Message:

I'm currently making a hosting panel but I have some problems with the database management. Is there any way to manage(create/edit permissions/delete) mysql users and get a database size(MB) in MySQL using Laravel Eloquent? Currently using Laravel 8, thank you!

My Answer:
Unfortunately, Laravel Eloquent does not have built-in support for managing MySQL users or retrieving database size directly.

To manage MySQL users, you can use Laravel's Database Query Builder or Raw SQL queries to interact with the MySQL `mysql.user` table. Here is an example of how you can create a new MySQL user using Laravel's Database Query Builder:

php
use Illuminate\Support\Facades\DB;

DB::statement("CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password'");
DB::statement("GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'localhost'");
DB::statement("FLUSH PRIVILEGES");


To retrieve the size of a database in MySQL, you can use a raw SQL query to calculate the size of the database. Here is an example of how you can retrieve the size of a database in MySQL using Laravel's Database Query Builder:

php
use Illuminate\Support\Facades\DB;

$databaseName = 'your_database_name';

$result = DB::select(DB::raw("SELECT table_schema 'Database Name', SUM(data_length + index_length) / 1024 / 1024 'Size (MB)' FROM information_schema.TABLES WHERE table_schema = '{$databaseName}' GROUP BY table_schema"));

$databaseSize = $result[0]->{'Size (MB)'};


Please note that managing MySQL users and retrieving database size directly using Laravel Eloquent is not recommended as Eloquent is primarily designed for interacting with database tables and records, not for managing database users or retrieving database metadata. It is better to use raw SQL queries or Laravel's Database Query Builder for these tasks.
