What are the potential pitfalls of sending POST data via GET in PHP scripts, and how can they be avoided?

Sending POST data via GET in PHP scripts can expose sensitive information, as GET requests append data to the URL, which can be easily accessed and viewed by users. This can lead to security vulnerabilities, such as data leakage and potential manipulation. To avoid this, always use POST requests when sending sensitive data, and ensure that any form submissions or data transmissions are handled securely.

   <input type="submit" value="Submit">
</form>
