What are some best practices for error handling when reading values from an INI file in PHP?

When reading values from an INI file in PHP, it is important to handle errors gracefully to prevent unexpected behavior in your application. One best practice is to check if the file exists before attempting to read it, and to handle any errors that may occur during the reading process, such as invalid file format or missing sections/keys. 

// Check if the INI file exists
$ini_file = 'config.ini';
if (!file_exists($ini_file)) {
    die("Error: INI file not found");
}

// Read the INI file and handle any errors
$config = parse_ini_file($ini_file);
if ($config === false) {
    die("Error: Unable to parse INI file");
}

// Access specific values from the INI file
$database_host = $config['database']['host'];
$database_user = $config['database']['user'];
$database_pass = $config['database']['pass'];
