php取出数组的最后一个元素代码

$args=Array('www','111cn','net');

echo end($args);//net

$array = array(php,jsp,asp);
$count = count($array);
echo old:
;
for($i=0;$i<$count;$i++) echo $array[$i].
;
array_pop($array);
$count = count($array);
echo new:
;
for($i=0;$i<$count;$i++) echo $array[$i].
;
?>

输出结果:
old:
php
jsp
asp
new:
php
jsp

$user=array('apple','banana','orange');
$result=array_pop($user);
print_r($result);
print_r($user);

结果将是：
orange
array('apple','banana')

$array=array('step one','step two','step three','step four');
echo reset($array);
//输出：step one
