Error Handling: Check for cURL errors and handle them gracefully. Array Creation: Used [] instead of array() and simplified array creation. Null Coalescing Operator: Used ?? for safer access to possibly undefined properties. Function Isolation: Split the cURL preparation and search logic into separate functions for clarity. Consistent Naming: Renamed prepare_search_curl_obj to prepareSearchCurlObj for consistency in naming conventions.
