quick random question about sometin..

[RaythMistwalker]

ok we have ++$variable to increase something by 1.

 

Can we use --$variable to decrease by 1? if not how do we do this?

 

And what if i wanted to decrease by 5 but didnt want to  use 5 lines?

[The Little Guy]

you can do --$variable to decrease

 

to decrease by 5:

$variable -= 5;

 

increase by five:

$variable += 5;
