Check if var exist before unsetting in PHP?
php
Solution
Just unset it, if it doesn't exist, nothing will be done.
Problem
With error reporting on, or even for best practice, when unsetting a variable in PHP, should you check to see if it exist first (in this case it does not always exist) and the unset it, or just unset it? ``` <?PHP if (isset($_SESSION['signup_errors'])){ unset($_SESSION['signup_errors']); } // OR unset($_SESSION['signup_errors']); ?> ```
