php - 二维数组按值排序

Question

//排序前
$arr = array(
    0 => array('id' => 'C160001-12'),
    1 => array('id' => 'C160001-10'),
    2 => array('id' => 'C160001-11'),
    3 => array('id' => 'C160001-4'),
    4 => array('id' => 'C160001-6'),
    5 => array('id' => 'C160001-3'),
    6 => array('id' => 'C160001-2'),
    7 => array('id' => 'C160001-5'),
    8 => array('id' => 'C160001-0'),
    9 => array('id' => 'C160001-8'),
    10 => array('id' => 'C160001-1'),
    11 => array('id' => 'C160001-9'),
    12 => array('id' => 'C160001-7'),
    );

//排序后
$arr = array(
    0 => array('id' => 'C160001-0'),
    1 => array('id' => 'C160001-1'),
    2 => array('id' => 'C160001-2'),
    3 => array('id' => 'C160001-3'),
    4 => array('id' => 'C160001-4'),
    5 => array('id' => 'C160001-5'),
    6 => array('id' => 'C160001-6'),
    7 => array('id' => 'C160001-7'),
    8 => array('id' => 'C160001-8'),
    9 => array('id' => 'C160001-9'),
    10 => array('id' => 'C160001-10'),
    11 => array('id' => 'C160001-11'),
    12 => array('id' => 'C160001-12'),
    );

求大神解答排序算法！

虽然楼下给出了答案，但是本人的另一位朋友又给出了一种更简便直观的方法，如下：

usort($statementsample,function($a,$b){
    return (int)substr($a['id'],8)>(int)substr($b['id'],8);
            });

Answer 1

function my_sort($a,$b)
{
    $a = explode('-',$a['id'])[1];
    $b = explode('-',$b['id'])[1];
    if ($a==$b) return 0;
    return ($a<$b)?-1:1;
}
usort($arr,'my_sort');

使用usort 方法比较灵活。

Answer 2

array_multisort() 函数 示例如下

$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);

$type = array();
foreach ($data as $key => $value) {
    $type[] = $value['edition'];
}
array_multisort($type, SORT_ASC, $data);
var_dump($data);
