//create database
$connection = mysqli_connect("localhost","root","";

Database connection failed:

The order of ur arguments to mysqli_select_db() is wrong. $connection should come before db name.

should be:
mysqli_select_db($connection,"alm"

It's shown clearly from the error msg.

Forget That Mysqli_select_db() i.e cancel it.
and use only
$CONNECTION = mysqli_connect("host","username","password","databasename"; i.e ur database name is within the mysqli_connect()

In this order.

<?php
$hostname ="127.0.0.1";
$dbuser = "root";
$dbpass = "";
$db = "Salemdb";

$con = mysqli_connect($hostname, $dbuser, $dbpass, $db) or die ( 'cannot connect ') ;

// other queries go here 
?>

It can be outside. it depends on what he's trying to achieve.

Noordean is right, mysqli resource is suppose to be the first parameter pass, while the other is dbname.

The mighty PDO.. .
