Question

我尝试使用foreach循环更新数组中的值。然后使用更新的值打印数组。我在这里发布我当前的代码。请回复示例代码。感谢您。这是我的阵列：

[associated_branch] => Array
                (
                    [0] => Array
                        (
                            [store_id] => 0
                            [store_name] => Bazar Kolkata
                            [location] => Array
                                (
                                    [location] => Sonarpur
                                )

                            [address_line1] => J L N Road
                            [address_line2] => Kolkata
                            [city] => 4
                            [state] => 24
                        )

                    [1] => Array
                        (
                            [store_id] => 16
                            [store_name] => KC DAS
                            [location] => Array
                                (
                                    [location] => Garia Hat
                                )

                            [address_line1] => kolkata
                            [address_line2] => 
                            [city] => 4
                            [state] => 24
                        )

                )

我希望：

[associated_branch] => Array
                (
                    [0] => Array
                        (
                            [store_id] => 0
                            [store_name] => Bazar Kolkata
                            [location] => Sonarpur
                            [address_line1] => J L N Road
                            [address_line2] => Kolkata
                            [city] => 4
                            [state] => 24
                        )

                    [1] => Array
                        (
                            [store_id] => 16
                            [store_name] => KC DAS
                            [location] => Garia Hat
                            [address_line1] => kolkata
                            [address_line2] => 
                            [city] => 4
                            [state] => 24
                        )

                )

我的Sql：

$assoBrSql="SELECT store_id, store_name, location, address_line1, address_line2, city, state FROM ".DB_MY_PREFIX."my_web_stores WHERE store_id IN($row[branch_ids]) AND cur_status=1 && is_more_branch =1 AND associated_branch IS NOT NULL";
                $branches = $db->ExecuteQuery($assoBrSql);
                $row['associated_branch']=$branches;

                foreach ($row['associated_branch'] as $key => $value) {

                    $locsql="SELECT location FROM " .DB_MY_PREFIX. "my_localities WHERE location_id='".$value['location']."'";
                    $locrows=$db->ExecuteQuery($locsql);
                    $row['associated_branch'][$key]['location']=$locrows[0];

                }

如何建立这个？

Answer 1

你应该只需要改变：

$row['associated_branch'][$key]['location']=$locrows[0];

到

$row['associated_branch'][$key]['location']=$locrows[0]['location'];

您当前正在追加第二个查询的结果，该查询是一个包含单个元素“位置”的数组。

Answer 2

如果分支可以有多个位置，那么您可以更改初始查询以使用带有groupconcat的子查询来获取所有位置。像这样的东西

$assoBrSql="SELECT store_id, store_name, location, address_line1, address_line2, city, state, (SELECT GROUP_CONCAT(a.location) as locations FROM " .DB_MY_PREFIX. "my_localities a WHERE a.location_id=location) as locations FROM ".DB_MY_PREFIX."my_web_stores WHERE store_id IN($row[branch_ids]) AND cur_status=1 && is_more_branch =1 AND associated_branch IS NOT NULL";
                $branches = $db->ExecuteQuery($assoBrSql);
                $row['associated_branch']=$branches;
