Hello.
I would like to replace my scalar value(string) with a key's value(number), which is included in hash.
So if i have a month called January it should be changed to "01";
$month="January";
%months=('January' =>01,
'February' =>02,
'March' =>03,
'April' =>04,
'May' =>05,
'June' =>06,
'July' =>07,
'August' =>08,
'September'=>09,
'October' =>10,
'November' =>11,
'December' =>12
);
# if($month ?in? %months)
# { $month=%months{$month}; }
print "$month\n"; #output-> "01"
Thanx.
