Syntax: Mixed next (array array);

Description:

Returns the next element that the internal indicator of an array refers to, and returns False if there is no next element.

This function is similar to current (). But the difference is that this function moves the internal metric of the array before returning the element, meaning that the function returns the elements of the next array and the internal metric of the moving array, which returns false if the array's internal indicators are outside the elements of the array.

Warning: If an array contains empty elements, this function returns FALSE, and you can use each () function to process an array containing empty elements.

Reference: Current () End () prev () Reset ()
