How does server-side validation differ from client-side validation in the context of file uploads?
- Client-side validation is less secure than server-side validation.
- Client-side validation is performed on the client's browser before the file is uploaded.
- Server-side validation is not applicable to file uploads.
- Server-side validation is performed on the server after the file is uploaded.
Server-side validation is crucial for security as it ensures that uploaded files meet specific criteria, such as file type and size, preventing malicious uploads. Client-side validation can be bypassed, making server-side validation essential for robust security.
In CodeIgniter, the method ________ is used to set custom error and exception handlers.
