What are the potential pitfalls of downgrading PHP versions on SUSE 8.2?

Downgrading PHP versions on SUSE 8.2 can lead to compatibility issues with existing code that relies on features or functions only available in newer versions. It may also introduce security vulnerabilities that were patched in newer releases. To mitigate these risks, thoroughly test all applications after downgrading PHP and consider updating code to be compatible with the older version. 

// Example code snippet to check for PHP version before using a specific feature
if (version_compare(PHP_VERSION, '7.0.0', '>=')) {
    // Code that relies on PHP 7.0 features
} else {
    // Code that will run on older PHP versions
}
