Я работаю над приложением, в котором я создаю JSON, используя PHP. Мой код здесь.PHP json_encode производит неправильные результаты JSON. Зачем?
$arrayItem = array_slice($data, $start, $max);
$jsonArray = array();
$jsonArray['total'] = count($arrayItem);
for ($i = 0; $i <= 9; $i ++) {
// Listomatic requires the "total" field to show/hide the "Show More" button
// The following is sample data (in this case Powerball numbers) that you want to display
$item = array(
'id' => $arrayItem[$i]['id'],
'title' => $arrayItem[$i]['title'],
'featured_image' => $arrayItem[$i]['featured_image'],
'audio_file' => $arrayItem[$i]['audio_file'],
'youtube_id' => $arrayItem[$i]['youtube_id'],
'open_par' => $arrayItem[$i]['open_par'],
'category' => $arrayItem[$i]['category']);
$list_array[] = array('item' =>$item);
}
$jsonArray['items'] = $list_array;
header('Content-type: application/json');
echo json_encode($jsonArray);
Он производит следующие JSON. Я не уверен, почему добавляются нули.

Хотя мне нужен следующий JSON для вывода.
{

"featured_image": "http://www.christianquestions.net/wp-content/uploads/2004/05/cq_small_logo-310x227.jpg",

"open_par": "",
"category": "Social Issues"
}
},
{
"item": {
"id": "233",
"title":"Do You Use the Spirit of a Sound Mind?",
"featured_image": "http://www.christianquestions.net/wp-content/uploads/2004/05/cq_small_logo-310x227.jpg",

}
},
{
"item": {

"featured_image": "http://www.christianquestions.net/wp-content/uploads/2004/05/cq_small_logo-310x227.jpg",

}
}
]
}
Забудьте о пустых значениях Мне просто нужна структура JSON. Пожалуйста, предложите, что не так в моем коде. Thanks
Редактировать. Мой arrayItem var_dump следующий.

Проверить '$ arrayItem [$ i] ['title']' (и все остальные элементы), это, скорее всего, сам массив. – raina77ow
Можете ли вы добавить var_dump '$ arrayItem'. Скорее всего, ваши данные отличаются от того, что вы ожидаете. –
Кажется, что $ arrayItem имеет 3 измерения вместо 2, как вы ожидаете. –
