Array of Hashes	Can't Post

Hi,

I have some piece of code below,

@array = (1,2,3,{"perl"=>1,"unix"=>2});

now, I want to print the entire contents of array( including the values of the hash)

How is it possible?

Loop through the array elements checking its reftype and then use the proper construct to output that data type.

Check out the reftype function in the Scalar::Util module.
http://search.cpan.org/~gbarr/Scalar-List-Utils-1.21/lib/Scalar/Util.pm

Then work up some code and post back with that code when you run into a problem that you can't figure out.

Yes, use Data::Dumper. It's a standard module that comes with Perl. See `perldoc Data::Dumper` http://perldoc.perl.org/Data/Dumper.html

I love Perl; it's the only language where you can bless your thingy.

Perl documentation is available at perldoc.perl.org. The list of standard modules and pragmatics is available in perlmodlib.
