What are common pitfalls when downloading tutorials in PHP?

One common pitfall when downloading tutorials in PHP is outdated or deprecated code. To avoid this issue, always check the version of PHP the tutorial is using and make sure it is compatible with your current version. Additionally, be cautious of tutorials that may contain security vulnerabilities or bad coding practices. 

// Example of checking PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    die('This tutorial requires PHP 7.0 or higher');
}
