👉 The webdb.php is where you keep all your boring, mundane data on your website.
An interesting example: Imagine if someone put all of their personal information into a single database that was hosted on the internet. Everyone would have access to this data and could use it for whatever reason they want to. So, imagine if someone used some of your webdb.php data in a prank where they uploaded an ad onto social media. The person who created the ad could then see all their personal information being spread around the world just because they shared that ad on their website. This is just one example, but you get the idea. The webdb.php is like a virtual database filled with your boring data that could be accessed by anyone and everywhere.
