How can one effectively debug and troubleshoot errors related to object types in PHP applications interfacing with external systems like CRM and ERP?

To effectively debug and troubleshoot errors related to object types in PHP applications interfacing with external systems like CRM and ERP, you can start by checking the data being passed between the systems to ensure it matches the expected object types. Additionally, review the documentation of the external systems to understand their data structures and object requirements. Utilize PHP debugging tools like var_dump() or print_r() to inspect the object types and data being transferred for any inconsistencies or mismatches.

// Example code snippet to debug and troubleshoot object type errors in PHP applications

// Check the data being passed between systems
var_dump($data);

// Review documentation of external systems
// Ensure data matches expected object types
if ($data instanceof CRM_Object) {
    // Process data for CRM
} elseif ($data instanceof ERP_Object) {
    // Process data for ERP
} else {
    // Handle other object types
}
