继上一篇文章:PHP二维数组排序自定义函数,今天,我们再介绍一个php二维数组排序的例子。
php对二维数组的排序很简单,主要用到array_multisort函数。
例子:
<?php /** * php二维数组排序 * edit www.jb200.com */ $data = array(); $data[] = array('volume' => 67, 'edition' => 2); $data[] = array('volume' => 86, 'edition' => 1); $data[] = array('volume' => 85, 'edition' => 6); $data[] = array('volume' => 98, 'edition' => 2); $data[] = array('volume' => 86, 'edition' => 6); $data[] = array('volume' => 67, 'edition' => 7); // 取得列的列表 foreach ($data as $key => $row) { $volume[$key] = $row['volume']; $edition[$key] = $row['edition']; } array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data); print_r($data); ?>
输出结果:
Array
(
[0] => Array
(
[volume] => 98
[edition] => 2
)
[1] => Array
(
[volume] => 86
[edition] => 1
)
[2] => Array
(
[volume] => 86
[edition] => 6
)
[3] => Array
(
[volume] => 85
[edition] => 6
)
[4] => Array
(
[volume] => 67
[edition] => 2
)
[5] => Array
(
[volume] => 67
[edition] => 7
)
)
说明:
array_multisort函数的参数非常灵活,大家可以参照php手册中的说明,深入研究下。
