如何在php中为数组添加值

Question

我有一个示例代码：

$size_arr = array(35, 36, 37, 38, 39)

这是phpmyadmin

$result = array();
$data = array(); // query get from table
foreach ($data as $row) {
  $result [$row->product_id][] = array($row->color => array($row->size));
}
var_dump($result);

如何为结果数组添加更多的值大小

array(
   [1] => array(
      'Black' => array(35 => 0, 36 => 40, 37 => 5, 38 => 0, 39 => 20), 
      'White' => array(35 => 0, 36 => 8, 37 => 12, 38 => 20, 39 => 0)
   )
)

非常简单地将颜色和行大小添加为子数组键

$result = array();
$data = array(); // query get from table
foreach ($data as $row) {
    $result [$row->product_id][$row->color][$row->size] = $row->quantity;
}
var_dump($result);
