Why hash array and not array?

**Arez20469** · 08-10-2007, 02:27 AM

Code:

my(%form);
foreach my $p (param()) {
    $form{$p} = param($p);
}

print "Your name is $form{'name'}<br>\n";

How come you can't do @form instead of %form? don't get it..

What language is this ?

Asp, coldfusion, jsp ?
Don't looks like php, neither javascript...

It's Perl I assume?

I haven't used Perl in a long time, but I'm guessing that arrays are automatically indexed by integers as opposed to 'anything'. By using the hash array you can use strings as the array indices, too...

It's Perl, and I dunno what Twist meant!
