What steps should be taken to set the correct path to the PostgreSQL database in PHP?

To set the correct path to the PostgreSQL database in PHP, you need to specify the host, database name, username, and password in the connection string using the `pg_connect()` function. Make sure the PostgreSQL extension is enabled in your PHP configuration.

$host = 'localhost';
$database = 'your_database_name';
$user = 'your_username';
$password = 'your_password';

$conn = pg_connect("host=$host dbname=$database user=$user password=$password");
if (!$conn) {
    die('Could not connect to the database');
}
