创建多个数组并将其关联到变量，而无需进行字符串转换

Question

我一直在环顾四周，但是找不到解决我问题的方法。将我的数组与变量关联时，似乎将它们转换为字符串。

我的问题是：如何在foreach循环中创建“小”数组而不将结果数组转换为字符串。然后，如何将那些新创建的数组注入另一个“大”数组中，以期望得到如下结果：

预期$ big变量输出

[["apple", 8, "leeloo"], ["chery", 0, "leeloo"],]

当前$ big变量输出

[apple, 8, 'leeloo'],[banana, 0, 'leeloo'],

当前PHP代码

<?php

    $inputs = array(
        "apple" => 8,
        "banana" => 0
    );

    // transform inputs keys/values into arrays ("$small")
    // inject those arrays into a new array ("$big")
    $small = '';
    $big = '';
    foreach($inputs as $key => $value){
        $small .= "[$key, $value, 'leeloo'],";
    }
    $big = array($small);

    echo "small type: ", gettype($small); // string
    echo "small output: ", $small; // [apple, 8, 'leeloo'],[banana, 0, 'leeloo'],

    echo "big type: ", gettype($big); // array
    echo "big output: ", implode($big); // [apple, 8, 'leeloo'],[banana, 0, 'leeloo'],
    // expected output: [["apple", 8, "leeloo"], ["chery", 0, "leeloo"],]   

?>

最终，我的目标是让我的$ big变量表现如下：

$big = [
    ["apple", 8, "leeloo"],
    ["banana", 0, "leeloo"],
];

您可以将$big变量设置为空数组。

在循环中，使用您的值创建一个新数组，并将该数组添加到$big

$inputs = array(
    "apple" => 8,
    "banana" => 0
);
$big = [];
foreach($inputs as $key => $value){
    $big[] = [$key, $value, 'leeloo'];
}

print_r($big);

输出

Array
(
    [0] => Array
        (
            [0] => apple
            [1] => 8
            [2] => leeloo
        )

    [1] => Array
        (
            [0] => banana
            [1] => 0
            [2] => leeloo
        )
