Introduction to Object-Oriented PHP
Object-oriented programming (OOP) is a powerful paradigm for building modular, maintainable, and scalable software solutions. In PHP, OOP enables developers to create classes, which are blueprints for objects, and leverage concepts such as inheritance, encapsulation, and polymorphism to create robust and flexible applications.

Embedding in HTML
PHP and HTML are two fundamental technologies for building dynamic web applications. PHP, a server-side scripting language, allows developers to generate dynamic content, interact with databases, and handle form submissions. HTML, on the other hand, is the standard markup language for creating web pages.

PHP File Uploads
File uploads are a common requirement in web applications, allowing users to upload images, documents, and other files to the server. In PHP, handling file uploads involves managing the process of receiving files from the client, storing them securely on the server, and processing them as needed.

PHP Form Validation
Form validation is a critical aspect of web development, ensuring that user-submitted data meets specified criteria before processing. In PHP, form validation can be performed both on the client-side and the server-side to enhance user experience and maintain data integrity.

PHP Handling Forms
Forms are essential elements in web development, facilitating user interaction and data submission. In PHP, handling form submissions is a common task, allowing developers to process user input, validate data, and perform various actions based on user interactions.
PHP
Regular Expressions
Regular expressions (regex) are powerful tools for pattern matching and string manipulation. In PHP, regular expressions enable developers to perform complex text processing tasks efficiently.
