Here is the code
<?php
$servername = "localhost";
$usrname = "root";
$pwd = "";
$db = "test_db";
// connect to the database
$conn= mysqli_connect($servername, $usrname, $pwd,$db);
if (!$conn){
die('connection failed' . mysqli_connect_error());
}
// Create database
$sql = "CREATE DATABASE IF NOT EXISTS test_db";
if (mysqli_query($conn, $sql)) {
echo "Database created successfully<br>";
} else {
echo "Error creating database: " . mysqli_error($conn);
}
?>
I am not sure what is going on as I am sure i made no errors while typing. As it keeps showing me that there is an unknown database despite the fact i made a CREATE DATABASE statement.
I do not know if there is something else i need to do but by all measures the code should work.
It is supposed to echo the "Database created successfully" or the error message.

How do I create a database if it doesn’t exist, using PHP?
$conn= mysqli_connect($servername, $usrname, $pwd,$db);
You are trying to connect to a database that did not initially exist, so you get a fatal error.
Try creating new database using try catch blocks
Your code is fine, You just have to remove $db from mysqli_connect().
Because you are requesting to connect "test_db" to this database which already not exists.
