How can I write this code better, or is this method correct?

Hello Laravel Community,

I'm currently working on a Laravel project and have written a piece of code that functions as intended. However, I'm wondering if there's a more stable and efficient way to achieve the same result using Laravel's native methods. I'm looking for insights on best practices and potentially overlooked Laravel features that could enhance the stability and performance of my code.

Here's the code snippet I'm working with:

if ($data['IsSuccessful']) {
	$this->orderHeader->refresh();
                $mevcutErpNo = $this->orderHeader->erp_order_number;
                $this->orderHeader->is_process_run = 1;
                if ($mevcutErpNo != null) {
                    $this->orderHeader->erp_order_number =  $mevcutErpNo . ',' . $data['Data']['FatUst']['FATIRS_NO'];
                    $this->orderLineNew->erp_order_number = $mevcutErpNo . ',' . $data['Data']['FatUst']['FATIRS_NO'];
                } else {
                    $this->orderHeader->erp_order_number = $data['Data']['FatUst']['FATIRS_NO'];
                    $this->orderLineNew->erp_order_number = $data['Data']['FatUst']['FATIRS_NO'];
                }

                $this->orderLineNew->save();
                $this->orderHeader->save();
            }

My questions are: In a scenario I'm working on in Laravel, I need to add comma-separated values to a field and I'm looking for the best way to do this. Here's a brief summary of my scenario:

In my application, I process orders on a per-truck basis. For example, when a customer places an order for 10 items, I need to record this as 10 separate invoices because each truck requires its own documentation. To manage this, when a customer orders 10 items, I use Horizon to send the header and line to the ERP 10 times and record them in the database. However, in the customer panel, I display the order as a single entry. I store the document numbers in a field named erp_order_number, separated by commas. Each time, I check if there is data in the erp_order_number field before adding a new one, and if there are multiple items, I add a comma to the end of the invoice number. I repeat this process as many times as the number of orders, which in this example is 10 times.

My current code works, but I want to optimize it. I'm looking to find out if there's an existing function, interface, or a native solution in Laravel that could make this process more efficient. Something similar to the "Laravel ShouldDispatchAfterCommit" interface, for example.

Any suggestions or guidance on how to more effectively handle this scenario in Laravel would be greatly appreciated.

Thank you in advance!
