예제

Example #1 Committing a basic transaction

<?php
/* Begin a transaction, turning off autocommit */
$dbh->beginTransaction();

/* Insert multiple records on an all-or-nothing basis */
$sql = 'INSERT INTO fruit
    (name, colour, calories)
    VALUES (?, ?, ?)';

$sth = $dbh->prepare($sql);

foreach ($fruits as $fruit) {
    $sth->execute(array(
        $fruit->name,
        $fruit->colour,
        $fruit->calories,
    ));
}

/* Commit the changes */
$dbh->commit();

/* Database connection is now back in autocommit mode */
?>

Example #2 Committing a DDL transaction

<?php
/* Begin a transaction, turning off autocommit */
$dbh->beginTransaction();

/* Change the database schema */
$sth = $dbh->exec("DROP TABLE fruit");

/* Commit the changes */
$dbh->commit();

/* Database connection is now back in autocommit mode */
?>

Note: Not all databases will allow transactions to operate on DDL statements: some will generate errors, whereas others (including MySQL) will automatically commit the transaction after the first DDL statement has been encountered.
