我有一個 foreach 但它只回傳最后一個值而不是所有值，有什么問題？
我的陣列
array:1 [▼
"ciudad" => array:15 [▼
0 => "Piura"
1 => "10"
2 => "0"
3 => "Lima"
4 => "20"
5 => "0"
6 => "Pisco"
7 => "30"
8 => "0"
9 => "Arequipa"
10 => "40"
11 => "0"
12 => "Loreto"
13 => "50"
14 => "0"
]
]
我的代碼：
public function updateciudadpreciosdelivery(Request $request)
{
$data = $request->except(['_token', 'restaurant_id']);
$i = 0;
$result = [];
foreach ($data as $day => $times) {
$day_result = [];
foreach ($times as $key => $time) {
if ($key % 3 == 0) {
$day_result["open"] = $time;
}
elseif ($key % 2 == 0) {
$day_result["cod"] = $time;
}
else {
$day_result["close"] = $time;
}
}
$result[$day][] = $day_result;
}
// Fetches The Restaurant
$restaurant = Restaurant::where('id', $request->restaurant_id)->first();
// Enters The Data
if (empty($result)) {
$restaurant->deliveryciudadprecios = null;
}
else {
$restaurant->deliveryciudadprecios = json_encode($result);
}
$restaurant->delivery_charge_type = 'XCIUDAD';
// Saves the Data to Database
$restaurant->save();
return redirect()->back()->with(['success' => 'Las ciudades se guardaron correctamente']);
}
目前它只回傳最后一個值
"{"ciudad":[{"open":"Loreto","close":"50","cod":"0"}]}"
我需要您回傳以下內容（示例）
{"ciudad":[{"open" :"Piura","close" :"10","cod" :"0"},{"open" :"Lima","close" :"20","cod" :"0"},{"open" :"Pisco","close" :"30","cod" :"0"},{"open" :"Arequipa","close" :"40","cod" :"0"},{"open" :"Loreto","close" :"50","cod" :"0"}]}
如果不清楚，我會嘗試改進它
uj5u.com熱心網友回復：
如果我們認為您的資料不會改變，并且您有 3 個條目要獲取，您可以使用array_chunk：
$result = [];
foreach ($data as $day => $times) {
$timesChunked = array_chunk($times, 3);
foreach ($timesChunked as $time) {
$result[$day] []= [
'open' => $time[0],
'close' => $time[1],
'code' => $time[2],
];
}
}
但是您的問題是合乎邏輯的，您不會更改回圈中的鍵，當然您的陣列將只有最后一個元素。重新閱讀您的代碼，并嘗試了解原因。
