How can debugging techniques be applied to resolve issues with setting cookies in PHP?

To resolve issues with setting cookies in PHP, you can use debugging techniques such as checking for syntax errors, ensuring the cookie is set before any output is sent to the browser, and verifying the cookie parameters are correctly configured. Additionally, you can use tools like var_dump() or print_r() to inspect the cookie values.

// Set cookie with debugging techniques
setcookie('cookie_name', 'cookie_value', time() + 3600, '/');
