Question

我有以下数组：

$dish = [
    'fr' => [
            ['lunch','starter','dish name fr 1','dish info 1','price 1'],
            ['lunch','starter','dish name fr 2','dish info 2','price 2'],
            ['both','starter','dish name fr 3','dish info 3','price 3'],
            ['both','main','dish name fr 4','dish info 4','price 4'],
            ['both','main','dish name fr 5','dish info 5','price 5'],
            ['both','main','dish name fr 6','dish info 6','price 6'],
            ['both','dessert','dish name fr 7','dish info 7','price 7'],
            ['diner','dessert','dish name fr 8','dish info 8','price 8'],
            ],
    'nl' => [
            ['lunch','starter','dish name nl 1','dish info 1','price 1'],
            ['lunch','starter','dish name nl 2','dish info 2','price 2'],
            ['both','starter','dish name nl 3','dish info 3','price 3'],
            ['both','main','dish name nl 4','dish info 4','price 4'],
            ['both','main','dish name nl 5','dish info 5','price 5'],
            ['both','main','dish name nl 6','dish info 6','price 6'],
            ['both','dessert','dish name nl 7','dish info 7','price 7'],
            ['diner','dessert','dish name nl 8','dish info 8','price 8'],
            ],
    'en' => [
            ['lunch','starter','dish name en 1','dish info 1','price 1'],
            ['lunch','starter','dish name en 2','dish info 2','price 2'],
            ['both','starter','dish name en 3','dish info 3','price 3'],
            ['both','main','dish name en 4','dish info 4','price 4'],
            ['both','main','dish name en 5','dish info 5','price 5'],
            ['both','main','dish name en 6','dish info 6','price 6'],
            ['both','dessert','dish name en 7','dish info 7','price 7'],
            ['diner','dessert','dish name en 8','dish info 8','price 8'],
            ],
];

与

foreach ($dish[$lang] as list($a, $b, $dish_name, $dish_info, $price)) {  
echo $dish_name 
; }

我设法通过语言：

菜名fr 1

菜名fr 2

菜名fr 3

菜名nl 1

菜名nl 2

菜名nl 3

菜名en 1

菜名en 2

菜名en 3

但我也想通过菜肴来展示：

初学者

菜名fr 1

菜名nl 1

菜名en 1

菜名fr 2

菜名nl 2

菜名en 2

菜名fr 3

菜名nl 3

菜名en 3

主要

菜名fr 4

菜名nl 4

菜名en 4

菜名fr 5

菜名nl 5

菜名en 5

菜名fr 3

菜名nl 3

菜名en 3

你会怎么做？

谢谢

Answer 1

我会正确地将它重建为另一个数组：

$newArr = array();

$i = 0;
foreach($dish AS $langString => $lang){
    foreach($lang AS $key => $subdish){
        $newArr[$subdish[1]][$i]['dish'] = $subdish[2];
        $newArr[$subdish[1]][$i]['sort'] = $key;
        $i++;
    }
}

function sortByOrder($a, $b) {
    return $a['sort'] - $b['sort'];
}

usort($newArr['starter'], 'sortByOrder');
usort($newArr['main'], 'sortByOrder');
usort($newArr['dessert'], 'sortByOrder');

foreach($newArr as $course => $food){

    echo '<h2>' . $course .'</h2>';
    foreach($food as $plate){
        echo $plate['dish'] . '<br />';
    }
}

请记住，它可以更聪明，更有效地完成，这纯粹是为了给你一个＆＃39;了解如何实现这样的目标。

此外，您必须找到一种方法来对新阵列中的菜肴进行分类，以便按照您的方式进行排序。

添加了排序功能，是的，有很多代码可以说是简单的，但这是我当时可以酿造的，并且数据结构可用。
