In what scenarios would it be beneficial to use a custom function for typecasting strings in PHP instead of relying on built-in functions like parse_ini_file()?

Using a custom function for typecasting strings in PHP can be beneficial when you need more control over the typecasting process or when you have specific requirements that are not met by built-in functions like parse_ini_file(). By creating a custom function, you can tailor the typecasting logic to fit your needs and handle edge cases more effectively. 

function customTypecast($value) {
    // Custom typecasting logic here
    // Example: typecast string "true" to boolean true
    if ($value === "true") {
        return true;
    } elseif ($value === "false") {
        return false;
    } else {
        return $value;
    }
}

// Example usage
$config = parse_ini_file('config.ini');

foreach ($config as $key => $value) {
    $config[$key] = customTypecast($value);
}

print_r($config);
