currentReturn the current element in an array


current ( array $array ) : mixed

Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.



The array.

Valorile întoarse

The current() function simply returns the value of the array element that's currently being pointed to by the internal pointer. It does not move the pointer in any way. If the internal pointer points beyond the end of the elements list or the array is empty, current() returns FALSE.


Această funcție poate întoarce valoarea Boolean FALSE, dar poate de asemenea întoarce o valoare non-Boolean care evaluează în FALSE. Vă rugăm să citiți secțiunea despre tipul Boolean pentru informații suplimentare. Utilizați operatorul === pentru a verifica valoarea întoarsă de această funcție.

Versiune Descriere
7.0.0 array is now always passed by value. Prior to this version, it was passed by reference if possible, and by value otherwise.


Example #1 Example use of current() and friends

= array('foot''bike''car''plane');
$mode current($transport); // $mode = 'foot';
$mode next($transport);    // $mode = 'bike';
$mode current($transport); // $mode = 'bike';
$mode prev($transport);    // $mode = 'foot';
$mode end($transport);     // $mode = 'plane';
$mode current($transport); // $mode = 'plane';

$arr = array();
var_dump(current($arr)); // bool(false)

$arr = array(array());
var_dump(current($arr)); // array(0) { }


Notă: The end of an array and the result of calling current() on an empty array are indistinguishable from a boolean FALSE element. To properly traverse an array which may contain FALSE elements, see the foreach() function. To still use current() and properly check if the value is really an element of the array, the key() of the current() element should be checked to be strictly different from NULL.
