Question

我有像下面这样的多维数组。

Array
(
    [0] => stdClass Object
        (
            [LOCATIONNAME] => test warehouse
            [CATEGORYNAME] => Fruites
            [PRODUCTNAME] => 1 - apple
            [UNITS] => 8
        )

    [1] => stdClass Object
        (
            [LOCATIONNAME] => General
            [CATEGORYNAME] => Fruites
            [PRODUCTNAME] => 10003 - Grapes
            [UNITS] => 7
        )

    [2] => stdClass Object
        (
            [LOCATIONNAME] => test warehouse
            [CATEGORYNAME] => Fruites
            [PRODUCTNAME] => 10003 - Grapes
            [UNITS] => 12
        )

    [3] => stdClass Object
        (
            [LOCATIONNAME] => General
            [CATEGORYNAME] => Standard
            [PRODUCTNAME] => 10001 - Chicken Burger
            [UNITS] => 12
        )

    [4] => stdClass Object
        (
            [LOCATIONNAME] => test warehouse
            [CATEGORYNAME] => Standard
            [PRODUCTNAME] => 10001 - Chicken Burger
            [UNITS] => 17
        )

    [5] => stdClass Object
        (
            [LOCATIONNAME] => General
            [CATEGORYNAME] => Standard
            [PRODUCTNAME] => 10002 - Sandwitch
            [UNITS] => 5
        )
)

我想用以下数组元素对上面的数组进行分组;

Array
(
    [0] => CATEGORYNAME
    [1] => PRODUCTNAME
)

我希望将第一个数组与第二个数组元素进行汇总并总结（例如，总结每个仓库的数量）。我已经这样做但我不能按类别汇总元素

我想打印这个数组如下 click to view

是否可以将数组与其他数组元素组合在一起。如果你可以帮助我，那就太棒了。

确定。根据您的要求，我假设您需要以下格式：

$result = array(
    'Standard' => array(
        '10001 - Chicken Burger' => array(
            array(
                'LOCATIONNAME' => 'General',
                'UNITS' => 5
            ),
            array(
                'LOCATIONNAME' => 'test warehouse',
                'UNITS' => 17
            ),
        ),
        '10002 - Sandwitch' => array(
            array(
                'LOCATIONNAME' => 'General',
                'UNITS' => 5
            )
        )
    )
);

为此，代码将是：

$result = array();
foreach ($objects as $obj) {
    if (!is_array($result[$obj->CATEGORYNAME])) {
        $result[$obj->CATEGORYNAME] = array();
    }

    if (!is_array($result[$obj->CATEGORYNAME][$obj->PRODUCTNAME])) {
        $result[$obj->CATEGORYNAME][$obj->PRODUCTNAME] = array();
    }

    $temp = array(
        'LOCATIONNAME' => $obj->LOCATIONNAME,
        'UNITS' => $obj->UNITS
    );

    array_push($result[$obj->CATEGORYNAME][$obj->PRODUCTNAME], $temp);
}

所以根据上面的输出，您可以按如下方式打印表格：

<?php

$result = array(
    'Standard' => array(
        '10001 - Chicken Burger' => array(
            array(
                'LOCATIONNAME' => 'General',
                'UNITS' => 5
            ),
            array(
                'LOCATIONNAME' => 'test warehouse',
                'UNITS' => 17
            ),
        ),
        '10002 - Sandwitch' => array(
            array(
                'LOCATIONNAME' => 'General',
                'UNITS' => 5
            )
        )
    )
);

?>

<html>
    <head>
        <title>Test Table</title>

    <table class="table table-bordered">

            <tr>
                <th>Location</th>
                <th>Units</th>
            </tr>
        </thead>
        <tbody>
            <?php foreach ($result as $category => $catDetails) { ?>
            <tr>
                <td colspan="2"><?php echo $category; ?></td>
            </tr>
            <?php foreach ($catDetails as $product => $items) { ?>
            <tr>
                <td colspan="2"><?php echo $product; ?></td>
            </tr>
            <?php foreach ($items as $item) { ?>
            <tr>
                <td><?php echo $item['LOCATIONNAME']; ?></td>
                <td><?php echo $item['UNITS']; ?></td>
            </tr>
            <?php } } } ?>
        </tbody>
    </table>
</body>

希望这有帮助。
