PHP 數(shù)組current和next用法

1.current

$transport = 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';

?>

2.next

$transport = array('foot', 'bike', 'car', 'plane');

$mode =

current($transport); //$mode = 'foot';

$mode = next($transport);?? // $mode

='bike';

$mode = next($transport);?? // $mode ='car';

$mode =

prev($transport);?? // $mode ='bike';

$mode = end($transport);??? // $mode

='plane';
