Configure Database Connections Automatically base on Environment - php

Question

I know this is so wrong, but I've tried google for this kind of task, and I found nothing.
Goal
I'm trying to make an if check, base on my Laravel environment, I will set the database connection appropriately between my local environment and my Heroku production environment.
connections' => [
'mysql' => [
'driver' => 'mysql',
if(env('APP_ENV') == 'local'){
'host' => env('DB_HOST'),
'database' => env('DB_DATABASE'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
'unix_socket' => env('UNIX_SOCKET'),
}else{
'host' => parse_url(getenv("DATABASE_URL"))["host"],
'database' => substr(parse_url(getenv("DATABASE_URL"))["path"], 1),
'username' => parse_url(getenv("DATABASE_URL"))["user"],
'password' => parse_url(getenv("DATABASE_URL"))["pass"],
}
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
]
],

Answer 1

you can define another connection, named for exmaple mysql-heroku, and then in your models you can do protected $connection = (env('APP_ENV') == 'local') ? 'mysql' : 'mysql-heroku';.

Answer 2

Sounds like the Cascading config package would work great for you. Laravel 4 had something very similar to that package.
You can have a config.local folder and config.production folder for your Heroku environment.
Example folder configuration
config/ (production)
├── database.php
config.local/ (local)
├── database.php
config/database.php (production)
...
connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => 'Heroku Host',
'database' => 'Heroku Database',
'username' => 'Heroku Username',
'password' => 'Heroku Password',
'unix_socket' => 'Heroku Socket',
],
],
...
config.local/database.php (local)
...
connections' => [
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST'),
'database' => env('DB_DATABASE'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
],
],
