想要将具有唯一值的多维数组值插入 php 数据库

Question

I have one multidimensional-array and i want to insert into my database, there is one issue if one entry in my database and same entry is on my multidimensional-array that value should not insert again in my database.

$activity[] = array('user_id'=> $_SESSION['user_id'], 'choosen_date' => $ch_date, 'distance' => $distance, 'pace' => $pace );

Array
(
    [0] => Array
        (
            [user_id] => 1200
            [choosen_date] => 2018-12-11
            [distance] => 1.72
            [pace] => 12.4812
        )
[1] => Array
    (
        [user_id] => 1200
        [choosen_date] => 2018-12-09
        [distance] => 3.17
        [pace] => 3.8736
    )

[2] => Array
    (
        [user_id] => 1200
        [choosen_date] => 2018-11-14
        [distance] => 2.26
        [pace] => 6.3504
    )

[3] => Array
    (
        [user_id] => 1200
        [choosen_date] => 2018-11-07
        [distance] => 0.53
        [pace] => 3.6576
    )

)

And following is my database entry

----------------------------------------------------
| S.No | user Id | choose date | distance |  Pace  |
----------------------------------------------------
|  1   |  1200   | 2018-12-09  |   3.17   | 3.8736 |
----------------------------------------------------
|  2   |  1200   | 2018-12-11  |   2.17   |  5.67  |
----------------------------------------------------

so here, in database S.no 1 and array index 1 both are the same entry so I want to insert rest value into my database. So how can I insert?

Answer 1

I am assuming that you are using MySQL database, you can use INSERT IGNORE INTO

or INSERT ON DUPLICATE KEY UPDATE

Answer 2

If you want to do it through PHP then you can try this.

$i=0;
foreach($activity as $key=>$val)
{
  $sn_check=mysqli_query($con,"SELECT id FROM table WHERE S.No='$i'");
  if(mysqli_num_rows($sn_check)==0)
  {
     $user_id=$val[$i]['user_id']; //all other values can be catch like this.
     $query_insert=mysqli_query($con,"INSERT QUERY");
  }
$i++;
}
