Symfony2 repository query not working - symfony

Question

I am developing an application using Symfony2 and DQL for building some queries in the repositories. I have the next code in the controller:
$emGalPak = $this->getDoctrine()->getEntityManager();
$OsatugabeKop = $emGalPak->getRepository('AnotatzaileaAnotatzaileaBundle:GalderaPaketea')
->getOsatugabeKop();
and this is the query I built in the repository corresponding to the entity mentioned above:
<?php
namespace Anotatzailea\AnotatzaileaBundle\Repository;
use Doctrine\ORM\EntityRepository;
/**
* GalderaPaketeaRepository
*
* This class was generated by the Doctrine ORM. Add your own custom
* repository methods below.
*/
class GalderaPaketeaRepository extends EntityRepository
{
public function getOsatugabeKop()
{
$qb = $this->createQueryBuilder('c')
->select('c')
->where('c.Osatua = 0')
$Emaitza = $qb->getQuery()->getResult();
return sizeof($Emaitza);
}
}
When running the code it shows the next error:
Parse error: syntax error, unexpected T_VARIABLE in /var/www/Symfony/src/Anotatzailea/AnotatzaileaBundle/Repository/GalderaPaketeaRepository.php on line 20
Any idea on how I can solve this error?

Answer 1

This has nothing to do with your query not working.
When you see a "Parse error" that means your PHP code itself is improperly formatted and the PHP engine cannot even parse it, let alone run it.
In this particular case, you're missing a semicolon at the end of your expression creating the query builder.
public function getOsatugabeKop()
{
$qb = $this->createQueryBuilder('c')
->select('c')
->where('c.Osatua = 0'); // <--- right there
$Emaitza = $qb->getQuery()->getResult();
return sizeof($Emaitza);
}
When you get the unexpected T_VARIABLE error that's almost always because you omitted a semicolon and the parser encountered a variable before it thought it should. It's easier to see the mistake if you take out the whitespace.
// Bad Code, two lines
$now = time()
$one = 1;
// Bad Code, one line
$now = time()$one = 1;
// ----------^ Pretty obvious now that a semicolon is missing
// And that a variable was encountered unexpectedly
Cheers

Answer 2

Semicolon missing after where line.
