PDO bind array to Where IN

Question

I want to bind a array of Strings to the WHERE IN part of a SQL command, which I want to run afterwards on a SQL Server. The problem is probably that I try to bind

Answer 1

Here is the snippet I use when trying to achieve an IN statement with an array.

This works dynamically, so whether you have an array of 2 or 200 it should execute as expected.

$ids = array(1,2,3);
$in  = str_repeat('?,', count($ids) - 1) . '?';
$sql = "SELECT * FROM table WHERE column IN ($in)";
$stm = $db->prepare($sql);
$stm->execute($ids);
$data = $stm->fetchAll();

Your code will look like so:

$refIdsPartial = array('54469c27c687b332339627','54469ba0dec3e703865612','54469c77945c7091266617');
$in  = str_repeat('?,', count($refIdsPartial ) - 1) . '?';
$totalCount = "SELECT referral, COUNT(username) AS cnt FROM accounts WHERE referral IN ($in) GROUP BY referral";
$ps_totalCounts = $dbh->prepare($totalCount);
$ps_totalCounts->execute();

//loop over total counts
foreach($ps_totalCounts as $row)
{
    echo "Test
";
}
