How important is it to have knowledge and understanding of server management when updating PHP versions?

It is crucial to have knowledge and understanding of server management when updating PHP versions because different PHP versions may have different requirements and configurations. Without proper server management knowledge, updating PHP versions can lead to compatibility issues, security vulnerabilities, and performance issues. 

// Example of checking PHP version before running code
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    echo 'This code requires PHP 7.0 or higher';
    exit;
}

// Your PHP code here
