UBB.Developers Forums Community Development Programming PHP and Server-side Scripting sorting numbers

@array = sort (@array);

range 0-30

this will sort 0, 10, 11, 12... 19, 1, 20, 21...

thank you

I guess there is a better way, but try:

The proper way is to use the spaceship operator

sort {$a <=> $b} @array;

spaceship operator?

Using it in a sub is better I think;

why? You're doing the exact same thing except adding a call to a subroutine overhead on top of it.

Something like that, where the sub is nothing more than the command, is useless

Yes, spaceship operator is how a lot of people in the perl community refer to <=> since it looks like a spaceship

well.. you can call this sub from another file and use it in every sub, just as a shortcut

IMO ...

I don't know, as that participates under Unix, but the call of XX lasts with me, a Windows calculators, essentially longer...

I have used following code for the testing:

But that's just it...it's a one line sort statement. You aren't saving anything by calling the sort directly, or calling a subroutine and still passing it the array.

You're gaining the overhead of a subroutine call for no added benefit

thanks guys, thanks Mark.
