Foreach PHP仅在数据库中插入最后一项

Question

i allready found some answers at other topics but not a working answer for my situation. I'm having some troubles with inserting elements of an array into my DB. (SQL Server). When using a foreach loop in PHP the loop only inserts last element of the array into db, but when i printr($arrayname) it shows the correct both elements.

Here's some of the code.

First i do a select to assign some variables: (the subquery is for removing ',' in the select)

$sql="SELECT ... FROM ...";
$query = sqlsrv_query( $conn, $sql, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));

foreach($_SESSION['cart'] as $id => $value) { 

$sql.=$id.","; 
 }         
$sql=substr($sql, 0, -1).")"; 

     if ($query){

         while($row = sqlsrv_fetch_array( $query, SQLSRV_FETCH_ASSOC) ) {

         $variable=$row['rowname'];

        }
    }

So far so good, did an echo on the $variable to test if it prints both row records, and it did.

Than i do the INSERT:

foreach($_SESSION['cart'] as $id => $value) { 

print_r($id);

$sql="INSERT INTO() ... VALUES ('$value')";
    $query= sqlsrv_query( $conn, $sql, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
}

Here's where it goes wrong, again i did a print($id) to test and see the values. It prints both values but only inserts the last element ( $variablename ) of array $id .

Please, what am i doing wrong?

Cheers.

foreach($_SESSION['cart'] as $id => $value) { 

$sql.=$id.","; 
  }         
$sql=substr($sql, 0, -1).")"; 
$query = sqlsrv_query( $conn, $sql, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));

    if ($query){

     while($row = sqlsrv_fetch_array( $query, SQLSRV_FETCH_ASSOC) ) {

     $variable=$row['rowname'];

     $sql2="INSERT INTO ()";
     $stmt= sqlsrv_query( $conn, $sql2, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
