"In this tutorial, we'll learn how to validate form data in PHP using filter_var, preg_match, and empty functions. We’ll validate key fields from the student registration form, such as name, email, phone, age, and gender, ensuring all inputs meet the required standards. If validation fails, we’ll display user-friendly error messages; otherwise, we’ll show the submitted user details. This is the second part of our Student Management System mini-project, continuing from Lecture 21 in the Learn PHP series. 📚 Learn PHP Playlist:https://www.youtube.com/playlist?list=PLN7w5iHU1w8vEneVB4scNAby9Tl5g_yHu 💻 Topics Covered: Validating form data in PHP Using filter_var for email validation Using preg_match for name, phone, and custom patterns Checking for empty fields in PHP Displaying error messages for invalid inputs Processing valid form data Make sure to like, share, and subscribe for more PHP tutorials in the series!
