PDO::commit — Commits a transaction
Commits a transaction, returning the database connection to autocommit mode until the next call to PDO::beginTransaction() starts a new transaction.
如果成功则返回 TRUE，失败则返回 FALSE。
Example #1 Commit a 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 */
?>
