- Synopsis:
- $delitem(<array> <item#>)
-
- 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
