Perl/Basics/Variables and Data Types/Helper Functions/Unshift
From NetSec
The unshift() function is like the inverse of the push() function and treats the array like a stack. In stead of pushing to the top of the stack, this function operates against the bottom of the stack.
my @array; $array[0] = 1; unshift(@array,0); # $array[0] now contains "0" and $array[1] now contains [1]. |
