arrays

아래는 MapperInterface.php입니다

const에 if-else 문을 추가하는 방법을 알아 내려고합니다. 매핑 배열. 다음과 같은 것 :

if (LIN02 == “VN”)
o   Treat LIN03 as the SKU
·         else if (LIN04 == “VN”)
o   Treat LIN05 as the SKU

<?php

declare(strict_types=1);

namespace Direct\OrderUpdate\Api;

use Direct\OrderUpdate\Api\OrderUpdateInterface;

/**
 * Interface MapperInterface
 * Translates parsed edi file data to a \Direct\OrderUpdate\Api\OrderUpdateInterface
 * @package Direct\OrderUpdate\Api
 */
interface MapperInterface
{
    /**
     * Mapping array formatted as MAPPING[segemntId][elemntId] => methodNameToProcessTheValueOfElement
     * @var array
     */
    const MAPPING = [
        'DTM' => ['DTM02' => 'processCreatedAt'],   // shipment.created_at
        'PRF' => ['PRF01' => 'processIncrementId'], // order.increment_id
        'LIN' => ['LIN05' => 'processSku'],         // shipment.items.sku
        'SN1' => ['SN102' => 'processQty'],         // shipment.items.qty
        'REF' => ['REF02' => 'processTrack']        // shipment.tracks.track_number, shipment.tracks.carrier_code
    ];

    /**
     * Mapping for carrier codes
     * @var array
     */
    const CARRIER_CODES_MAPPING = ['FED' => 'fedex'];

    /**
     * @return array
     */
    public function getMapping(): array;

    /**
     * @param array $segments
     * @return OrderUpdateInterface
     */
    public function map(array $segments): OrderUpdateInterface;
}

나는 그것이 의미가 있기를 바랍니다. 더 좋은 방법이 있는지 확실하지 않지만 궁극적으로 하나 이상의 “LIN”segmentId가 필요합니다. 아마도 새로운 기능을 추가 하고이 조건을 사용합니까?
