如何调整函数以实现所需的JSON结构?
请注意,现在如何将每个对象的索引设置为土地合同的ID。那不是我想要的。我想更改的另一个是,对象以称为“ landcontracts”的数组形式呈现。
function read($pdo, $Id = null) {
$params = [];
$array = [];
$sql = "SELECT lc.*,
py.AnnualPriceYear AS `Year`,
py.AnnualPriceAmount AS `Amount`
FROM LandContract AS lc
LEFT JOIN LandContractAnnualPrice AS py
ON py.LandContractId = lc.Id
";
if ($Id) {
$sql .= 'WHERE lc.Id = ?';
$params[] = $Id;
}
$stmt = $pdo->prepare($sql);
$stmt->execute($params);
while ($row = $stmt->fetch()) {
// Fields we want to extract from the select statement into the array
$select_fields = ['Id', 'Name', 'LocationId', 'Link', 'Notes', 'LandOwnerId',
'StartDate', 'EndDate', 'IsTerminated', 'PaymentInterval',
'PriceType', 'FixedAnnualPrice '];
if (!isset($array[$row['Id']])) {
// initialize the subarray if it has not been set already
$array[$row['Id']] = array_intersect_key($row, array_flip($select_fields));
if ($row['Year'] != null) {
$array[$row['Id']]['AnnualPrices'] = [];
} else {
$array[$row['Id']]['AnnualPrice'] = $row['FixedAnnualPrice'];
}
}
if ($row['Year'] != null) {
$array[$row['Id']]['AnnualPrices'][] = ['Year' => $row['Year'], 'Amount' => $row['Amount']];
}
}
if (empty($array)) {
echo "No results";
exit;
}
echo json_encode($array, JSON_UNESCAPED_UNICODE);
$stmt = null;
}

您可以使用正确的键将结果数组包装在另一个关联数组中,然后使用原始数组的config.json
来重置键。
例如:
array_values
