i wonder if there is a way to search for a document field looking like :
JavaScript
x
/**
* @var array
*
* @ORMColumn(name="tags", type="array", nullable=true)
*/
private $tags;
which in database looks like php array interpretation :
JavaScript
a:3:{i:0;s:6:"tagOne";i:1;s:6:"tagTwo";i:2;s:8:"tagThree";}
now i try to search the entity by a tag tryed
JavaScript
public function findByTag($tag) {
$qb = $this->em->createQueryBuilder();
$qb->select('u')
->from("myBundle:Entity", 'u')
->where('u.tags LIKE :tag')
->setParameter('tag', $tag );
$result=$qb->getQuery()->getResult();
return $result;
}
which always returns array[0]
just dont get it
i am able to change the way how they are saved for any help, thanks in advance

Answer
You need to define a literal
tag for %
before and/or after the value you want to search; in this case you won’t even need to have single quotation before and after your phrase:
JavaScript
$qb = $this->em->createQueryBuilder();
$qb->select('u')
->from("myBundle:Entity", 'u')
->where($qb->expr()->like('u.tags', $qb->expr()->literal("%$tag%")))
$result=$qb->getQuery()->getResult();
return $result;
You can follow a list of all Doctrine expr class
