If you need to delete any element from Perl array, what will you do? I know a function at Perl called splice(). Using the function you can easily remove any element or elements from your Perl array. Here goes few example blocks using splice() function.
Above example will declare an array of 10 elements from 1 to 10, then it will print all on screen. After that it will remove a single field from the array, and print again. You'll find that one element is deleted.
For your help, here is the properties of the splice() function.
## my initial array
my @array = qw(1 2 3 4 5 6 7 8 9 10);
## checking the output of my array
print join(' ,', @array) . "\n";
## removing only the elemtns from 5th index(first index = 0)
splice(@array, 5, 1);
print join(' ,', @array) . "\n";Above example will declare an array of 10 elements from 1 to 10, then it will print all on screen. After that it will remove a single field from the array, and print again. You'll find that one element is deleted.
For your help, here is the properties of the splice() function.
splice ARRAY, OFFSET, LENGTH
# removes anything from the OFFSET index to the index OFFSET+LENGTH-1
splice ARRAY, OFFSET, LENGTH, LIST
# same as the previous, but it will replaces elements removed with those in LIST
splice ARRAY, OFFSET
# removes anything from the OFFSET index till end
