delitem
Synopsis:
$delitem(
Technical:
This function is used to delete an entry from an array created with $setitem(
). If the item deleted is the only one present in the array, the array is
deleted too. If the item is not the last item in the array, all items beyond
it (with higher item numbers) are shifted down by one to fill in the gap.
Practical:
This function is used to delete items from an array. The uses for this are pretty
obvious. If you add items to an array, it follows that you might want to remove
them, too.
Returns:
-2 if the item does not exist in the array
-1 if the array does not exist
0 on success
Examples:
$delitem(array 2) deletes item 2 from array "array"
$delitem(fake_array 4) error, "fake_array" does not exist
$delitem(array -2) error, item -2 does not exist
