Server-side validation occurs where the validation and processing of user requests require the response from the server. To understand it more clearly, the user’s input is being sent to the server and validation is done using server-side scripting languages such as PHP, Asp.NET, etc.
After the validation process, feedback is sent back to the client in the form of a dynamically generated web page.
When compared to the Client-Side validation process, the Server-side validation process is more secure because here application is protected against malicious attacks and users can easily bypass client-side scripting language.
