What is the significance of using constants for paths in a config file versus dynamically passing them in the constructor?

Using constants for paths in a config file provides a centralized location to manage and update all paths in a project. It ensures consistency and reduces the risk of errors due to typos or incorrect paths. On the other hand, dynamically passing paths in the constructor can lead to scattered path definitions throughout the codebase, making it harder to maintain and troubleshoot. 

// Define constants in config file
define('CONFIG_PATH', '/path/to/config/');
define('LOG_PATH', '/path/to/logs/');

class MyClass {
    private $configPath;
    private $logPath;

    public function __construct() {
        $this->configPath = CONFIG_PATH;
        $this->logPath = LOG_PATH;
    }
}
