transaction()
transaction(\RedBeanPHP\Adapter $adapter, callable $callback) : mixed
Wraps a transaction around a closure or string callback.
If an Exception is thrown inside, the operation is automatically rolled back. If no Exception happens, it commits automatically. It also supports (simulated) nested transactions (that is useful when you have many methods that needs transactions but are unaware of each other).
Example:
$from = 1;
$to = 2;
$amount = 300;
R::transaction(function() use($from, $to, $amount) { $accountFrom = R::load('account', $from); $accountTo = R::load('account', $to); $accountFrom->money -= $amount; $accountTo->money += $amount; R::store($accountFrom); R::store($accountTo); });
Parameters
| \RedBeanPHP\Adapter | $adapter | Database Adapter providing transaction mechanisms. |
| callable | $callback | Closure (or other callable) with the transaction logic |
