php array element taking function

<?php
$people = array("Bill", "Steve", "Mark", "David");

echo current($people) . "<br>"; <span>// 当前元素是 Bill</span>
echo next($people) . "<br>"; <span>// Bill 的下一个元素是 Steve</span>
echo current($people) . "<br>"; <span>// 现在当前元素是 Steve</span>
echo prev($people) . "<br>"; <span>// Steve 的上一个元素是 Bill</span>
echo <code>end($people)</code> . "<br>"; <span>// 最后一个元素是 David</span>
echo prev($people) . "<br>"; <span>// David 之前的元素是 Mark</span>
echo current($people) . "<br>"; <span>// 目前的当前元素是 Mark</span>
echo reset($people) . "<br>"; <span>// 把内部指针移动到数组的首个元素，即 Bill</span>
echo next($people) . "<br>"; <span>// Bill 的下一个元素是 Steve</span>print_r (each($people)); <span>// 返回当前元素的键名和键值（目前是 Steve），并向前移动内部指针</span>
?>
