XHTML is a markup language that provides structure and semantics to web pages. It is based on XML and is more strict than HTML. XHTML pages must have a document type definition, html and head tags, and a body where the visible content goes. Common XHTML tags include paragraphs, lists, links, images, and divisions to logically separate content. While XHTML provides structure, CSS is used to style pages and control visual presentation through rules that target specific XHTML elements.
Hello Friends..Welcome again.

XML is a markup language which is used for storing and exchanging data. A markup language marks up the text syntactically in a document under different tags and hence makes the text distinguishable. XML stores data in the form of a structured document; these documents are used for creating web pages and for transporting data.

Web standards are the formal, non-proprietary standards and other technical specifications that define and describe aspects of the World Wide Web. In recent years, the term has been more frequently associated with the trend of endorsing a set of standardized best practices for building web sites, and a philosophy of web design and development that includes those methods.
HTML and XML are markup languages that have their own unique features. Both these programming languages are machine- and user-friendly. They have a set of standard words based on syntactical rules of the language.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
