Need Help??

$array[int(rand(scalar(@array)))];

Of course you can just write

$array[rand @array];
[download]

which will do exactly the same thing and is a bit less distracting to read.

I saw that in another post. Do you know why this is? It seems like rand is unlikely to pick an integer, and `$array[3.14159]` seems nonsensical, but I tried it and it works...	[reply] [d/l]
