How to redirect data from php script to laravel

Step1:Setting the Callback URL:

$paramList["CALLBACK_URL"] = "http://wz-account-admin-ms/api/v1/j/view-laravel/$ORDER_ID/$TXN_AMOUNT/$admin_id/$user_name/$create_date/$org_slug/$EMAIL/$created_date";

In this code, you are constructing a callback URL and storing it in the $paramList array. This URL is created using placeholders enclosed in double curly braces, e.g., $ORDER_ID, $TXN_AMOUNT, etc. These placeholders are expected to be replaced with actual values when this URL is used.

$ORDER_ID, $TXN_AMOUNT, $admin_id, $user_name, $create_date, $org_slug, $EMAIL, and $created_date appear to be variables that will be dynamically replaced with values when constructing the URL.
Step2:Defining a Route:

Route::post('view-laravel/{param1}/{param2}/{param3}/{param4}/{param5}/{param6}/{param7}/{param8}', [App\Http\Controllers\PaymentController::class, 'index'])->name('index');

In this code, a route is defined in Laravel. This route maps to the PaymentController's index method and specifies that it accepts a POST request. The route contains placeholders (e.g., {param1}, {param2}, etc.) which will be used to capture values from the URL.

The route name is set to 'index' for reference.
Controller Method index:

public function index($param1, $param2, $param3, $param4, $param5, $param6, $param7, $param8)
{
    log::info("data");
    log::info($param1);
    log::info($param2);
    log::info($param3);
    log::info($param4);
    log::info($param5);
    log::info($param6);
    log::info($param7);
    log::info($param8);
    // ... (remaining code not included in your provided snippet)
}

This is the index method of the PaymentController. It's configured to receive values from the URL parameters (captured by the route). Inside the method:

It logs the message "data" and each of the received parameters ($param1, $param2, etc.) to Laravel's log, which can be useful for debugging and tracking data.

The code you provided appears to fetch data from a model called addcart based on the value of $param3, then extracts specific columns and stores them in arrays. The remaining code in the method is not included in your snippet, but it is likely responsible for further processing this data.
