Dereferencing ?

[Joe McGuckin]

If I have the following, how do I get to the members?

$servers = [{'hostname'=>'secure',
'description'=>'www'},
{'hostname'=> 'www3',
'description'=>'www'},
{'hostname'=>'www6',
'description'=>'www'}.
{'hostname'=>'www10',
'description'=>'www'},
{'hostname'=> 'mail',
'description'=>'mail'}];


I used to have a simple list of servers and I would say something like:

foreach $i (@servers)

But now I want to associate more info with each server entry.

So, how can I get my list of servers to iterate over?

Thanks,

Joe

You have a reference to an array of hashes. Assuming that you correct
the typo, you can print them like this:

foreach my $server (@$servers) {
print "Host: $server->{hostname}, Desc: $server->{description}\n";
}
