PDO::commit Commits a transaction


public PDO::commit ( void ) : bool

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

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului.


Throws a PDOException if there is no active transaction.

Notă: O excepție este emisă chiar atunci când atributul PDO::ATTR_ERRMODE nu are valoarea 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 */

Notă: 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.

Keep in mind this bug: https://bugs.php.net/bug.php?id=66528

you could not rely on commit() return value while using MySql

Note that this will raise the PDOException on error EVEN if the error handling of PDO is set to PDO::ERRMODE_WARNING.
