php的数组语法

<?php

$array = array('step one', 'step two', 'step three', 'step four');

// by default, the pointer is on the first element

echo current($array) . "<br />"n"; // "step one"

// skip two steps

echo next($array)."<BR />";

echo reset($array);

?>

reset -- 将数组的内部指针指向第一个单元

详见list() ,each(),[next()对应pre()][next(),each()会导致指针后移]
