Array
(
[0] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-11
)
[1] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-09
)
[2] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-10
)
[3] => Array
(
[employee_name] => GURVINDER
[today_date] => 2018-01-11
)
[4] => Array
(
[employee_name] => GURVINDER
[today_date] => 2018-01-10
)
)
我已经完成了使用employee_name进行升序排序,使用此代码运行得非常好:
$attendances = "above array";
uasort($attendances, function($a, $b) {
return strcmp($a["employee_name"], $b["employee_name"]);
}); // this code is sorting in ascending order with employee_name.
现在我想要的是每个employee_name应该是升序,每个employee_name today_date也应该按升序排列.我的预期输出是这样的:
Array
(
[0] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-09
)
[1] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-10
)
[2] => Array
(
[employee_name] => Amit
[today_date] => 2018-01-11
)
[3] => Array
(
[employee_name] => GURVINDER
[today_date] => 2018-01-10
)
[4] => Array
(
[employee_name] => GURVINDER
[today_date] => 2018-01-11
)
)
请帮我解决这个问题.出于某些原因,我不会使用SQL查询.提前致谢.
解决方法:
这可以根据您的输出要求正常工作.试试这个:
array_multisort(array_column($attendances, 'employee_name'), SORT_ASC,
array_column($attendances, 'today_date'), SORT_ASC,
$attendances);
echo "<pre>";
print_r($attendances);
