory;
$segmentFactory->addSegment('SEQ', \My\Namespace\Segments\Seq::class);

After that you can either mark the Factory as default:

$segmentFactory->markAsDefault();

or you inject the Factory in the Message:

use Apfelfrisch\Edifact\Segment\SegmentFactory;

$message = Message::fromString("UNA:+.? 'SEQ+1", $segmentFactory);

If you don't need validation or Segment getter you can also parse to the generic Segement

use Apfelfrisch\Edifact\Segments\Generic;
use Apfelfrisch\Edifact\Segment\SegmentFactory;

$segmentFactory = new SegmentFactory;
$segmentFactory->addFallback(Generic::class);
$segmentFactory->markAsDefault();

Parse from String

use Apfelfrisch\Edifact\Message;

$message = Message::fromString("UNA:+.? 'NAD+DP++++Musterstr.::10+City++12345+DE");

Parse from File

use Apfelfrisch\Edifact\Message;

$message = Message::fromFilepath('path/to/file.txt');

Iterate over Segments

use Apfelfrisch\Edifact\Segments\SegmentInterface;

foreach ($message->getSegments() as $segment) {
    if ($segment instanceof SegmentInterface) {
        echo $segment->name();
    }
}

Filter Segments

use My\Namespace\Segments\MyNad;

foreach ($message->filterSegments(MyNad::class) as $segment) {
    echo $segment->name(); // NAD
}

$message->filterSegments(MyNad::class, fn(Nad $seg): bool 
    => $seg->street() === 'Musterstr.'
);

echo $message->findFirstSegment(MyNad::class)->name(); // NAD

Unwrap Messages

foreach ($message->unwrap() as $partialMessage) {
    echo $segment instanceof \Apfelfrisch\Edifact\Message;
}

Add Readfilter

$message->addStreamFilter('iso-to-utf8', 'convert.iconv.ISO-8859-1.UTF-8');

Build a Message:

Build with default Una

use Apfelfrisch\Edifact\Builder;
use Apfelfrisch\Edifact\Message;
use My\Namespace\Segments\MyUnb;
use My\Namespace\Segments\MyUnh;

$builder = new Builder;

$builder->writeSegments(
    MyUnb::fromAttributes('1', '2', 'sender', '500', 'receiver', '400', new DateTime('2021-01-01 12:01:01'), 'unb-ref'),
    MyUnh::fromAttributes('unh-ref', 'type', 'v-no', 'r-no', 'o-no', 'o-co')
);

$message = new Message($builder->get());

UNA and the trailing Segments (UNT and UNZ) will be added automatically. If no UNA Segment is provided, it uses the default values [UNA:+.? '].

Build with custom Una

use Apfelfrisch\Edifact\Builder;
use Apfelfrisch\Edifact\Segment\UnaSegment;

$builder = new Builder(new UnaSegment('|', '#', ',', '!', '_', '"'));

If you replace the decimal seperator, be sure that the blueprint marks the value as numeric.

Write directly into File

use Apfelfrisch\Edifact\Builder;
use Apfelfrisch\Edifact\Segment\UnaSegment;

$builder = new Builder(new UnaSegment, 'path/to/file.txt');

Add Writefilter to the Builder

use Apfelfrisch\Edifact\Builder;

$builder = new Builder;
$builder->addStreamFilter('utf8-to-iso', 'convert.iconv.UTF-8.ISO-8859-1');

Validate Message Segments

use Apfelfrisch\Edifact\Message;
use Apfelfrisch\Edifact\Validation\Failure;
use Apfelfrisch\Edifact\Validation\Validator;

$message = Message::fromString("UNA:+.? 'SEQ+9999", $segmentFactory);

$validator = new Validator;

if(! $validator->isValid($message)) {
    foreach ($validator->getFailures() as $failure) {
        echo $failure instanceof Failure;
    }
}
