Select problem

[carolinasolfernandez]

When I make a select query, it only returns the first row.
If I make several select (same query), it returns more rows, until I got the right result.

Example:
$test = $em->getRepository('ExampleAppBundle:App')->findAll();
echo (count($test)); //Resturns 1 row
$test = $em->getRepository('ExampleAppBundle:App')->findAll();
$test = $em->getRepository('ExampleAppBundle:App')->findAll();
$test = $em->getRepository('ExampleAppBundle:App')->findAll();
echo (count($test)); //Resturns 10 rows
