What are the potential pitfalls of using different PHP versions on local and web servers?

Using different PHP versions on local and web servers can lead to compatibility issues and unexpected behavior in your code. To avoid this problem, it's important to ensure that the PHP version on your local development environment matches the version used on your web server. This will help you catch any potential issues early on and ensure a smooth deployment process. 

// Example code snippet to check PHP version compatibility
$local_php_version = phpversion();
$web_server_php_version = "7.4.0";

if ($local_php_version !== $web_server_php_version) {
    echo "Warning: PHP versions do not match. Please update your local environment to match the web server version.";
}
