PDO::commit

(PHP 5 >= 5.1.0, PHP 7, PHP 8, PECL pdo >= 0.1.0)

PDO::commit — Commits a transaction

Description

publicPDO::commit(): bool

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

Parameters

This function has no parameters.

Return Values

Returns true on success or false on failure.

Errors/Exceptions

Throws a PDOException if there is no active transaction.

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

Examples

Example #1 Committing a basic transaction

<?php

$dbh->beginTransaction();


$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,
 ));
}


$dbh->commit();


?>

Example #2 Committing a DDL transaction

<?php

$dbh->beginTransaction();


$sth = $dbh->exec("DROP TABLE fruit");


$dbh->commit();


?>

Note: 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.
