复制代码 代码如下:
/*
用手册上的例子
*/
$input = array ("a", "b", "c", "d", "e");
$output = array_slice ($input, 2); // returns "c", "d", and "e",
$output = array_slice ($input, 2, -1); // returns "c", "d"
$output = array_slice ($input, -2, 1); // returns "d"
$output = array_slice ($input, 0, 3); // returns "a", "b", and "c"
?>
重点说下length 为负.它表示取数组一直到距离数组末端length这么远的距离
