【功能】

以二维数组的某一列的值作为键，对元素进行归类，重新整理出一个数组 。

【参数】

$arrlist: 二维数组
$key: 键名

【用例】

<?php

$conf = include "./conf.php";
include "./xiunophp/xiunophp.php";

$arrlist = array(array("a"=>1, "b"=>2), array("a"=>3, "b"=>4));
$r = arrlist_chunk($arrlist, "b");
print_r($r);

/* 结果：

Array
(
    [2] => Array
        (

                (
                    [a] => 1
                    [b] => 2
                )

        )

    [4] => Array
        (
            [0] => Array
                (
                    [a] => 3
                    [b] => 4
