在多维数组中创建新数组,逐步命名每个循环

问题:

它正在按预期与“第1轮”合作。

<?php

// Create array skeleton.

$array_skeleton = array_fill(1, 3, "");

print_r($array_skeleton);

// Populate the skeleton with random numbers, values [1 to 6].

foreach($array_skeleton as $key => $value) {
    $populated_array[$key] = random_int(1, 6);
};

print_r($populated_array);

// Create empty array for purpose to become multidimensional array.

$scorecard = [];

// Check if [round_1] is missing, if so create [round_1] and populate it.

if(!array_key_exists("round_1", $scorecard)) {
    echo "round_1 is missing, creating it";
    $scorecard["round_1"] = $populated_array;
}

print_r($scorecard);

第一次运行脚本后,结果如预期般正常工作:

(
    [round_1] => Array
        (
            [1] => 3
            [2] => 4
            [3] => 1
        )

)

第二次运行脚本后的预期结果: 注意!正确的是,每个回合的值都是不同的,因为它们是随机创建的。

(
    [round_1] => Array
        (
            [1] => 3
            [2] => 4
            [3] => 1
        )
     [round_2] => Array
        (
            [1] => 1
            [2] => 4
            [3] => 2
        )

)
