When writing Laravel console commands, there are some constants available for return values in the base Symfony command. They make it much easier to see what's happening!

<?php
class MyCommand extends Command
{
    public function handle()
    {
        // Instead of doing this
        return 1;

        // Do one of these instead:
        return self::SUCCESS;
        return self::FAILURE;
        return self::INVALID;
    }
}
