In what situations should developers be cautious about relying on assumptions about server configurations when troubleshooting PHP script issues?

Developers should be cautious about relying on assumptions about server configurations when troubleshooting PHP script issues, as different servers may have different settings, versions of PHP, or extensions installed. This can lead to unexpected behavior or errors in the script. It is important to thoroughly test the script on different server configurations to ensure compatibility. 

// Example code snippet to check for a specific server configuration before executing code
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    echo "This script requires PHP 7.0 or higher. Please upgrade your PHP version.";
    exit;
}

// Rest of the PHP script that requires PHP 7.0 or higher
