In cases where users are limited to specific database configurations by their hosting provider, what steps can be taken to troubleshoot connection issues in PHP scripts?

If users are limited to specific database configurations by their hosting provider, they may encounter connection issues in PHP scripts. One potential solution is to modify the database connection settings in the PHP script to match the specific configuration provided by the hosting provider. This may involve adjusting the database host, username, password, and database name in the connection string.

<?php
$host = "host_name";
$username = "username";
$password = "password";
$database = "database_name";

$conn = new mysqli($host, $username, $password, $database);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} else {
    echo "Connected successfully";
}
?>
