Updating Mysql Database with Php (Help) (Solved!)

[RecklessFlamingo]

Friends, in my MySQL database I have a table named settings which includes fields such as id, title, baseUrl, description, keywords, logo, and fav. The baseUrl, logo, and fav fields should be in URL format. Now my question is: How can I edit these data from the admin panel using PHP? I have searched online a lot but couldn't find a satisfactory solution. It would be greatly appreciated if someone could explain it to me. Thank you.
