插入多維數組到MySQL表的key和值

Question

我有一個數組，看起來像這樣

Array 
(
    [0] => Array 
     (
      [post_id] => 5410 
      [Issue] => 201 
      [volume] => 2 
      [pages] => 105-9 
      [authors] => Onger, M., Jaluth, K. 
      [publication_date] => 17 January 2016 
      [journals] => Nature Medicine 
      [link_to_pubmed] => http://www.ncbi.nlm.nih.gov/pubmed/1 
     ) 
    [1] => Array 
     (
      [post_id] => 5411 
      [Issue] => 301 
      [volume] => 7 
      [pages] => 32-9 
      [authors] => Onger, M., Jaluth, K. 
      [publication_date] => March 30 
      [journals] => Lancet 
      [link_to_pubmed] => http://www.ncbi.nlm.nih.gov/pubmed/2 
     ) 
     ) 

我已經開裂我的頭整天試圖找出如何我可以同時插入鍵和值得到的東西看起來像這樣

+---------+---------+-------------------+-----------------------+ 
| meta_id | post_id | meta_key   | meta_value   | 
+---------+---------+-------------------+-----------------------+ 
| 190143 | 5410 |Issue    | 201     | 
| 190141 | 5410 |volume    | 2      | 
| 190140 | 5410 |pages    | 105-109    | 
| 190139 | 5410 |authors   | Onger, M., Jaluth, K. | 
| 190144 | 5410 |publication_date | 17 January 2016  | 
| 190136 | 5410 |journals   | Nature Medicine  | 
| 190135 | 5410 |link_to_pubmed  |      | 
|   |   |     |      | 
+---------+---------+-------------------+-----------------------+

我如何獲得關鍵和值？

Answer 1

如果meta_id是一個自動增量字段，然後

foreach($publications as $publication) { 
    // Get post_id and remive it from array 
    $post_id = $publication['post_id']; 
    unset($publication['post_id']); 
    foreach ($publication as $key => $metadata) { 
     // Below a query. I only print it, you need to execute it 
     echo $query = 'insert into table (post_id, meta_key, meta_value) 
         values ($post_id, "' . $key . '", "' . $metadata . '")'; 
     } 
} 

Answer 2

你不能用1個查詢來完成。 你必須運行數組的循環，並在每一行運行INSERT mysql。
