currentDescriptionReturns the element value currently pointed to by the internal array pointer. This can be useful with next() and prev() in order to traverse an array; however, this is dangerous. The reason is that current() returns the value of the current element; if this evaluates to FALSE, there is no way to tell whether you've actually hit the end of the array being traversed or the current element simply has a value of FALSE. This function does not move the internal array pointer. ExampleExample 43. Get the value of the current element of an array $my_array = array("a","b","c","d","e"); echo "Current: ", current($my_array), "\n"; for ($i = count($my_array); $i >= 0; $i--) { echo "Next: ", next($my_array), "\n"; } reset($my_array); echo "Current: ", current($my_array); Output: Current: a Next: b Next: c Next: d Next: e Current: e
