Split IP address. 3

[roycrom]

I have this simple piece of code

#!/usr/bin/perl -W
print "Content-type: text/plain\n\n";
my ($a,$b,$c,$d) = split(/./, $ENV{'REMOTE_ADDR'});
print "A is $a\nB is $b\nC is $c\nB is $d\n";
print "$ENV{'REMOTE_ADDR'}";

This gives the ouptut in web page
A =
B =
C =
D =
192.168.0.2

Why aren't the variables being set?
Is there another line with an array I need to use, with an @ARRAY?

Thanks for any help you can give.

try /\./ instead of /./

Thanks alot,

I thought I had it right but didn't realise I had to escape the full stop.

Greatly appreciated

No problem gets me every time.

We should just say for other people reading this thread that.... (should have done this originally)

split - splits up a variable into chunks based upon the pattern between the / characters

/\./ - this pattern means split up the variable between the . characters in it.

and finally - the thing that didn't work /./ had a problem because the . character has a special meaning inside a pattern (it matches any single character) so it needs to be "escaped" with a \ so that split knows you really do mean a . character.

Yeah - and the equal, and opposite, evil is to document and explain so much and so clearly that the actual answer is hidden in the explanations Not that I'd ever do that, obviously.
