如果在另一个平面关联数组中找到相应的键，我想更改一个多维数组中的值。
我有这两个数组：
2
1014$full = [
'Cars' => [
'Volvo' => 0,
'Mercedes' => 0,
'BMW' => 0,
'Audi' => 0
],
'Motorcycle' => [
'Ducati' => 0,
'Honda' => 0,
'Suzuki' => 0,
'KTM' => 0
]
];
$semi = [
'Volvo' => 1,
'Audi' => 1
];
我希望数组看起来像这样：
Array
(
[Cars] => Array
(
[Volvo] => 1
[Mercedes] => 0
[BMW] => 0
[Audi] => 1
)
[Motorcycle] => Array
(
[Ducati] => 0
[Honda] => 0
[Suzuki] => 0
[KTM] => 0
)
)
我从输入字段中获取 $semi 数组，并希望将其合并到 $full 中以将其保存到我的数据库中。
我已经尝试过 array_replace() 像：
$replaced = array_replace($full, $semi);

您应该循环
$semi数组并检查它是否存在于$full数组之一中，然后添加到其中：foreach ($semi as $semiItem => $semiValue) { foreach ($full as &$fullItems) { if (isset($fullItems[$semiItem])) { $fullItems[$semiItem] = $semiValue; } } }
