Here is my .env file :
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8080
DB_DATABASE=sample_server
DB_USERNAME=root
DB_PASSWORD=
Here is my database.php :
'default' => env('DB_CONNECTION', 'mysql'),
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'url' => env('DATABASE_URL'),
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
'foreign_key_constraints' => env('DB_FOREIGN_KEYS', true),
],
'mysql' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '8080'),
'database' => env('DB_DATABASE', 'forcity_server'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',

'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
]
I tried to find solution and got solution from here but still it's not working. I applied same on local database.

Answer 1

I updated to laravel 6, so I updated PHP because laravel 6 uses 7.2+
by default there wasn't php.ini and when generated, extension was off so I tried migration too and found out this
Check php.ini, there is one row
;extension=pdo_mysql
make it
extension=pdo_mysql
save and restart apache
