The next () function moves the pointer to the current element to the next element and returns the value of this element. If the internal pointer has exceeded the last element of the array, the function returns false.
Next () definition and usage
The next () function moves the pointer to the current element to the next element and returns the value of this element.
If the internal pointer has exceeded the last element of the array, the function returns false.
Syntax
Next (array) parameter description
Array is required. Specifies the array to be used.
Description
The behavior of next () and current () is similar. there is only one difference. before returning the value, move the internal pointer one byte forward. This means that it returns the value of the next array unit and moves the array pointer one bit forward. If the result of moving the pointer exceeds the end of the array unit, next () returns FALSE.
Note: If the array contains empty cells or the unit value is 0, FALSE is returned when the function encounters these cells. To correctly traverse arrays that may contain null cells or whose unit value is 0, see the each () function.
Example
The code is as follows:
$ People = array ("Peter", "Joe", "Glenn", "Cleveland ");
Echo current ($ people )."
";
Echo next ($ people );
?>
Output:
Peter
Joe
