How can error logs be used to troubleshoot issues related to setting cookies in PHP?

When troubleshooting issues related to setting cookies in PHP, error logs can be used to identify any errors or warnings that may be occurring during the cookie-setting process. By reviewing the error logs, developers can pinpoint the specific issue causing the problem, such as incorrect syntax or conflicting headers. Once the issue is identified, it can be addressed by adjusting the code accordingly. 

// Set a cookie with an expiration time of 1 hour
setcookie("user", "John Doe", time() + 3600);

// Check for any errors or warnings in the error log
error_log("Setting cookie for user");

// Retrieve the cookie value
$user = $_COOKIE['user'];
echo "Welcome back, $user!";
