PHP next() Function: Advancing the Internal Array Pointer
The PHP next() function moves an array's internal pointer forward by one position, returning the value of the next element or FALSE when no more elements exist, and is demonstrated with sample code showing how to retrieve successive items from an array.
The next() function in PHP behaves similarly to current() but first advances the internal array pointer by one position before returning the value. It accepts a single argument, the array whose pointer is to be moved, and returns the value of the next element or FALSE if the end of the array is reached.
Parameter:
array – The array whose internal pointer will be affected.
Return value: The value of the next array element, or FALSE when there are no more elements.
Example:
In this example, next($transport) advances the pointer and returns the subsequent value each time it is called, while prev() moves it backward and end() jumps to the final element.
