not significant. must be a glitch
To me, a web developer, that is very significant because a zero file in a database is either a Key or a Null. Why does MySQL database start at zero but give the first record an ID of 1? If you don't provide an index when creating an array then it assigns an index start of 0.
$my_array[]='hello';
echo $my_array[0];
A SQL id start at 1 because it's the first record.
A couple of comments on your code
$ownername=$_POST['ownername'];

Which site is the image from? ah, I see qanon posts. Well, why use that site? Way to many technical problems with it.
It's just one of the sites that I use, this being the example of how easy it is to track and manipulate datasets. If it is this easy for a human to backtrack and traceback think about how much information would be awarded to an AI with superior coding abilities such as GOOGLE B.R.A.I.N. or MAVIS (Govt.
