current

Return the current element in an array

mixed **current**  $array

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

arrayThe array.

The 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, returns false. current``current

<?php
$transport = array('foot', 'bike', 'car', 'plane');
echo $mode = current($transport), PHP_EOL; // $mode = 'foot';
echo $mode = next($transport), PHP_EOL;    // $mode = 'bike';
echo $mode = current($transport), PHP_EOL; // $mode = 'bike';
echo $mode = prev($transport), PHP_EOL;    // $mode = 'foot';
echo $mode = end($transport), PHP_EOL;     // $mode = 'plane';
echo $mode = current($transport), PHP_EOL; // $mode = 'plane';

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

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

Opmerking: > The results of calling on an empty array and on an array, whose internal pointer points beyond the end of the elements, are indistinguishable from a false element. To properly traverse an array which may contain false elements, see the foreach control structure. current``bool

To still use  and properly check if the value 
is really an element of the array, the  
of the  element should be checked to be strictly 
different from null.
