- PHP Master | Inversion of Control - The Hollywood Principle
- Core points The concept of control inversion (IoC) is more broad than dependency injection (DI), which is just a specific application case for IoC that takes advantage of IoC. DI drives class design to adopt external collaborators, provided by the surrounding environment; while IoC transfers responsibilities between components and external environments. IoC, also known as the Hollywood Principle, can significantly help develop scalable, highly decoupled program modules. It allows the external environment to implement all necessary logic, thereby simplifying the implementation of the module. Observer pattern is a classic example of IoC. It allows a highly decoupled body to perform some specific tasks without affecting the surrounding environment, while external observers implement the processing of events triggered by the body

- PHP Master | List Files and Directories with PHP
- This article discusses common tasks in PHP application development: listing files and directories. We will introduce several basic and advanced solutions and analyze their pros and cons. First, we will introduce three ways to use basic PHP functions and then gradually transition to a more powerful way to leverage SPL iterators. For the sake of discussion, we assume that the directory structure is as follows: ---manager | ---user | ---document.txt | ---data.dat | ---style.css |---article.txt |----master.dat |---script.php |---test

- Subtype Polymorphism - Swapping Implementation at Runtime
- Core points Subtype polymorphism in object-oriented design refers to the ability of a system to define a set of contracts or interfaces, and then implement them by different subtypes. This is crucial for designing scalable systems that can consume specific contracts without checking whether the implementer is in the expected type. This article demonstrates the use of subtype polymorphisms by developing an insertable cache component that can be extended to suit user needs by developing additional cache drivers. A key feature of the cache component is its ability to swap different cache drivers at runtime without changing any client code. This is achieved by defining a cache contract that is then followed by different implementations, thus taking advantage of the polymorphism

- Action Automation with MySQL Triggers
- Core points MySQL triggers simplify PHP projects with automated operations such as database queries, file operations, and data processing. They are automatically called before or after actions (insert, update, delete) on the table. Triggers were introduced in MySQL version 5.0.2 and required corresponding permissions to be created. They must have a unique name in the database where they are created and will only be fired when the original SQL statement is executed. Triggers help maintain the integrity of a set of tables, automatically increase or decrease statistical tables when new inserts/deletes, record changes to data within the database, and keep tables synchronized with other tables. MySQL triggers can have a positive impact on the performance of your website and allow developers to write a lot of P

- PHP Master | Adding Text Watermarks with Imagick
- Imagick PHP extension library details: Add text watermark to images This article will explain how to use PHP's Imagick extension library to add text watermarks to images. We will explore a variety of methods, including simple text overlay, creating transparent text watermarks using font masks, and more advanced text tiling techniques. Key points: Imagick is a powerful PHP extension library that can be used to process images, including adding text watermarks. Text watermarking can be achieved by creating an Imagick class instance, reading an image, setting the font properties using the ImagickDraw instance, and then adding text to the image using the annotateImage() method. There are many ways to add text

- PHP Master | Practical Code Refactoring, Part 3 - Extensibility
- Key Points Extensible code follows a reusable, logically clear and well-known pattern, and modular code is often highly scalable. Monomer code may be more efficient but is less scalable, so it may be beneficial to strike a balance between the two. Logical scalability involves using the most logical and common language features for work. For complex solutions, it is recommended to follow standard design patterns as they are easy to understand and take into account future developments. Modular design involves dividing applications into modules, which makes development, expansion and maintenance easier. Each module should combine relevant features and functions. Modules should be self-contained as much as possible and minimize dependencies to simplify debugging and deployment. Decoupling and encapsulation involves separation of functions and methods

- PHP Master | Top 10 PHP Security Vulnerabilities
- Key Points SQL Injection: This is a major security vulnerability in PHP, where an attacker inserts SQL code snippets into your URL or web form. PDO preprocessing statements can be used to prevent such attacks, which separate data from instructions, ensuring that data is treated only as data. Cross-site scripting attack (XSS): XSS attack occurs when malicious code is injected into the output of your PHP script. Such attacks can be prevented by validating and cleaning up user input, ensuring that the input does not contain harmful code. Remote files contain: This involves including external files in your application, which can cause harm if they are corrupted. It is possible to disable allow in php.ini file

- PHP Master | The Null Object Pattern - Polymorphism in Domain Models
- Core points The empty object pattern is a design pattern that uses polymorphism to reduce conditional code, making the code more concise and easy to maintain. It provides a non-functional object that can replace the real object, thus eliminating the need for null value checks. Empty object mode can be used in conjunction with other design modes, such as factory mode creating and returning empty objects, or policy mode changing the behavior of an object at runtime. The potential disadvantage of the empty object pattern is that it may lead to the creation of unnecessary objects and increase memory usage. It may also make the code more complicated because additional classes and interfaces are required. To implement the empty object pattern, you need to create an empty object class that implements the same interface as the real object. This empty object provides a default implementation for all methods in the interface, allowing it to replace the real object. This makes
