Remove duplicate after union two collections in Laravel 5

Problem: Having two collections/MySQL query results and combine them using union():


then want to remove all duplicate on that union result.

Solution: using unique() to remove duplicates. You can add a parameter like unique(‘id’) to specifically remove which tag name. Example:

$result1 = $result1->unique()->values()->all();

Remember to assign it to a variable or else it will remain the same.

Change localhost to correct domain path in Laravel

Update .env file to update Laravel domain name

and remember to clean config setting by enter below command:

php artisan config:clear

Applying version design in Laravel

Problem: Current Laravel need to serve different companies and have different stage(production, test, etc.)

Using Route::group and create a different folder for different website/stage.

Solution: follow post on this and this:

  1. Create folders for a different purpose and put controller you want inside it

In the UserController.php, remember to change namespace accordingly.

For example for controller under v1 folder

namespace Api\v1;

for controller under v2 folder

namespace Api\v2;

In the web.php, using Route::group to determine using which controller, like:

Route::group(['prefix' => 'api/v1'], function () {
  Route::get('user',      'Api\v1\[email protected]');
  Route::get('user/{id}', 'Api\v1\[email protected]');

Route::group(['prefix' => 'api/v2'], function () {
  Route::get('user',      'Api\v2\[email protected]');
  Route::get('user/{id}', 'Api\v2\[email protected]');

for any prefix like api/v1, using the controller under v1 folder.

Route::group(['domain' => 'itdailydocumentation.com'], function () {
  Route::get('user',      'Api\v3\[email protected]');
  Route::get('user/{id}', 'Api\v3\[email protected]');

for domain itdailydocumentation.com, using controller under v3 folder.

As for the version design for layout, you can also copy the view blade to a different folder:

├── v1/
│   ├── master
|   |   ├── master-public.blade.php
|   |   ├── master-admin.blade.php
|   |   ├── master-user.blade.php
|   ├── views
|   |   ├── home
|   |   ├── chat
|   |   ├── order
|   |   ├── reports
├── v2/
└── v3/

Laravel does not load asset via HTTPS

Problem: After turn on HTTPS, Laravel load the assets via HTTP and it cause Google Chrome inspector to pop up a message “…was loaded over HTTPS, but requested an insecure…

Although you access the page via HTTPS but HTTPS page is asked to load a resource over HTTP. In general, simply change the setting in order to load assets via HTTPS.

Solution: for Laravel check out this post, below changes work for me.

Find AppServiceProvider.php and change boot()

    public function boot()
        If (env('APP_ENV') != 'local') {
            $this->app['request']->server->set('HTTPS', true);


If you are just for testing (local environment), simply change APP_ENV checking:

If (env('APP_ENV') == 'local') {

Laravel composer update failed with carbon extension

Problem: Run composer update failed with a message “providing support and update for 1.x versions, please upgrade to Carbon 2.”

This is because of carbon version 1 is deprecated, you have to use Carbon 2, but Carbon requires Laravel 5.8

Solution: According to the official Carbon website, you can just update composer.json with below content:

    "require": {
        "nesbot/carbon": "2.25.0 as 1.39.0"
        "kylekatarnls/laravel-carbon-2": "^1.0.0"

In this case, you can still be using other versions of Laravel

Change Timezone in Laravel 5

Problem: In Laravel, the created_at and updated_at attribute in database value are incorrect when users trying to create and update data.

Solution: Change the timezone value in /config/app.php. The timezone list can be found at https://www.w3schools.com/php/php_ref_timezones.asp

    | Application Timezone
    | Here you may specify the default timezone for your application, which
    | will be used by the PHP date and date-time functions. We have gone
    | ahead and set this to a sensible default for you out of the box.

    'timezone' => 'Asia/Taipei',

VerifyCsrfToken .php

protected $except = [
'foo', // for route 'foo', this route can post without csrf token
