Hi and welcome to the course. This course will teach you everything you need to know in order to deliver your message clearly,and will teach you what you need to know about interpersonal communication.What is interpersonal communication? Interpersonal communication is the main process through which people receive and deliver information and messages to one another. In order to succeed in that it’s not enough to phrase messages and present them in a clear way so that people will understand them, but you also need to make people want to listen.Good interpersonal communication is a two way process, which is about sending accurate messages to others and right interpretation of what others are saying to you. Leaving the right impression is a meaningful part in good communication.This course will guide you through understanding the process of communication and give you secrets you need to understand in order to communicate successfully, so that you can:Get greater cooperation from people.Have less situations of misunderstanding.Have people listen to your ideas.Be someone that is worthwhile listening to.Be more accurate and systematic.Increase your ability to think logically.Feel confident and in control of your actions.My name is Asaf and I've been a lawyer for the decade.

Security is one of the most critical aspects of web development — yet it is often overlooked by beginners when learning PHP. The truth is, even a small mistake in your code can open the door for attackers to steal sensitive data, compromise user accounts, or take full control of your application. That’s why I created this course: PHP for Beginners: The Complete PHP Security Course 2025.This course is designed to give you a step-by-step guide to securing your PHP applications, even if you are just starting out. You’ll not only learn how hackers exploit insecure PHP code, but also how to defend against real-world attacks. We’ll cover everything from SQL Injection and Cross-Site Request Forgery (CSRF), to session fixation, secure file uploads, and safe error handling.Through practical examples, I’ll show you exactly how these attacks work and how to fix them. You’ll practice using prepared statements to secure your database queries, hashing and verifying passwords with PHP’s modern password functions, and configuring PHP for a production environment. You’ll also learn how to protect your application at the server level using .htaccess rules, directory restrictions, IP-based protection, and HTTPS enforcement.By the end of this course, you will have the knowledge and confidence to write PHP code that is not only functional, but also secure and production-ready. Whether you are building your first web project, working on an eCommerce site, or managing client applications, the skills you learn here will help you protect both your users and your reputation.If you’re serious about becoming a PHP developer in 2025, security is no longer optional — it’s a must. Enroll today and take the first step toward building safe, professional, and secure PHP applications.

Are you ready to take your PHP skills to the next level? If you've been writing basic PHP scripts using procedural code and want to learn how to write more organized, reusable, and professional-grade applications, this course is for you.This course is a complete introduction to Object-Oriented Programming (OOP) in PHP, carefully designed for beginners and self-taught developers who may have little or no experience with OOP. You'll be guided step-by-step through the essential concepts that form the foundation of object-oriented programming, helping you truly understand not just how to write object-oriented code — but why it matters.We’ll begin with the fundamentals of classes and objects, and you’ll quickly move on to learning about properties, methods, constructors, and visibility (public, private, protected). From there, we’ll explore powerful features like inheritance, method overriding, polymorphism, and encapsulation, showing how they can simplify complex applications and reduce code duplication.You’ll also learn how to use abstract classes, interfaces, and traits to write flexible, extendable code that’s easier to maintain. Along the way, you'll gain clarity on how OOP promotes better code organization by separating responsibilities across well-defined objects.The course will also cover namespaces, autoloading using PSR-4, and how to structure your application folders in a modern way. These skills are essential if you plan to work on larger projects or eventually dive into PHP frameworks like Laravel or Symfony.Every topic is explained in simple, beginner-friendly language, with plenty of practical examples to reinforce your understanding. You won’t just memorize syntax — you’ll learn how to think in objects, break down a problem into logical components,
