From the start Doctrine has been designed to work with multiple connections. Unless separately specified Doctrine always uses the current connection
|
|
for executing the queries. The following example uses openConnection() second argument as an optional
|
|
connection alias.
|
|
<br \><br \>
|
|
<?php
|
|
renderCode("<?php
|
|
// Doctrine_Manager controls all the connections
|
|
|
|
\$manager = Doctrine_Manager::getInstance();
|
|
|
|
// open first connection
|
|
|
|
\$conn = \$manager->openConnection(new PDO('dsn','username','password'), 'connection 1');
|
|
?>
|
|
");
|
|
?>
|
|
<br \><br \>
|
|
For convenience Doctrine_Manager provides static method connection() which opens new connection when arguments are given to it and returns the current
|
|
connection when no arguments have been speficied.
|
|
<br \><br \>
|
|
<?php
|
|
renderCode("<?php
|
|
// open first connection
|
|
|
|
\$conn = Doctrine_Manager::connection(new PDO('dsn','username','password'), 'connection 1');
|
|
|
|
\$conn2 = Doctrine_Manager::connection();
|
|
|
|
// \$conn2 == \$conn
|
|
?>
|
|
");
|
|
?>
|
|
|
|
|
|
<br \><br \>
|
|
The current connection is the lastly opened connection.
|
|
<br \><br \>
|
|
<?php
|
|
renderCode("<?php
|
|
// open second connection
|
|
|
|
\$conn2 = \$manager->openConnection(new PDO('dsn2','username2','password2'), 'connection 2');
|
|
|
|
\$manager->getCurrentConnection(); // \$conn2
|
|
?>");
|
|
?>
|
|
<br \><br \>
|
|
You can change the current connection by calling setCurrentConnection().
|
|
<br \><br \>
|
|
<?php
|
|
renderCode("<?php
|
|
\$manager->setCurrentConnection('connection 1');
|
|
|
|
\$manager->getCurrentConnection(); // \$conn
|
|
?>
|
|
");
|
|
?>
|
|
<br \><br \>
|
|
You can iterate over the opened connection by simple passing the manager object to foreach clause. This is possible since Doctrine_Manager implements
|
|
special IteratorAggregate interface.
|
|

|
|
<?php
|
|
renderCode("<?php
|
|
// iterating through connections
|
|
|
|
foreach(\$manager as \$conn) {
|
|
|
|
}
|
|
?>");
|
|
?>
