How can PHP developers ensure that their code works consistently across different environments, such as localhost and a server?

PHP developers can ensure that their code works consistently across different environments by using environment-specific configuration files. By creating separate configuration files for localhost and the server, developers can define environment-specific settings such as database credentials, API keys, and other configuration variables. This allows the code to adapt to different environments seamlessly without manual changes. 

// config.php

$environment = 'localhost'; // Change this to 'server' for the server environment

if ($environment === 'localhost') {
    define('DB_HOST', 'localhost');
    define('DB_USER', 'root');
    define('DB_PASS', '');
    define('DB_NAME', 'my_database');
} else {
    define('DB_HOST', 'server_host');
    define('DB_USER', 'server_user');
    define('DB_PASS', 'server_pass');
    define('DB_NAME', 'server_database');
}

// Use the defined constants throughout the code
$connection = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
