php - I can't find what *exactly* the syntax error is in mysql

I am creating a simple database and it's table for learning purpose:

This is my php code(script.php)

$sql = file_get_contents("init.sql");

$servername = "localhost";
$username = "root";

$password = "";
  // connect to database
$conn = new mysqli($servername, $username, $password);

if ($conn->connect_error) {
    die("Connection error: " . $conn->connect_error);
}


 if($conn->query($sql) == True){

   echo "Database and Table has been created succesfully!";
 }

 else {
   echo "\nError creating database and table:  . $conn->error";
 }

 ?>

And this is mysql file(init.mysql)

CREATE DATABASE test;
  USE test;

  CREATE TABLE  Users (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),

date_of_registration TIMESTAMP)

The exact error I am seeing is:-

Error creating database and table: . You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'USE test; CREATE TABLE Users ( id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY ' at line 2

In my opinion, the code is syntactically correct but as you see I am getting an error

So I am struggling to find where is the error but no luck :(
Or I am blind enough to see it.

Answer

To process multiple queries in one call (you have three in your file), you need to use multi_query. Change

if($conn->query($sql) == True){

to

if($conn->multi_query($sql) == True){
