PHP prepared statements and transactions in a loop

Question

The classic transactions in a loop code:

$mysqli->query(\"START TRANSACTION\");
foreach ($pdata as $key => $value) {
    $sql    = \"INSERT INTO temp (         


        

Answer 1

Your loop can be optimized by pulling the prepare and bind_param statements out of the loop.

$value = null;
$mysqli->autocommit(FALSE);
$sql  = "INSERT INTO temp (`fund_id`) VALUES (?)";
$stmt = $mysqli->prepare($sql);
$stmt->bind_param('i', $value);
foreach ($pdata as $value) {
    $stmt->execute();
}
$mysqli->commit();

You have turned off autocommit with your autocommit(FALSE) line and therefore don't need to use the START TRANSACTION statement.
