Differences between MySQL and MySQLi
When developing web applications with PHP and MySQL databases, you have the option to use either the older MySQL extension or the more modern MySQLi (MySQL Improved) extension.
MySQLi
MySQLi
Introduction to MySQLi
MySQLi, which stands for MySQL Improved, is a relational database driver used in PHP to interact with MySQL databases. It offers enhanced features and capabilities compared to its predecessor, the MySQL extension.
Object-Oriented Programming (OOP)
OOP Best Practices
Object-Oriented Programming (OOP) in PHP offers a structured way to manage code, making it easier to maintain and extend. However, to fully leverage OOP, adhering to best practices is crucial. This article will delve into essential best practices for PHP OOP, including class naming conventions, method naming conventions, and code organization.
Object-Oriented Programming (OOP)
PHP Reflection API
The Reflection API in PHP provides powerful tools for introspection, allowing developers to examine and manipulate classes, interfaces, functions, methods, and extensions. This feature is particularly useful for debugging, dynamic code analysis, and building advanced frameworks or libraries.
Object-Oriented Programming (OOP)
Anonymous Classes
Anonymous classes, introduced in PHP 7, are a powerful feature that allows developers to define classes without giving them explicit names. This can be particularly useful for creating one-off objects, reducing boilerplate code, and simplifying class hierarchies.
Object-Oriented Programming (OOP)
Late Static Binding
Late Static Binding (LSB) in PHP is a feature introduced in PHP 5.3 that addresses some limitations of early static binding. Early static binding refers to the process where the scope of static references is resolved at compile time, meaning that when a static method is invoked, the method called is determined by the class that initially defined it.
Object-Oriented Programming (OOP)
Object Cloning
Object cloning is a fundamental concept in object-oriented programming, allowing developers to create copies of objects. In PHP, object cloning can be performed using the clone keyword, which creates a shallow copy of the object.
Object-Oriented Programming (OOP)
Object Serialization
Serialization is a process of converting an object into a format that can be easily stored or transmitted and later reconstructed. In PHP, serialization allows you to convert objects into a string representation that can be saved to a file, database, or sent over a network, and later converted back into the original object.
Object-Oriented Programming (OOP)
PHP SOLID Principles
The SOLID principles are a set of five design principles intended to make software designs more understandable, flexible, and maintainable. These principles, when followed, help in creating code that is easier to manage and extend over time.
Object-Oriented Programming (OOP)
Abstraction in PHP
Abstraction is a fundamental concept in Object-Oriented Programming (OOP) that allows developers to focus on the essential features of an object without getting bogged down by the details. It helps in managing complexity by hiding the intricate details and exposing only the necessary parts of the object.
