Question

I want to convert an array of hashes that I create like this:

while(...)
{
    ...
    push(@ranks, {id => $id, time => $time});
}

To JSON:

use JSON;
$j = new JSON;
print $j->encode_json({ranks => @ranks});

But it is outputting this:

{"ranks":{"time":"3","id":"tiago"},
 "HASH(0x905bf70)":{"time":"10","id":"bla"}}

As you can see it isnt able to write on of the hashes and there’s no array…

I would like to output a JSON string that looked like this:

 {"ranks":[{"time":"3","id":"tiago"},
           {"time":"40","id":"fhddhf"},
           {"time":"10","id":"bla"}]}

Answer 1

print $j->encode_json({ranks => @ranks});

should be:

print $j->encode_json({ranks => \@ranks});
