This article delves into common problems when submitting HTML form data to PHP scripts, particularly conflicts arising from form elements sharing the same name attribute. Through analysis of a typical example—where a select box and submit button with identical names cause the website_string value to be overwritten—we explain the workings of the $_POST array, form element naming conventions, and data flow mechanisms. We refactor the original code, fix syntax errors, and demonstrate how to correctly receive and process form data in PHP, while emphasizing the importance of input validation and security handling.

This article explores the security differences between HTTP GET and POST methods, based on technical Q&A data, analyzing their impacts on network transmission, proxy logging, browser behavior, and more. It argues that from a network perspective, GET and POST are equally secure, with sensitive data requiring HTTPS protection. However, GET exposes parameters in URLs, posing risks in proxy logs, browser history, and accidental operations, especially for logins and data changes. Best practices recommend using POST for data-modifying actions, avoiding sensitive data in URLs, and integrating HTTPS, CSRF protection, and other security measures.
