PDO::commit

(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)

PDO::commit Commits a transaction

Descrição

public 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.

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

Exemplos

Exemplo #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 */
?>

Exemplo #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 */
?>

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.

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