Suppose there is a table named "users" with columns for id$,$ name, age, email, address, and

college. Use PHP to handle the form submission.

You must Validate the input data to ensure that all fields are filled, the email is in a valid

format, and the age is a numeric value.

You must check for duplicate email addresses before insertion to ensure unique entries.

After submission, if the data is successfully inserted into the database, display a

confirmation message.

If there are errors in the form or with the database connection$/$query$,$ display

appropriate error messages.

Comment your code thoroughly to explain each part of the script.

You have to upload the PHP scripts, and any additional file as a rar or a zip file.

No need to write the HTML file. Just write the name of html input fields in the comments
