二維數組按值排序

//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'),    );

//排序後$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'),    );

求大神解答排序演算法！

雖然樓下給出了答案，但是本人的另一位朋友又給出了一種更簡便直觀的方法，如下：

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

回複內容：

//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'),    );

//排序後$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'),    );

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

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 方法比較靈活。

array_multisort() 函數 樣本如下

$data[] = array('volume' => 67, 'edition' => 2);$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);
