$con = Propel::getConnection();
$stmt = $con->prepareStatement('SELECT foo, bar FROM baz WHERE name=? AND active=?');
$stmt->setString(1, 'MyName');
$stmt->setString(2, '1');
$rs = $stmt->executeQuery(ResultSet::FETCHMODE_NUM);

Ou encore plus con :

Propel::getConnection()->executeUpdate('SET FOREIGN_KEY_CHECKS=0');

Merci Thibs ;)

$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) 
{
  $value = $value * 2;
}
print_r($arr); // $arr vaut maintenant array (2, 4, 6, 8)

sfLoader::loadHelpers(array('First', 'Second'));

Simple !

Au choix :

$ pstree

ou :

$ ps afx

Sur l'ancienne machine :

$ svnadmin dump /var/lib/subversion/myproject > ~/myproject.svndump
$ scp ~/myproject.svndump new-server:

Sur la nouvelle machine :

$ svnadmin create /var/lib/subversion/myproject
$ svnadmin load /var/lib/subversion/myproject < ~/myproject.svndump
