Changing PHP CLI memory limit on the fly

There are some tasks in laravel that a php artisan
would just be enough.
But there are tasks that would just consume the php config memory_limit
.
You can always update your php.ini
file and increase the memory_limit=1G
for example or you can do this in your cli
:
1 | php -d memory_limit=1G heavy_script.php |
or
1 | php -d memory_limit=1G artisan command:name |
Cheers!
