Answer: How do I make an array of hashes? contributed by chromatic my @array = (
{
'name' => 'Chuck',
'job' => 'roustabout',
},
{
'name' => 'CowboyNeal',
'job' => 'code monkey',
},
);
You can also use normal array operations (such as push) to modify an array:
push @array, { 'name' => 'vroom', 'job' => 'stacking blocks' };
print $array[0]->{name};
See perlman:perldsc for more information. | Answer: How do I make an array of hashes? contributed by fx If the hash has already been created, you can store references to the hash in arrays:
push(@array, \%some_hash);
and then when you pop them off:
$hash_ref = pop(@array);
you'll get a scalar back which can be dereferenced to get at the values of the hash:
$value = $hash_ref->{'key'}; |
