Where is the code that writes the information to the database?

Use PHP Data Objects (PDO) - just search the net and you get plenty of links including the following:
"https://en.wikibooks.org/wiki/PHP_Programming/PHP_Data_Objects"
PDO makes it easy to work with other DBs too (Oracle and PostGRESql)

write database user name in databse connection query
$conn = mysqli_connect("localhost","root","","logintest");

<?php

include 'dbh.php';

$first = $_POST['first'];
$last = $_POST['last'];
$uid = $_POST['uid'];
$pwd = $_POST['pwd'];

if(isset($_POST['submit']))    
{
  if(mysqli_query($conn,"insert into table_name values('$first','$last','$uid','$pwd')"))
{
  
  echo"data insert";
}
}

?>
