Not sure if this is possible but im trying to run array_unique over a collection of items i have, to remove duplicates. Although i cannot get it working.
my controller logic:
// init models
$jobs = Job::search();
$countries = $jobs->get()->map(function( $job ) {
return $job->country;
});
$countries = array_unique( $countries->toArray() );
although this gets a "Array to string conversion" error
