Insérer un tableau dans une structure multidimensionnelle

Question

J'ai une liste contenant des activity_code 的数组。我需要在项目字段中添加 pri enregistrements

communs

Array
(
    [0] => Array
        (
            [pr] => Array
                (
                    [id] => 1
                    [activity_code] => 20220101PR0001
                    [serial_number] => 0001/2022
                )
            [pri] => Array
                (
                    [item] => Item 1
                    [description] => Description 1
                    [quantity] => 15
                    [unit] => Each
                    [unit_price] => 65000.00
                )
        )

    [1] => Array
        (
            [pr] => Array
                (
                    [id] => 1
                    [activity_code] => 20220101PR0001
                    [serial_number] => 0001/2022
                )

            [pri] => Array
                (
                    [item] => Item 2
                    [description] => Description 2
                    [quantity] => 15
                    [unit] => Each
                    [unit_price] => 2500.00
                )
        )
)

items Il devrait y avoir 2 tableaux dans le champ, mais je n'ai inséré qu'un seul tableau.

Voici le code, ce que j'ai essayé.

foreach ($records as $key => $record) {
        $purchaseRequisition = $record['pr'];
        $items = $record['pri'];

        if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) {
            $purchaseArray[$purchaseRequisition['activity_code']] = [];
        }
        $purchaseArray[$purchaseRequisition['activity_code']] = [
            'serialNumber' => $record['pr']['serial_number'],
            'items' => []
        ];

        $purchaseArray[$purchaseRequisition['activity_code']]['items'][$key] = $items;
    }

C'est la structure de tableau dont j'ai besoin

Quelqu'un peut-il me dire quelle erreur je fais ici ?

Answer 1

Vous couvrez $purchaseArray[$purchaseRequisition['activity_code']]，而不是向其中推送新元素。要推入数组，请分配给 $array[].

foreach ($records as $key => $record) {
    $purchaseRequisition = $record['pr'];
    $items = $record['pri'];

    if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) {
        $purchaseArray[$purchaseRequisition['activity_code']] = [];
    }
    $purchaseArray[$purchaseRequisition['activity_code']][] = [
        'serialNumber' => $record['pr']['serial_number'],
        'items' => []
    ];

    $purchaseArray[$purchaseRequisition['activity_code']]['items'][$key] = $items;
}

Answer 2

Utilisez le code ci-dessous :

foreach ($records as $key => $record) {
        $purchaseRequisition = $record['pr'];
        $items[] = $record['pri'];

        if (!array_key_exists($purchaseRequisition['activity_code'], $purchaseArray)) {
            $purchaseArray[$purchaseRequisition['activity_code']] = [];
        
        }
        $purchaseArray[$purchaseRequisition['activity_code']] = [
            'serialNumber' => $record['pr']['serial_number'],
            'items' => []
        ];


        $purchaseArray[$purchaseRequisition['activity_code']]['items'] = $items;
        
    }
