Re: Search for abcNUMBERdef, make it a variable, then do math?

make it a variable, for example $12345

Not sure why you would want to, but you cannot create a variable starting with a numeric explicitly, you would have to have 12,345 capturing parentheses groups.

I'm not certain what it is you want, but would this do?

#!/usr/bin/perl 

use warnings;
use strict;

my %nums;
@nums{qw(today yesterday this last)} = undef;
my $alts = join('|',keys %nums);

while (<DATA>) {

    /($alts)(\d+)\1/;
    $nums{$1} = $2;

}

for my $key (keys %nums) {
    my $ans = ($nums{$key} * 0.4)/100;
    print "$key: $ans (from $nums{$key})\n"
}

__DATA__
Today: today408today
Clicks: 34
Yesterday: yesterday555yesterday
Clicks: 61
This Month: this11360this
Clicks: 812
Last Month: last5350last

`I'll try that out and post back. I'm just trying to change Today: today408today Yesterday: yesterday555yesterday This Month: this11360this Last Month: last5350last in to Today: 1.63 Yesterday: 22.22 This Month: 45.44 Last Month: 21.40 40% of what the number is, with the period added. By doing this math for each of them. For example... Today: today408today would do 408*.4/100=1.63200 with the '200' part taken off.` [download]	[reply] [d/l]

`Prototype mismatch: sub main::head: none vs ($) at stats.cgi line 19` See CAVEAT in the LWP::Simple docs: Note that if you are using both LWP::Simple and the very popular CGI.pm module, you may be importing a head function from each module, producing a warning like "Prototype mismatch: sub main::head ($) vs none". Get around this problem by just not importing LWP::Simple's head function, like so: `use LWP::Simple qw(!head); use CGI qw(:standard); # then only CGI.pm defines a head()` [download] As for "The first part of the script is" part: why are you parsing the QUERY_STRING yourself, when you're using CGI.pm anyway — as the warning and your line `my $id = param('id')` indicates? CGI.pm does the parsing already, so you can just drop that code...	[reply] [d/l] [select]
