PDO::commit — Commits a transaction

### Opis

bool PDO::commit ( void )

Commits a transaction, returning the database connection to autocommit mode until the next call to PDO::beginTransaction() starts a new transaction.

### Zwracane wartości

Zwraca `TRUE` w przypadku powodzenia, `FALSE` w przypadku błędu.

### Przykłady

Przykład #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 */
?>`

Przykład #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 */
?>`

> Informacja: 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.
