How can PHP version differences impact the syntax and best practices for object-oriented programming in PHP?

PHP version differences can impact object-oriented programming in PHP by introducing new features, deprecating old ones, or changing syntax. To ensure compatibility and adhere to best practices, developers should always check the PHP version requirements for their codebase and adjust their syntax accordingly. This may involve using polyfills or alternative approaches to achieve the same functionality across different PHP versions. 

// Check PHP version before using certain features
if (version_compare(PHP_VERSION, '7.0.0', '>=')) {
    // Use new syntax or features for object-oriented programming
} else {
    // Implement polyfills or alternative approaches for compatibility
}
