## arrlist\_chunk()
```
<pre class="calibre11">```
arrlist_chunk($arrlist, $key)
```
```
#### 【功能】
以二維數組的某一列的值作為鍵，對元素進行歸類，重新整理出一個數組 。
#### 【參數】
```
<pre class="calibre11">```
$arrlist: 二維數組
$key: 鍵名
```
```
#### 【用例】
```
<pre class="calibre11">```
<?php
$conf = include './conf.php';

$arrlist = array(array('a'=>1, 'b'=>2), array('a'=>3, 'b'=>4));
$r = arrlist_chunk($arrlist, 'b');
print_r($r);
/* 結果：
Array
(
[2] => Array
(
[0] => Array
(
[a] => 1
[b] => 2
)
)
[4] => Array
(
[0] => Array
(
[a] => 3
[b] => 4
)
)
)
