I'm new to PHP and I have a question regarding handling user input or form validation. I'm currently working on a web application where users will be providing some input through forms. I have been learning about control structures in PHP and I was wondering if I can use them to handle user input or form validation.
I have heard that control structures are used for conditional execution and looping, but I'm not sure if they can be applied to handle user input. I want to make sure that the input provided by the user is valid and meets certain criteria before it is processed further. Can control structures help me achieve this?
I appreciate any guidance or advice you can provide. Thank you in advance for your help!
