PDO::commit Commits a transaction


public PDO::commit(): bool

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

Elenco dei parametri

Questa funzione non contiene parametri.

Valori restituiti

Restituisce true in caso di successo, false in caso di fallimento.


Throws a PDOException if there is no active transaction.

Nota: An exception is raised even when the PDO::ATTR_ERRMODE attribute is not PDO::ERRMODE_EXCEPTION.


Example #1 Committing a basic transaction

/* Begin a transaction, turning off autocommit */

/* 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) {

/* Commit the changes */

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

Example #2 Committing a DDL transaction

/* Begin a transaction, turning off autocommit */

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

/* Commit the changes */

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

Nota: 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.
