Just FYI, CGI.pm has a method to do that for you:
my $q = new CGI;
%params = $q->Vars;
>From the CGI.pm docs:
Many people want to fetch the entire parameter list as a
hash in which the keys are the names of the CGI
parameters, and the values are the parameters' values. The
Vars() method does this. Called in a scalar context, it
returns the parameter list as a tied hash reference.
Changing a key changes the value of the parameter in the
underlying CGI parameter list. Called in a list context,
it returns the parameter list as an ordinary hash. This
allows you to read the contents of the parameter list, but
not to change it.
When using this, the thing you must watch out for are
multivalued CGI parameters. Because a hash cannot
distinguish between scalar and list context, multivalued
parameters will be returned as a packed string, separated
by the "\0" (null) character. You must split this packed
string in order to get at the individual values. This is
the convention introduced long ago by Steve Brenner in his
cgi-lib.pl module for Perl version 4.
