Quick Start

Creating Questions

use Tourze\QuestionBankBundle\DTO\QuestionDTO;
use Tourze\QuestionBankBundle\DTO\OptionDTO;
use Tourze\QuestionBankBundle\Enum\QuestionType;
use Tourze\QuestionBankBundle\Service\QuestionServiceInterface;

// Create question
$questionDTO = new QuestionDTO();
$questionDTO->title = 'Which of the following is a PHP superglobal variable?';
$questionDTO->content = 'Please select the correct answer';
$questionDTO->type = QuestionType::SINGLE_CHOICE;
$questionDTO->difficulty = 2;
$questionDTO->score = 10.0;

// Add options
$questionDTO->options = [
    OptionDTO::create('$_GET', true),
    OptionDTO::create('$get', false),
    OptionDTO::create('$GET', false),
    OptionDTO::create('$_get', false),
];

// Save question
$question = $questionService->createQuestion($questionDTO);

Searching Questions

use Tourze\QuestionBankBundle\DTO\SearchCriteria;
use Tourze\QuestionBankBundle\Enum\QuestionType;

$criteria = new SearchCriteria();
$criteria->setKeyword('PHP')
    ->setTypes([QuestionType::SINGLE_CHOICE])
    ->setMinDifficulty(1)
    ->setMaxDifficulty(3)
    ->setLimit(20);

$result = $questionService->searchQuestions($criteria);

Category Management

use Tourze\QuestionBankBundle\DTO\CategoryDTO;
use Tourze\QuestionBankBundle\Service\CategoryServiceInterface;

// Create category
$categoryDTO = CategoryDTO::create('Programming Languages', 'programming');
$category = $categoryService->createCategory($categoryDTO);

// Create subcategory
$phpDTO = CategoryDTO::create('PHP', 'php');
$phpDTO->parentId = $category->getId()->toString();
$php = $categoryService->createCategory($phpDTO);

Core Concepts

Question Types

Single Choice (SINGLE_CHOICE) - Only one correct answer
Multiple Choice (MULTIPLE_CHOICE) - Can have multiple correct answers
True/False (TRUE_FALSE) - Only true/false options
Fill in the Blank (FILL_IN_THE_BLANK) - Requires text input
Short Answer (SHORT_ANSWER) - Open-ended response

Question Status

Draft (DRAFT) - Question is being edited
Published (PUBLISHED) - Question is ready for use
Archived (ARCHIVED) - Question is disabled

Difficulty Levels

Question difficulty ranges from 1-5:

Level 1: Very Easy
Level 2: Easy
Level 3: Medium
Level 4: Hard
Level 5: Very Hard

Entity Structure

Question

id: Unique identifier
title: Question title
content: Question content
type: Question type
difficulty: Difficulty level
score: Default score
explanation: Answer explanation
status: Publication status

Option

id: Unique identifier
content: Option content
isCorrect: Whether it's a correct answer
sortOrder: Sort order

Advanced Usage

Batch Operations and Transaction Management

// Batch question import example
class QuestionBatchImporter
{
    public function importQuestions(array $questionsData): ImportResult
    {
        $result = new ImportResult();
        
        $this->entityManager->beginTransaction();
        try {
            foreach ($questionsData as $data) {
                $dto = $this->buildQuestionDTO($data);
                $question = $this->questionService->createQuestion($dto);
                $result->addSuccess($question);
            }
            
            $this->entityManager->commit();
        } catch (\Exception $e) {
            $this->entityManager->rollback();
            $result->addError('Batch import failed', $e->getMessage());
        }
        
        return $result;
    }
}

Custom Search Engine

// Elasticsearch integration
class ElasticsearchQuestionSearcher
{
    public function search(SearchCriteria $criteria): PaginatedResult
    {
        $query = [
            'bool' => [
                'must' => []
            ]
        ];
        
        // Add keyword search
        if ($criteria->getKeyword()) {
            $query['bool']['must'][] = [
                'multi_match' => [
                    'query' => $criteria->getKeyword(),
                    'fields' => ['title^2', 'content']
                ]
            ];
        }
        
        // Add category filter
        if ($criteria->getCategoryIds()) {
            $query['bool']['filter'][] = [
                'terms' => ['category_ids' => $criteria->getCategoryIds()]
            ];
        }
        
        return $this->executeSearch($query, $criteria);
    }
}

Best Practices

Use DTOs for data transfer - Avoid direct entity manipulation
Operate through service interfaces - For better testing and extensibility
Use caching wisely - Category trees and popular tags are good candidates
Use transactions for batch operations - Ensure data consistency
Listen to events for extensions - Instead of modifying core code

Testing

# Run all tests

FAQ

Q: How to implement random question selection?

A: Use the QuestionRepository's findRandom method:

$randomQuestions = $questionRepository->findRandom(
    limit: 10,
    criteria: $searchCriteria
);

Q: How to implement question versioning?

A: Listen to question update events:

class QuestionVersionListener
{
    public function onQuestionUpdated(QuestionUpdatedEvent $event): void
    {
        $question = $event->getQuestion();
        // Save historical version
        $this->versionService->createSnapshot($question);
    }
}
