The reason is unless you change how arrays are numbered, they
start at zero and go from there. You can also use -1 to get the last
element of an array as in $arr1[-1] would be 1 in the first example.
$arr1[0] = 6 from your first example.
If you have any questions and/or problems, please let me know.
Thanks.
