Perl Array Splice() Function - Quick Tutorial

Perl Array Splice() Function - Quick Tutorial The Perl splice function takes the following form: Perls splice() function is used to cut out and return a chunk or portion of an array. The portion that is cut out starts at the OFFSET element of the array and continues for LENGTH elements. If the LENGTH is not specified, it will cut to the end of the array. Example of the Perl Splice Function Think of the myNames array as a row of numbered boxes, going from left to right, numbered starting with a zero. The splice() function would cut a chunk out of the myNames array starting with the element in the #1 position (in this case, Michael) and ending 3 elements later at Matthew. The value of someNames then becomes (Michael, Joshua, Matthew), and myNames is shortened to (Jacob, Ethan, Andrew). Using the Optional REPLACE_WITH As an option, you can replace the portion removed with another array by passing it in the REPLACE_WITH argument. In the above example, the splice() function would cut a chunk out of the myNames array starting with the element in the #1 position (in this case, Michael and ending 3 elements later at Matthew. It then replaces those names with the contents of the moreNames array. The value of someNames then becomes (Michael, Joshua, Matthew), and myNames is changed to (Jacob, Daniel, William, Joseph, Ethan, Andrew).
