Detailed explanation of query examples of Symfony2 based on input time
Generally: when the front-end inputs a time, we usually modify the time into a timestamp firststrtotime - Parse the date and time description of any English text into a Unix timestamp. This article mainly introduces it to you. Symfony2's method of querying the input time, combined with examples, analyzes the related operating techniques of Symfony2 for converting and querying the input time of mysql and MongoDB. Friends who need it can refer to it. I hope it can help everyone.
For example:
$startTimestamp = strtotime($startDate); $endTimestamp = strtotime($endDate);
Then: If it is just time, in order to prevent the time passed by others from being false, you need to modify the time into the form of Y-m-d
$start = date('Y-m-d 00:00:00', $startTimestamp); $end = date('Y-m-d 23:59:59', $endTimestamp);
1. Use in MySQL
if(empty($startDate)) { throw new \Exception('起始时间不为空', BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } if (empty($endDate)) { $endDate = $startDate; } $startTimestamp = strtotime($startDate); $endTimestamp = strtotime($endDate); if ($startTimestamp > $endTimestamp) { throw new \Exception('时间参数错误', BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } if ($status == InventoryOrder::STATUS_SUBMITTED) { $index = 'i.submitTime'; } else if ($status == InventoryOrder::STATUS_UNSUBMITTED) { $index = 'i.createTime'; } else if (empty($status)) { $index = 'i.createTime'; } else { throw new \Exception('时间格式不正确', BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } $sql = 'SELECT i FROM AppBundle:InventoryOrder i WHERE '; $sql .= $index; $sql .= ' BETWEEN :startDate AND :endDate '; $start = date('Y-m-d 00:00:00', $startTimestamp); $end = date('Y-m-d 23:59:59', $endTimestamp); $params['endDate'] = $end; $params['startDate'] = $start; if (!empty($status)) { $sql .= ' AND i.status = :status'; $params['status'] = $status; } $sql .=' ORDER By i.createTime DESC'; $query = $this->entityManager->createQuery($sql); $orderList = $query->setParameters($params)->getResult();
2. In mongodb There are actually two pitfalls in the time input and query examples in
:
##
@ ->field('submit_time')->gt(new \DateTime($start)) ->field('submit_time')->lt(new \DateTime($end))Here, for time query, For greater than and less than, an object must be passed.
$query->field('status')->equals($status);Here, mongodb will not help you identify this as an int type by default. What type it is, it must be passed in manually.
$data = array(); if (!isset($startDate)) { throw new \Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } if (empty($endDate)) { $endDate = $startDate; } $startTimestamp = strtotime($startDate); $endTimestamp = strtotime($endDate); if ($startTimestamp > $endTimestamp) { throw new \Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } $start = date('Y-m-d 00:00:00', $startTimestamp); $end = date('Y-m-d 23:59:59', $endTimestamp); $scanner = Order::FROM_TYPE_SCANNER; $query = $this->documentManager ->createQueryBuilder('AppBundle:Order') ->field('submit_time')->gt(new \DateTime($start)) ->field('submit_time')->lt(new \DateTime($end)) ->field('from_type')->equals("$scanner"); if (!empty($status) && in_array($status, array(Order::STATUS_CANCELLED, Order::STATUS_SUBMITTED))) { $status = $status + 0; $query->field('status')->equals($status); } else if (empty($status)) { $status = Order::STATUS_SUBMITTED + 0; $query->field('status')->equals($status); } else { throw new \Exception("参数不正确", BaseException::ERROR_CODE_ILLEGAL_PARAMETER); } $orderList = $query->sort('create_time', 'DESC') ->getQuery() ->execute();Related recommendations:

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
