1) map the array elements to a hash, delete the key of the element you want to remove and map them back to an array.

my @array = ("zero", "one", "two", "three", "four");
my %hash = map { $_ => "1" } @array;
delete $hash{"two"};
@array = keys %hash;
print "@array\n";

Note that you won't get the keys out of a hash in the order you put them in unless you use a tied hash.

2) If you know the array index, use array slices.

my @array = ("zero", "one", "two", "three", "four");
my $remove = 2; # let's remove 2!
@array = (@array[0 .. ($remove - 1)], @array[($remove + 1) .. $#array]
+);
print "\n@array\n";
print $array[0], "\n", $array[3];
