here is my custom function code

Answer 1

Let me suggest you to change this approach a bit, to make it A LOT more flexible.

• First, you definitely have to make this function accept an array with data for execute(). Otherwise there will be no sense in using prepare or PDO at all.
• Then, make your function return the statement. It will make it enormously flexible

So, change the code to this

function getdata($dbh, $sql, $params = NULL)
{
    $stmt = $dbh->prepare($sql);
    $stmt->execute($params)
    return $stmt; 
}

this way you'll be able to fetch either single record.

$row = getdata($dbh, $sql)->fetch();

or multiple rows

$row = getdata($dbh, $sql)->fetchAll();

or even run insert or update queries from which you cannot fetch at all.
