As others have alluded, you might want to look into the param() function, but the exact answer to your question is: 
#!/usr/bin/perl -w

use strict;  #Trust us

use CGI;
my $query = CGI::new;
my %data = $query->Vars();

This will work if the input came in from STDIN or via a webserver.

(Note: Masem above uses the same function in a scalar context to get a reference ($data). Used in a list context, Vars() will return a hash, which is what you asked for. Masem's solution is better if you intend to pass the data to subroutines, they work equally well if you treat them as global variables.)
