如何通過索引在兩個數組之間合並

Question

我有兩個數組..第一個數組是這樣的：

$questions = [
    "type" => "form",
    "controls" => []
];

第二個數組由 foreach 循環填充，如下所示：

$count = 0;
foreach($x as $y){
    $controls [
        "id" => $y.$count,
        "id2" => $y.$count+1,
    ]

    $count++;
}

我想合並第二個數組中的所有值以controls第一個數組中的索引

任何幫助請

Answer 1

無需合並，直接將結果放入循環中你想要的位置即可

$questions = [
        "type" => "form",
        "controls" => []
    ];   

$count = 0;
foreach($x as $y){
    $questions['controls'][] =  ["id" => $y.$count,
                                 "id2" => $y.$count+1];
    $count++;
}

Answer 2

做就是了：

$questions['controls'] = $controls;

您還需要修復填充$controls語法，它應該是：

$controls[] = [
    "id" => $y.$count,
    "id2" => $y.$count+1,
];
