next () Definition and usage
The next () function moves the pointer to the current element to the position of the next element and returns the value of the element.
If the internal pointer already exceeds the last element of the array, the function returns FALSE.
Grammar
Next (array) parameter description
Array required. Specifies the array to use.
Description
Next () and current () behave similarly, with only a little difference, moving the inner pointer forward one bit before the return value. This means that it returns the value of the next array cell and moves the array pointer forward one bit. If the result of moving the pointer is outside the end of the array cell, next () returns FALSE.
Note: If the array contains empty cells, or if the value of the cell is 0, the function will also return FALSE if it encounters these cells. To properly traverse an array that may contain empty cells or a cell value of 0, see the each () function.
Example
