Hi all!
I have a problem in a foreach loop. Autocomplete return me the following error message:

Quote:

1st argument of foreach is recognized as *** class istance but this class is not recognized as supporting iterator interface Failed to identify type of "***" local variable

Code:

/**
* put your comment there...
*
* @param \Nextop\DataCOREBundle\Document\Flight $flights
* @return {reportFilling|\Nextop\DataCOREBundle\Document\Flight}
*/
private function fillFlights($flights){

$dmn4j = $this->doctrine_neo4j;
$dm = $this->doctrine_mongodb->getManager();
$count = 0;
$ecount = 0;
$reportFilling = Array();
foreach($flights as $flight){
/** @var $flight \Nextop\DataCOREBundle\Document\Flight */
if(!$this->ndc->flightExists($flight)){
try{
$dm->persist($flight);
$dm->flush();
$this->rf->airportFilling->ids[] = $flight->getId();//HERE
$count++;
}catch(\Exception $e){
$this->rf->airportFilling->errorsCount = ++$ecount;
}

try{
$flightN4j = new Neo4jEntity\Flight();

}catch(\Exception $e){
$this->rf->airportFilling->errorsCount = ++$ecount;
}

}
}
$this->rf->airportFilling->count = $count;
$this->dm->clear();
return $this->rf;
}
}

Any idea???
Tnx in advance

check your \Nextop\DataCOREBundle\Document\Flight class -- does it support iterator interface?

\Nextop\DataCOREBundle\Document\Flight is a single element in an array ($flights).
I don't understand..you said that $flights array must become a class and implement iterable interface?

Have a look at http://www.php.net/manual/en/class.iterator.php and it gives you an example

I think the issue is that PhpED has no way of knowing what your $flights iterates to, so cannot set $flight appropriately. Implementing the interface cures that.

If you mean that $flights is an ARRAY of Flight instances, just delare this correctly like below:

What you declared made the IDE thinking it's class, not an array, and therefore it must support iterator to be used in foreach Smile
