如何通过索引在两个数组之间合并

Question

我有两个数组..第一个数组是这样的：

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

第二个数组由 foreach 循环填充，如下所示：

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

    $count++;
}

我想合并第二个数组中的所有值以controls第一个数组中的索引

任何帮助请

Answer 1

无需合并，直接将结果放入循环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;

您还需要修复填充$controls语法，它应该是：

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