This article provides a detailed guide on how to split SQL structures in PHP projects. By encapsulating SQL statements and creating execution functions, it improves code readability and maintainability, helping developers manage complex database operations with ease.

This article explains three main methods to prevent SQL injection in PHP development, including the use of prepared statements, escaping special characters, and filters, along with two implementation choices to help developers enhance database security.

This article provides a detailed guide on how to prevent common web security vulnerabilities—XSS attacks and SQL injection—using PHP. It includes practical code examples and best practices to help developers improve website security.

This guide provides a detailed explanation on how to configure SQL and PHP in a CentOS environment, covering PHP and MariaDB installation, database security configuration, PHPMyAdmin setup, and more. It helps developers quickly build an efficient and secure development environment.

This article explains how to use Laravel's logging system and PDO extension to monitor and record the last executed SQL query within your application, which is useful for debugging and development.

This article provides a detailed walkthrough of using DVWA for hands-on PHP and SQL injection testing. It helps developers and security professionals understand attack techniques and defense strategies to enhance web application security.

In PHP, using the mysqli_stmt::__construct constructor can create a preprocessed statement object, which can perform SQL queries more safely and efficiently, especially when facing complex SQL statements. This article will introduce in detail how to use mysqli_stmt::__construct and its related methods to implement practical techniques and applications in complex SQL queries to improve the performance and security of the code.

PDOStatement::fetchColumn is a method provided by PDO specifically for retrieving a single column from a result set. Unlike other fetch methods, fetchColumn returns only the first column of the query result, making it particularly useful for queries like SELECT COUNT(*) or when fetching a single field.

When developing cross-platform applications, it is crucial to understand the differences between operating systems. Fortunately, PHP provides the php_uname() function, which can help us gather detailed information about the operating system and environment. We can use this function to build an automated cross-platform difference report script, allowing us to better adapt to various operating system environments.

In PHP development, using mysqli to extend the operation of databases is a common and efficient way. Especially after we perform the insert operation, we usually use $mysqli->insert_id to get the auto-increment ID of the newly inserted record. However, although $insert_id itself does not cause SQL injection problems, it is still crucial to prevent SQL injection throughout the process of inserting data.

In PHP development, many beginners struggle with user input handling. The addcslashes() function might seem like a solution, but there are better, more secure ways to prevent SQL injection. In this article, we will discuss how to use prepared statements and parameter binding for secure database queries.

Monitoring the execution status of SQL queries is crucial for debugging and optimizing PHP applications. This article explains how to use the mysqli::$info function to track SQL execution in real time, providing detailed insights into affected rows, warnings, and other query information.
