get the length of a perl array

December 5th, 2006 by Lawrence David

perl sometimes is just too easy. so easy that it’s confusing.

for instance, to print the length of an array @my_array, you don’t need a length command or anything. instead, just code:

print @my_array;

(no way i’m ever going to remember a command that simple.)

   Yes, you got this wrong.

   “print @array” actually prints the contents of the array, not the length.

   Agreed, this will print the contents of the array, not the length.

   Hi,
   I think you can do something like this to get the length of an array:

   my $length;
   $length = @my_array;
   print $length;

   Really perlish.
