How can PHP cookies be managed efficiently to avoid redundant or conflicting cookie settings in a web application?

To manage PHP cookies efficiently and avoid redundant or conflicting cookie settings in a web application, it is important to carefully set and update cookie parameters consistently throughout the application. This includes setting the cookie path, domain, and expiration time consistently across all cookie operations to prevent conflicts. Additionally, using a centralized function to handle cookie operations can help ensure that cookie settings are applied uniformly. 

// Centralized function to set cookie with consistent parameters
function setCookieWithParams($name, $value, $expires) {
    $path = '/'; // Set cookie path to root to ensure consistency
    $domain = $_SERVER['HTTP_HOST']; // Set cookie domain to current domain
    setcookie($name, $value, $expires, $path, $domain);
}

// Example usage of the centralized function
setCookieWithParams('example_cookie', 'example_value', time() + 3600); // Set cookie with consistent parameters
