Now that we have the pointer to the current stock in the linked list we need to turn this stock struct from libstocks into an associative array. Luckily we have macros that make this easy: Symbol, 1); add_assoc_string(return_value, "time", stock_quotes->Time, 1); add_assoc_string(return_value, "date", stock_quotes->Date, 1); add_assoc_string(return_value, "name", stock_quotes->Name, 1); add_assoc_double(return_value, "current", stock_quotes->CurrentPrice); add_assoc_double(return_value, "last", stock_quotes->LastPrice); add_assoc_double(return_value, "open", stock_quotes->OpenPrice); add_assoc_double(return_value, "min", stock_quotes->MinPrice); add_assoc_double(return_value, "max", stock_quotes->MaxPrice); add_assoc_double(return_value, "variation", stock_quotes->Variation); add_assoc_double(return_value, "percent", stock_quotes->Pourcentage); add_assoc_long (return_value, "volume", stock_quotes->Volume); stocks_struct->current = stock_quotes->NextStock;]]> We initialized our return value to be an array, then added a bunch of elements and finally we advanced the pointer to the next element in the link list. That's it. We are done. We don't need to explicitly return anything here. *return_value* is automatically returned. We are ready to compile and test our new extension.
