What is the significance of the FALSE return value in the context of mssql_connect errors in PHP?

The significance of the FALSE return value in the context of mssql_connect errors in PHP is that it indicates a failure to establish a connection to the MS SQL Server database. This could be due to incorrect server credentials, server unavailability, or other network-related issues. To solve this issue, you should double-check the server credentials, ensure the server is running, and troubleshoot any network problems.

<?php
$server = 'server_name';
$user = 'username';
$password = 'password';
$database = 'database_name';

$conn = mssql_connect($server, $user, $password);

if (!$conn) {
    die('Connection failed: ' . mssql_get_last_message());
} else {
    echo 'Connected successfully';
}
?>
