  4. When user click on Submit button after entering all inputs these two attributes bring end users data to Registration.php file.
  5. There first connection.php file executed to create connection with database ‘dbase’. Using if() condition we checking Submit button whether entered by user or not through (isset($_REQUEST['submit'])!='') condition.
  6. If return yes another if() checks every input tag filled with value or null by line ‘$_REQUEST['nm']==''’. Here ‘nm’ denotes html file’s Username input tag by ‘name’ attributes value. Likewise, all input values checked that are filled or null.
  7. If not null, else block executed where insert query executed with values of end user entered data. These are stored to table ‘userlevels’ on respective columns ‘uname,email,pass’.
  8. To execute this query ‘mysqli_query()’ method was defined with parameters of query variable ‘$sql’ and database connection variable $con.
  9. Echo statement will print message as based on your execution result. Instead echo() you can prefer print() method if you want and that not going to affects your result.
