Synopsis
mixed next(array array)Increments the internal pointer to the element after the current
element and returns the value of the element to which the internal
pointer is now set. If the internal pointer already points beyond the
last element in the array, the function returns false.
Be careful when iterating over an array using this function—if
an array contains an empty element or an element with a key value of
0, a value equivalent to false is returned, causing the loop to end.
If an array might contain empty elements or an element with a key of
0, use the each function instead of a loop with
next.
