Foreach need help?

$userIdList is an array that contains users ids!

I can’t make this foreach to loop though all of them! It only gets the first id?

foreach ($userIdList as $userId)        
{
$questions = BOL_UserService::getInstance()->getUserViewQuestions($userId);

if ( !empty($questions['data'][$userId]) )
        {
            $data = array();
            $test= array();
            foreach ( $questions['data'][$userId] as $key => $value )
            {
                if ( is_array($value) )
                {
                    $questions['data'][$userId][$key] = implode(', ', $value);
                    $test[] = $questions['data'];
                }
            }
        }
}
print_r($test);

This seem to work but it duplicates all the results!

$test= array();            
foreach ($userIdList as $userId)        
{
$questions = BOL_UserService::getInstance()->getUserViewQuestions($userId);

if ( !empty($questions['data'][$userId]) )
        {
            $data = array();

            foreach ( $questions['data'][$userId] as $key => $value )
            {
                if ( is_array($value) )
                {
                    $questions['data'][$userId][$key] = implode(', ', $value);
                    $test[] = $questions['data'];
                }
            }
        }
}
print_r($test);

Hard to comment without seeing what comes back in $questions.

Should the assignment to $test only occur if $value is an array, or should that line happen regardless, and the implode() only happen in that case?
