有条件地将数组添加为另一个数组中的变量

Question

这就是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,

    )

);

我想更换以下部分

'interests' => 

    array (

    '1111111' => true,

    '2222222' => true,

    '3333333' => true,

    '4444444' => true,

    '5555555' => true,

)

$interestsAdd有了这样的变量

$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，可以在数组中定义键：$interestsAdd = [1,2,3];$dataToReset = array (    'email_address' => 'x',    'status' => 'subscribed',    'interests' => $interestsAdd);或者之后添加：$interestsAdd = [1,2,3];$dataToReset = array (    'email_address' => 'x',    'status' => 'subscribed',);$dataToReset['interests'] = $interestsAdd;或者与您当前的结构合并它们：$interestsAdd = ['interests' => [1,2,3]];$dataToReset = array_merge($dataToReset, $interestsAdd);

Answer 2

尝试像这样设置你的第一个数组：$dataToReset = [    'email_address' => $subEmail,    'status' => 'subscribed',    'interests' => [],];构建 $interestsAdd 数组后，将其添加到第一个数组：$dataToReset['interests'] = $interestsAdd;
