What are the implications of PHP version compatibility when working with Facebook API integration?

When working with Facebook API integration, it is crucial to ensure that your PHP version is compatible with the API requirements. This is because newer versions of PHP may have deprecated functions or syntax that could cause issues with the API calls. To solve this problem, you should check the Facebook API documentation for the recommended PHP version and update your server accordingly.

// Check PHP version compatibility with Facebook API
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    die('Your PHP version is not compatible with the Facebook API. Please upgrade to PHP 7 or higher.');
}
