Server-side validation is a crucial part of web development that involves validating user input on the server before processing it. This type of validation helps ensure data integrity, security, and consistency in the application. By performing server-side validation, developers can prevent malicious attacks, data manipulation, and ensure that only valid data is accepted and processed.

In server-side validation, input data sent by users through forms or requests is validated on the server side using programming languages like PHP, Python, Java, or Node.js. This process involves checking the data against predefined rules, such as required fields, data formats, length constraints, and more. If the input data does not meet the specified criteria, appropriate error messages are generated and sent back to the user interface for display.

Implementing server-side validation is essential for creating robust and secure web applications, as it complements client-side validation done using JavaScript. By combining both client-side and server-side validation techniques, developers can create a more reliable and user-friendly web experience while safeguarding the application against potential threats and vulnerabilities.
