Question

我有这个数组：

Array 
(
    [key] => 123456
    [siteNumber] => 123456
    [useBalanceOnly] => 80
    [coupon] => free50
    [deliveryAddress.countryId] => IN
    [deliveryAddress.state] => GUJ
    [deliveryAddress.city] => Ahmedabad
    [deliveryAddress.company] => abc
    [deliveryAddress.address] => abc
    [deliveryAddress.address2] => abc
    [deliveryAddress.postcode] => 123
    [deliveryAddress.receiver] => 1
    [deliveryAddress.telephone] => 123456789
    [deliveryAddress.shippingWayId] => 2
    [0] => Array
    (
        [0] => Array
        (
            [items.1.itemNo] => 51
            [items.1.qty] => 8
        )

        [1] => Array
        (
            [items.2.itemNo] => 52
            [items.2.qty] => 2
        )
    )
)

我想把它变成这样：

Array
(
    [key] => 123456
    [siteNumber] => 123456
    [useBalanceOnly] => 80
    [coupon] => free50
    [deliveryAddress.countryId] => IN
    [deliveryAddress.state] => GUJ
    [deliveryAddress.city] => Ahmedabad
    [deliveryAddress.company] => abc
    [deliveryAddress.address] => abc
    [deliveryAddress.address2] => abc
    [deliveryAddress.postcode] => 123
    [deliveryAddress.receiver] => 1
    [deliveryAddress.telephone] => 123456789
    [deliveryAddress.shippingWayId] => 2
    [items.1.itemNo] => 51
    [items.1.qty] => 8
    [items.2.itemNo] => 52
    [items.2.qty] => 2
)

这是我到目前为止的代码：

$p = $db->query("select * from table");
$no = 0;
while($row = $p->fetch_array()){
    $no = $no +1;
    $user_result[] = array(
        "items.".$no.".itemNo" => $row['itemno'],
        "items.".$no.".qty" => $row['itemqty']
    );
}

$parameters = array(
    'key' => 123456,
    'siteNumber' => '123456',
    'useBalanceOnly' => '80',
    'coupon' => 'free50',
    'deliveryAddress.countryId' => 'IN',
    'deliveryAddress.state' => 'GUJ',
    'deliveryAddress.city' => 'Ahmedabad',
    'deliveryAddress.company' =>'abc',
    'deliveryAddress.address' => 'abc',
    'deliveryAddress.address2' => 'abc',
    'deliveryAddress.postcode' => '123',
    'deliveryAddress.receiver' => '1',
    'deliveryAddress.telephone' => '123456789',
    'deliveryAddress.shippingWayId' => '2',
    $user_result
);

print_r($parameters);

使用array_merge()，它将结果合并到数组中。（或直接使用array operators）。您还希望以不同的方式设置$user_result的格式，以使其形成一个数组，而不是子数组：

$p = $db->query("select * from table");
$no = 0;
$user_result = array();
while($row = $p->fetch_array()){
    $no = $no +1;
    $user_result["items.".$no.".itemNo"] = $row['itemno'];
    $user_result["items.".$no.".qty"] = $row['itemqty'];
}
$parameters = array(
    'key'       => 123456,
    'siteNumber' => '123456',
    'useBalanceOnly'    => '80',
    'coupon'      => 'free50',
    'deliveryAddress.countryId' => 'IN',
    'deliveryAddress.state' => 'GUJ',
    'deliveryAddress.city' => 'Ahmedabad',
    'deliveryAddress.company' =>'abc',
    'deliveryAddress.address' => 'abc',
    'deliveryAddress.address2' => 'abc',
    'deliveryAddress.postcode' => '123',
    'deliveryAddress.receiver' => '1',
    'deliveryAddress.telephone' => '123456789',
    'deliveryAddress.shippingWayId' => '2',
) + $user_result;

就我个人而言，我只是将其堆叠到参数数组的末尾，而不是完全形成2个数组：

$parameters = [
    'key'                           => 123456,
    'siteNumber'                    => '123456',
    'useBalanceOnly'                => '80',
    'coupon'                        => 'free50',
    'deliveryAddress.countryId'     => 'IN',
    'deliveryAddress.state'         => 'GUJ',
    'deliveryAddress.city'          => 'Ahmedabad',
    'deliveryAddress.company'       => 'abc',
    'deliveryAddress.address'       => 'abc',
    'deliveryAddress.address2'      => 'abc',
    'deliveryAddress.postcode'      => '123',
    'deliveryAddress.receiver'      => '1',
    'deliveryAddress.telephone'     => '123456789',
    'deliveryAddress.shippingWayId' => '2',
];

$p = $db->query("select * from table");
$no = 0;
while($row = $p->fetch_array()){
    $no++; // Or $no += 1; Or $no = $no + 1;
    $parameters["items.{$no}.itemNo"] = $row['itemno'];
    $parameters["items.{$no}.qty"]    = $row['itemqty'];
}

Answer 2

实际上，您将$ user_result数组作为大数组中的一项进行制作。您需要将它们合并。

您是否尝试过数组合并？

array_merge($parameters,$user_result);

Answer 3

如果您希望最终结果是平面（一维）数组，请在获取结果之前定义$parameters数组，而不是将结果添加到单独的数组并将该数组附加到$parameters，只需将新数据添加到$parmameters：

$parameters = array(
        'key'       => 123456,
        // rest of $parameters array
        'deliveryAddress.shippingWayId' => '2',
        );
$no = 0;
while($row = $p->fetch_array()){
    $no = $no +1;
    //do not add new array to the $user_data, simply create new keys
    $parameters ["items.{$no}.itemNo"] = $row['itemno'];
    $parameters ["items.{$no}.qty"] = $row['itemqty'];

}

或者，您可以构建另一个数组，例如$user_data，但避免使其成为多维数组（即，不要为每行向$user_data添加新数组，因为无论如何您都在创建唯一索引）然后使用array_merge或+运算符将它们合并。

但是，如果您确实需要$user_data作为多维数组（例如，现在在代码中的方式，例如，如果该数组的唯一用途不附加到$parameters并且您将按原样使用它）可以尝试flatten it，然后将其与$parameters合并。

if you want itemno and itemqtty in aequence try this one:

$parameters = array(
    'key' => 123456,
    'siteNumber' => '123456',
    'useBalanceOnly' => '80',
    'coupon' => 'free50',
    'deliveryAddress.countryId' => 'IN',
    'deliveryAddress.state' => 'GUJ',
    'deliveryAddress.city' => 'Ahmedabad',
    'deliveryAddress.company' =>'abc',
    'deliveryAddress.address' => 'abc',
    'deliveryAddress.address2' => 'abc',
    'deliveryAddress.postcode' => '123',
    'deliveryAddress.receiver' => '1',
    'deliveryAddress.telephone' => '123456789',
    'deliveryAddress.shippingWayId' => '2',
);


$p = $db->query("select * from table");    
$no=0;
while($row = $p->fetch_array())
{
    $no++; 
    $parameters["items.{$no}.itemNo"] => $row['itemno'],       
}

$no1 = 0;
while($row1 = $p->fetch_array())
{
    $no1++;
    $parameters["items.{$no1}.itemNo"] => $row1['itemqty']
}
print_r($parameters);
