How To Use Isset In PHP Form

In PHP, we can use a function called “isset()” to check if a variable has been given a value or not. If the variable is not empty, the isset() function will return “true,” and if it is empty, it will return “false.” The isset() function can be helpful when we work with forms because it allows us to check if a field has been filled or not.
