Cut off LAST letter(s)?

Postby Darren » Sat Jun 04, 2005 4:45 am

I'm currently using this bit of PerlCode to take just the first letter of a variable (in this case, $Subject):

Code: Select all
$firstletter = lc $Subject;
$firstletter =~ s/[^A-Za-z0-9\-\.]+//g;
$firstletter = lc( substr($firstletter,0,1) );

My question is, is there such a helpful bit of code that will remove the last two characters from a variable? Data in my $Category variable can be of various lengths, but I want to create a variable that always removes the last two letters from whatever the value is.

Thanks!
Darren

Here's some code that should do it:
Code: Select all
<PerlCode>
$cutvariable = substr($variable, 0, -2);
</PerlCode>
