有条件地将数组添加为另一个数组中的变量

Question

数组的最终输出应该是这样的

$dataToReset = array (
    'email_address' => $subEmail,
    'status' => 'subscribed',
    'interests' => 
        array (
        '1111111' => true,
        '2222222' => true,
        '3333333' => true,
        '4444444' => true,
        '5555555' => true,
    )
);

我想替换以下部分

'interests' => 
    array (
    '1111111' => true,
    '2222222' => true,
    '3333333' => true,
    '4444444' => true,
    '5555555' => true,
)

有了这样的变量$interestsAdd

$dataToReset = array (
    'email_address' => $subEmail,
    'status' => 'subscribed',
    $interestsAdd
);

我得到的值和我尝试过的值如下，但没有成功！

if ($form_data['lbu_multilistsvalue'] !== ''){
    
    $groupsSelected = $form_data['lbu_multilistsvalue'];
    $selectedGroups = array_fill_keys(explode(",", $groupsSelected), true);

    $interestsAdd = ['interests' => $selectedGroups];

} else {

    $interestsAdd = '';

}

Answer 1

您有多种选择，要么在数组中定义键：

$interestsAdd = [1,2,3];

$dataToReset = array (
    'email_address' => 'x',
    'status' => 'subscribed',
    'interests' => $interestsAdd
);

或之后添加：

$interestsAdd = [1,2,3];

$dataToReset = array (
    'email_address' => 'x',
    'status' => 'subscribed',
);
$dataToReset['interests'] = $interestsAdd;

或者根据您当前的结构，合并它们：

$interestsAdd = ['interests' => [1,2,3]];

$dataToReset = array_merge($dataToReset, $interestsAdd);

Answer 2

尝试像这样设置您的第一个数组：

$dataToReset = [
    'email_address' => $subEmail,
    'status' => 'subscribed',
    'interests' => [],
];

构建 $interests 添加数组后，将其添加到第一个数组：

$dataToReset['interests'] = $interestsAdd;
