When using PHP's mysqli extension for database operations, we often use preprocessing statements to improve security and execution efficiency. mysqli::stmt_init() is a common starting point for creating preprocessing statement objects, but have you ever encountered such a situation:

In PHP development, it is often necessary to encode and decode data, especially when it comes to network transmission or file storage. json_decode() is a common function to parse JSON data into PHP arrays or objects, while the pack() function can package data into binary strings for easy transmission and storage. This article will explain in detail how to package the array results obtained by json_decode() into binary data using pack().

session is an important mechanism for managing user status. To better debug or monitor user sessions, sometimes we want to automatically log related logs when the session is closed. PHP provides a convenient function session_register_shutdown(), which allows us to register a callback function, which will be executed when the session is closed. This article will demonstrate how to implement a simple session logging system using this function.

In PHP project development, we often use define or const to define constants. As the project continues to expand, the number of constants will also increase dramatically. Over time, some constants may be forgotten and no longer referenced by any code. These unused constants increase maintenance costs and reduce code readability and maintainability. In order to improve the quality of the code, we can use the get_defined_constants function combined with static analysis methods to identify and clean unused constants.

This article offers a comprehensive guide on how to use JSON data in PHP, including converting arrays to JSON strings, parsing JSON into arrays, and real-world use cases for frontend-backend communication. It helps developers manage data formats more efficiently.

In PHP development, connecting to a remote database is a common but error-prone operation. When connecting to a remote database using connect() or similar functions (such as mysqli_connect(), PDO), you need to pay attention to a series of security, performance and configuration-related issues. This article will analyze in detail several aspects that should be focused on when connecting to remote databases using PHP.

In web development, handling time and date-related functions is a very common requirement. If you want to implement a service in Laravel that querys sunset times by city, you can implement it by encapsulating the date_sunset() function. Laravel provides powerful scalability, making modularizing such features very simple. In this article, we will explain step by step how to implement this function.

When developing WordPress plug-ins, we often need to provide dynamic content based on the user's geographical location, such as sunrise and sunset times. PHP's own date_sunset() function can easily calculate sunset time. However, to display the user's "local" sunset time in real time, some positioning technology is needed. This article will take you to implement it step by step, embed date_sunset() in the WordPress plug-in and dynamically display the sunset time.

This article provides a comprehensive guide on implementing data backup and recovery using PHP and Redis, covering both RDB and AOF methods. It's designed for developers and DevOps professionals who need reliable data protection solutions.

This article introduces in detail how to use PHP to develop custom modules in SuiteCRM, including key steps such as module creation, field definition and database operation, to help developers flexibly expand system functions and realize business customization.

The date_sunset() function can be used to get the sunset time at a specified location. By using this function, we can easily compare sunset times for multiple cities and present them in order. This article will explain how to obtain sunset times in different cities through PHP and arrange these times in order from morning to night.

The automatic light control system is a smart home device that can automatically adjust the light switch according to changes in ambient light. In order to improve the intelligence of light control, many systems use astronomical calculation functions to judge the sunset time and control the light's turn on and off based on this moment. date_sunset() is a very practical function in PHP that helps developers get the sunset time of the current geographical location.

When developing calendar applications or weather forecasting functions, we often need to display the sunset time every day.

This article will teach you how to use PHP to get the next 7 days of sunset times and is suitable for displaying directly on the calendar.

When programming in PHP, the date_sunset() function is a common tool that calculates sunset time based on specified dates and geographic locations. Is the calculation of this function accurate? To verify its accuracy, we can compare the calculation results of the date_sunset() function with the sunset time provided by NASA. This article will show how to write code in PHP, get sunset times and compare them with NASA official data.
