How can error reporting in PHP help troubleshoot issues related to setting and checking cookies?

When setting or checking cookies in PHP, errors can occur due to various reasons such as incorrect syntax, server configuration issues, or browser restrictions. To troubleshoot these issues, enabling error reporting in PHP can help identify the specific error messages that can guide in resolving the problem effectively. 

// Enable error reporting to display any errors related to setting or checking cookies
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Example code for setting a cookie
setcookie("user", "John Doe", time() + 3600, "/");

// Example code for checking a cookie
if(isset($_COOKIE["user"])) {
    echo "Welcome back, " . $_COOKIE["user"];
} else {
    echo "Cookie not set";
}
