当我使用find（'all'）使用我的cakephp查询从数据库中获取数据时，它返回一个数组。好的，然后结果数组不舒服，我喜欢在页面上显示这些数据。意味着它生成多行。我在谷歌上查了但没有找到回复。
注意：数组过滤器应该符合Array ['DispensaryInventory'] ['product_id']
我的数组是：

更新：
我试过了。
foreach($dispensary_inventory_data as $k1=>$a1){
foreach($dispensary_inventory_data as $k2=>$a2){
if($k1 < $k2 && $a1["DispensaryInventory"]["product_id"] == $a2["DispensaryInventory"]["product_id"]){
$dispensary_inventory_data[$k1]["ProductOption"][] = $a2["ProductOption"];
$dispensary_inventory_data[$k1]["Product"][] = $a2["Product"];
if(isset($dispensary_inventory_data[$k1]["Product"]["id"])){
$dispensary_inventory_data[$k1]["Product"][] = array(
"id"=>$dispensary_inventory_data[$k1]["Product"]["id"],
"name"=>$dispensary_inventory_data[$k1]["Product"]["name"],
"quantity"=>$dispensary_inventory_data[$k1]["Product"]["quantity"]
);
$dispensary_inventory_data[$k1]["ProductOption"][] = array(
"id"=>$dispensary_inventory_data[$k1]["ProductOption"]["id"],
"value"=>$dispensary_inventory_data[$k1]["ProductOption"]["value"],
"unit"=>$dispensary_inventory_data[$k1]["ProductOption"]["unit"]
);
unset($dispensary_inventory_data[$k1]["Product"]["id"]);
unset($dispensary_inventory_data[$k1]["Product"]["name"]);

答案 0 :(得分：1)
您可以使用php array_column函数并将数组重新组织为具有所需结构和最小工作量的新数组：
$result = array();
$result['DispensaryInventory'] = array_column($data, 'DispensaryInventory');
$result['ProductOption'] = array_column($data, 'ProductOption');
$result['Product'] = array_column($data, 'Product');

更新
使用此功能将数组转换为您需要的格式：
function my_format($data)
{
$data2 = array();
foreach($data as $val)
{
$keys = array_keys($val);
// you can also use $val['DispensaryInventory']['product_id'] here,
// but i take it these refer to the same thing
$product_id = $val['Product']['id'];
if (!isset($data2[$product_id])) $data2[$product_id] = array();
foreach($keys as $key)
{
if ( 'Product' === $key ) $data2[$product_id][$key] = $val[$key];
elseif ( !isset($data2[$product_id][$key]) ) $data2[$product_id][$key] = array($val[$key]);
else $data2[$product_id][$key][] = $val[$key];
}
}
return array_values($data2); // you can also return the $data2 here
}
像这样使用：
$new_data = my_format($data);
（预期）输出（未测试）
