perl - Can you use array elements when adding a new line to a CSV file? -


i writing perl script , using class::csv module. have array of numbers, 5 elements long 

$values[0] - $values[4]

i trying add new line csv file , populate new line values array. keep receiving error when try run script:

 failed create csv line line:  10252205   @ /usr/lib/perl5/site_perl/5.8.8/class/csv.pm line 257     class::csv::line::string('class::csv::line=hash(0x1f2d0f20)') called @ /usr/lib/perl5/site_perl/5.8.8/class/csv.pm line 435     class::csv::string('class::csv=hash(0x1f2c1c00)') called @ catchmailstats.pl line 116

here code csv construction:

# create csv file current data   $csv = class::csv->new(   fields  => [qw/month notspam probable quarantine spam total/],   );  # creates first row (headers) $csv->add_line({   month   => 'month',   notspam => 'notspam',   probable => 'probable',   quarantine => 'quarantine',   spam => 'spam',   total => 'total' });  # creates second row (values) $csv->add_line([$values[0], $values[1],$values[2],$values[3],$values[4], $total]);

i have tried using other notation style:

# creates second row (values) $csv->add_line({   month   => $values[0],   notspam => $values[1],   probable => $values[2],   quarantine => $values[3],   spam => $values[4],   total => $total });

neither style has worked. here have noticed, though. final variable, $total, sum of $values[1] through $values[4]. variable work fine.

so real question is: why won't references elements in array work, summation of elements same array, compile without problem? , how can add_line function accept array elements?

i think in values list, there's hash ref needs dereferenced.

use data::dumper in code :

use data::dumper; print dumper @values;

and post output, see.
