PHP foreach多維數組

Question

我有一個像這樣的多維數組：

Array
(
    [Category1] => Array
        (
            [1] => Array
                (
                    [0] => Img 1
                    [1] => Title 1
                    [2] => Text 1
                )

            [5] => Array
                (
                    [0] => Img 17
                    [1] => Title 17
                    [2] => Text 5
                )

            [10] => Array
                (
                    [0] => Img 1
                    [1] => Title 6
                    [2] => Text 10
                )

            [16] => Array
                (
                    [0] => Img 16
                    [1] => Title 12
                    [2] => Text 16

                )

            [13] => Array

                    [0] => Img 13
                    [1] => Title 9
                    [2] => Text 13
                )

        )

    [Category3] => Array
        (
            [3] => Array
                (
                    [0] => Img 3
                    [1] => Title 3
                    [2] => Text 3
                )

            [7] => Array
                (
                    [0] => Img 19
                    [1] => Title 19

                )

            [15] => Array

                    [0] => Img 15
                    [1] => Title 11

                    [2] => Text 12
                )

        )

)

我需要幫助來查看這樣的內容，$ myarray就像最上面的例子一樣。 在firs foreach所有它都沒關系，但在第二和第三foreach如果我在一個類別有一個以上的數組，它被公開並顯示不是corectly。

<div id="tab-container">
        <ul>
            <?php foreach ($myarray as $category => $detail) { ?>
                <li><a href="#tab-<?=$category?>"><?=$category?></a></li>
            <?php }; ?>
        </ul>

    <div>
        <?php foreach (??? ??? ???) { ?>
            <div id="tab-<?=$category?> for ex Category 1 contain Array (1, 5 10, 16)">
                <div class="tab-content_left">
                    <div><img src="<?=base_url();?>img/$value[0] for ex Img 1" /></div>
                    <div>$value[1] for ex Title 1</div>
                    <div>$value[2] for ex Text 1</div>
                </div>

                <div class="tab-content_right">
                    <?php foreach (??? ??? ???) { ?>
                        <div><img src="<?=base_url();?>img/"$value[0] for ex Img 17 /></div>
                        <div>$value[1] for ex. Title 17</div>
                        <div>$value[2] for ex Text 5</div>
                    <?php }; ?>
                </div>
            </div>
        <?php }; ?>
    </div>
</div>

謝謝。 請一些想法我怎么能把foreach cicles和哪里？

Answer 1

第一個foreach：

<?php foreach ($mainArray as $categoryKey => $singleCategory) { ?>

第二個foreach：

<?php foreach ($singleCategory as $categoryEntry) { ?>

注意：

要獲取類別名稱，請在第一個foreach中寫入$categoryKey 。 要獲取數據： $singleCategory['image']在第二個foreach中。

檢查foreach文檔。
