如何在另一個數組中插入關聯數組？ PHP

Question

為什么我不能在另一個數組中插入關聯數組？ 我怎樣才能做到這一點？ [PHP]

我試着得到這樣的東西：

    [0] => ['name' => 'namedperson' , 'type' => 'text' ,'id'=>'ahushaus29293' ]  
    [1] => [...] 
    ...

例子：

public function getArrayWithCustomFields($boardId, $client){
    $customFields = $client->getBoardCustomFields($boardId);
    foreach($customFields as $customField){
        array_push($array_custom_fields, array('name' => $customField->name, 'type' => $customField->type, 'id' => $customField->id));
    }
    return $array_custom_fields;
}

Answer 1

您應該初始化$array_custom_fields ，並檢查getBoardCustomFields的返回值是否是一個數組。

public function getArrayWithCustomFields($boardId, $client)
{
    // Init the array
    $array_custom_fields = [];
    $customFields = $client->getBoardCustomFields($boardId);

    // Check if the returned value from $client->getBoardCustomFields() is an array.
    if (is_array($customFields))
    {
        foreach($customFields as $customField) {
            array_push(
                $array_custom_fields,
                [
                    'name' => $customField->name,
                    'type' => $customField->type,'id' => $customField->id
                ]
            );
        }
    }

    return $array_custom_fields;
}

PS：始終在 PHP 中初始化變量是一個好習慣，即使它不會強迫您這樣做。
