Oracle procedure does't executes calling from PHP - php

Question

I'm facing with problem executing Oracle Procedure from PhP. Actually, I am using Doctrine to execute it.
What is interesting is the fact of any other Queries can be executed/fetched, but procedures.
Below, you can find the codes I managed to use, this Select works wonderfully:
$connection = $this->getApplication()->getDataSourceManager()->getEntityConnection();
$stmt = $connection->prepare("SELECT SYSDATE FROM DUAL"); //or any other select works nice
$stmt->execute();
However, any procedure wont work, this is one of them:
$connection = $this->getApplication()->getDataSourceManager()->getEntityConnection();
$stmt = $connection->prepare("call prc_nutr_values('$cdfil', '$cdserice', '001', '0000000036', 'S', '$selectdt', '$selectdt')");
$stmt->execute();
The procedure above, doesn't surge any changes in DB. It doesn't his procedure

Answer 1

Error found!
The main problem was that PhP doesn't throw any error (I don't know why. However, I made the transaction in a different way, creating a clean new connection and it threw the error, as following:
$entitiesPath = realpath(__DIR__."/../src/");
$isDevMode = true;
$entity_metadata_config = \Doctrine\ORM\Tools\Setup::createAnnotationMetadataConfiguration(array($entitiesPath), $isDevMode);
$connection_params = array(
'driver' => 'oci8',
'user' => 'user',
'password' => 'pwd',
'host' => 'IP',
'port' => 'port',
'dbname' => 'ORCL',
);
$entity_manager = \Doctrine\ORM\EntityManager::create($connection_params, $entity_metadata_config);
$conn=$entity_manager->getConnection();
$sql ="CALL FUNCTION_NAME('$param1', '$param2', '$param3', '$param4', '$param5', $param6, $param7)";
$outputMeta = $conn->exec($sql);
Connecting through this way, I could receive the error detailed:
it was $param6 and $param7 (non-formatted dates)
to solve this...
I just replace $param6 and $param7 with TO_DATE('$param6', 'DATE-FORMAT') and TO_DATE('$param7', 'DATE-FORMAT')
where 'DATE-FORMAT' is the used date format ('MM/DD/YYYY', or other used date formats)
