按ASC顺序对数组进行排序，具体取决于两个键值？(Sort array in ASC order depending on two key values?)

我有一个存储在一个变量中的数组。该阵列如下：

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。

I have one array that is stored in one variable. The array is following:

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 ) )

I have done with sorting of array in ascending with employee_name that is running very fine with this code:

$attendances = "above array"; uasort($attendances, function($a, $b) { return strcmp($a["employee_name"], $b["employee_name"]); }); // this code is sorting in ascending order with employee_name.

Now what i want is that every employee_name should be ascending order and each employee_name today_date should also be in ascending order. My expected output is like that:

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 ) )

Please help me how to resolve this problem. I will not go with SQL query for some reasons. Thanks in advance.

最满意答案

这可以根据您的输出要求正常工作。尝试这个：

array_multisort(array_column($attendances, 'employee_name'), SORT_ASC, array_column($attendances, 'today_date'), SORT_ASC, $attendances); echo "<pre>"; print_r($attendances);

输出： - https://eval.in/935967

This works fine based on your output requirement. Try this:

array_multisort(array_column($attendances, 'employee_name'), SORT_ASC, array_column($attendances, 'today_date'), SORT_ASC, $attendances); echo "<pre>"; print_r($attendances);

Output:-https://eval.in/935967
