Really? Try this: array size, or determine array size in perl.

But, what do you really mean by array size? The number of elements?

my @array = (1 ..4);
my $size = @array;
print "The size of array \@array is $size\n";

The memory size?

use Devel::Size 'size';
my @array = (1 ..4);
my $size = size(\@array);
print "The size of array \@array is $size\n";

Should you used an array reference, then you could do the same.

my @array = (1 ..4);
my $ar_ref = \@array;
my $size = @$ar_ref;
print "The size of array \@array is $size\n";

use Devel::Size 'size';
my $memory = size($ar_ref);
print "The size of array \@array is $memory\n";
