Question

我有2个阵列，一个充满了横向图像网址，另一个充满了纵向图像网址。它们最终将在图像幻灯片放映的页面上输出，每张幻灯片由4个风景图像和2个肖像图像组成。

我已将图像放入阵列中，我称之为

$horizontalImages
$verticalImages

现在我想创建一个新数组，从$horizontalImages中选择前4个图像，从$verticalImages中选择前2个图像，并在新数组中创建一个条目。然后递归地选择$horizontalImages中的下一个4和$verticalImages中的下一个2，并在新数组中生成下一个项目并继续，直到没有更多项目为止。

所以，我认为数据看起来像天空的例子就像下面这样，请原谅我的错误，我可以根据看起来的样子来解决这个问题，我可以＆甚至可以判断这是否正确或是否是多维/嵌套数组，所以我需要帮助理解这个新数组结构的原理。

array(x) {
    [0]=>???Array???(x){
       [0]=>"/landscape-image-1.jpg"
       [1]=>"/landscape-image-2.jpg"
       [2]=>"/landscape-image-3.jpg"
       [3]=>"/landscape-image-4.jpg"
       [4]=>"/portrait-image-1.jpg"
       [5]=>"/portrait-image-2.jpg"
    }
    [1]=>???Array???(x){
       [0]=>"/landscape-image-5.jpg"
       [1]=>"/landscape-image-6.jpg"
       [2]=>"/landscape-image-7.jpg"
       [3]=>"/landscape-image-8.jpg"
       [4]=>"/portrait-image-3.jpg"
       [5]=>"/portrait-image-4.jpg"
    }
}

一旦我以一种真正有效的方式锁定阵列，我想通过foreach循环将其放入：

foreach ($myArray as $slide):
$image1 = $slide['0'];
$image2 = $slide['1'];
$image3 = $slide['2'];
$image4 = $slide['3'];
$image5 = $slide['4'];
$image6 = $slide['5'];

// Blah blah HTML output, so on so forth...

endforeach;

我希望我提供了足够的信息。在此提前感谢您的任何帮助。

这是我尝试的东西，似乎有点工作......但我得到了重复等等。

$countH = 0;
$countV = 0;

foreach ($horizontalImages as $key => $horizImg):

    $countH++;

       foreach ($verticalImages as $k =>$vertImg):

                    $countV++;

                    if ($countH % 4 == 1):

             $variables[$countH][] = $horizImg; 

                            if ($countV % 2 == 1):
                                $variables[$countH][] = $vertImg; 
                            endif;

                    endif;

       endforeach;
    endforeach;



    <pre>
    <?php var_dump($variables); ?>
    </pre>

结果

Answer 1

$ch = ceil(count($horizontalImages) / 4);// Count of quartet (including incomplete tuples)
$cv = ceil(count($verticalImages) / 2);// Count of doublet (including incomplete tuples)

$c = $ch>$cv ? $ch : $cv; // Are there more - quartets or doublets?    
$out = array();

// We pass on the long side
for ($x=0;$x<$c;$x++) {
    $tmp1 = $x<$ch ? array_slice($horizontalImages, $x*4, 4) : array(); // No more quartet?
    $tmp2 = $x<$cv ? array_slice($verticalImages, $x*2, 2) : array(); // No more doublet?
    $out[] = array_merge( $tmp1, $tmp2 ); // Fold tuples together
}
