How can undefined method errors, such as "Call to undefined method Ice_ObjectPrx::getRegistration()", be resolved when working with PHP and external frameworks like Slice?

To resolve undefined method errors like "Call to undefined method Ice_ObjectPrx::getRegistration()", you need to ensure that the method being called actually exists in the class or object you are working with. In this case, it seems like the method "getRegistration()" is not defined in the Ice_ObjectPrx class. You should check the documentation for the Ice framework or the class definition to see if there is a different method you should be using instead. 

// Check if the method exists before calling it
if (method_exists($iceObjectPrx, 'getRegistration')) {
    $registration = $iceObjectPrx->getRegistration();
    // Do something with $registration
} else {
    echo "Method getRegistration() does not exist in Ice_ObjectPrx class.";
}
