edifact

Tools to process EDI messages in UN/EDIFACT format

Supported syntax is version 3.

It's provided in a Composer package:

composer require sabas/edifact

The mapping xml files are provided in a separate package:

composer require php-edifact/edifact-mapping

EDI\Parser

Given an edi message checks the syntax, outputs errors and returns the message as a multidimensional array.

INPUT

$c = new Parser($x);

Where $x could be:

• a url
• a string (wrapped message)
• an array of strings (a segment per entry)

OR

$c = new Parser();
$c->load($file);
$c->loadString($string);

OUTPUT

Errors

$c->errors();

Array

$c->get();

EDI\Encoder

Given a multidimensional array (formatted as the output of the parser), returns an EDI string, optionally one segment per line.

INPUT

$c = new Encoder($x, $wrap = true);

$x is a multidimensional array where first dimension is the EDI segment, second contains elements:

• single value
• array (representing composite elements)

$wrap is a boolean, if you need a segment per line. Set to false to disable wrapping

OR

$c = new Encoder();
$c->encode($array, $wrap);

OUTPUT

$c->get(); // returns String

EDI\Analyser

Create from EDI file readable structured text with comments from segments.xml. Requires the EDI\Mapping package.

INPUT

$mapping = new EDI\Mapping\MappingProvider('D95B');
$analyser = new EDI\Analyser();
$analyser->loadMessageXml($mapping->getMessage('CODECO'));
$analyser->loadSegmentsXml($mapping->getSegments());

• $url is the path to orginal EDI message file
• $parsed is an EDI message array created by EDI\Parser()

TEXT OUTPUT

$analyser->process($parsed); // returns text

Or

$analyser->process($parsed, $rawSegments);

• $rawSegments (optional) contains the segments in raw format from EDI\Parser::getRawSegments() to be printed before each segment in the analysed result

JSON OUTPUT Get a json representation of the array, with the element names as key.

$analyser->process($parsed);
$json = $analyser->getJson();

EDI\Reader

Read from EDI file requested segment element values.

INPUT

$r = new Reader($x);
$sender = $r->readEdiDataValue('UNB', 2);
$Dt = $r->readUNBDateTimeOfPreperation();

Where X could be:

• a url
• a string (wrapped message)
• an array of strings (a segment per entry)

OR

$c = new Parser($x);

$r = new Reader();
$r->setParsedFile($c->get());
$sender = $r->readEdiDataValue('UNB', 2);
$Dt = $r->readUNBDateTimeOfPreperation();

OUTPUT Errors

$c->errors();

Array

$c->get();

EDI\Interpreter

Organizes the data parsed by EDI/Parser using the xml description of the message and the xml segments.

INPUT

$p = new EDI\Parser($edifile);
$edi = $p->get();

$mapping = new EDI\Mapping\MappingProvider('D95B');

$analyser = new EDI\Analyser();
$segs = $analyser->loadSegmentsXml($mapping->getSegments());
$svc = $analyser->loadSegmentsXml($mapping->getServiceSegments(3));

$interpreter = new EDI\Interpreter($mapping->getMessage('CODECO'), $segs, $svc);
$prep = $interpreter->prepare($edi);

OUTPUT

Json

$interpreter->getJson()

Json for interchange service segments (UNB / UNZ)

$interpreter->getJsonServiceSegments()

Errors (per message)

$interpreter->getErrors()

Example

Edifact

DTM+7:201309200717:203'

Array

['DTM',['7','201309200717','203']]

Testing

The package should be required with composer, alongside edifact-mapping. The tests then can be run simply with phpunit in the root of the package.
