This course equips learners with the essential knowledge and practical skills to develop dynamic, data-driven web applications using PHP and XHTML. Designed for beginners and aspiring web developers, the course guides learners through configuring a local server environment, constructing and executing fundamental PHP scripts, and generating robust XHTML output. Participants will explore how to design and process web forms, manage user input through various HTTP methods, and leverage multiple input types. Emphasis is placed on mastering PHP control structures, including conditional logic, comparison and logical operators, and iterative statements to control program flow and decision-making. By the end of the course, learners will be able to apply core PHP and XHTML concepts, analyze user input and program behavior, and create interactive, server-side solutions for the modern web—all while employing higher-order thinking skills.
