Two values for same variables in %in hash

himanshu.padmanabhi has asked for the wisdom of the Perl Monks concerning the following question:

If I get two values of any variable in my form,then how do I access both or how do I know there are two values?

Dumper(idx=8&args=&myname=ABCD.txt&idx=+&myname=+)

like here,'idx' and 'myname' contains 2 values. I am using ReadParse method of webmin module.It contains %in hash though which I can access elements from previous form. so in this form,to get 'myname',I can use $in{'myname'}

I guess that the ReadParse is from CGI. If that is the case, multiple values under a key are concatenated together using the ASCII 0 character (NUL Byte): `perl -MCGI -le 'CGI::ReadParse(); print for split /\0/, $in{myname}' \ 'idx=8&args=&myname=ABCD.txt&idx=+&myname=foobar'` [download] Output: `ABCD.txt foobar` [download]	[reply] [d/l] [select]

Don't use ReadParse for new programs, use param	[reply]
