Thank you for your contribution @kibria365.
We have been reviewing your contribution and suggest the following points below:

• We suggest you put comments in your code, it's very important to your readers.
• Put your code ident, makes it easier to read the code.
• The title of the tutorials are very important. Put keywords that you will use in your tutorial, such as PHP, MySQL and Steem.
• Use better naming of variables, for example these don't make much sense: $a1, $a2, $u, $c, $c2 and $c3

$a1 = date("ymd", time());
$a2 = rand(100,999);
$u = substr(uniqid(), 7);
$c = chr(rand(97,122));
$c2 = chr(rand(97,122));
$c3 = chr(rand(97,122));

• Better detail your tutorial for readers to realize all the concepts you will use.

Your tutorial is very interesting. We look forward to seeing the development of your online Lotto web application.
