Я пробовал много трюков и googling, чтобы решить эту проблему, но не мог получить полезный материал.
В основном следует содержание элемента из ассоциативного массива (результат экзамена кандидатов, и я должен дать рейтинг кандидатам), который содержит несколько таких элементов.
Я хочу сортировать массив в порядке возрастания, в зависимости от ключа [total_obtained_marks] , то есть кандидата, имеющего больше меток, будет первым ранжироваться,
то если такие же значения обнаруживают, что я должен сортировать массив в порядке убывания на основе ключа [no_wrong_answers] i.e. less no. неправильных ответов.
Даже если ранг остается таким же, я должен сортировать массив в порядке возрастания ключа [test_user_time_used] , то есть кандидат с меньшим временем использования получит более высокий ранг.
Даже тогда ранги одинаковы, тогда я должен отсортировать массив на ключе [user_first_name] в порядке возрастания по алфавиту.
После выполнения всего этого я мог бы получить отсортированный массив, который будет иметь правильный рейтинг для кандидатов.
Еще одна вещь об этом несортированном массиве - фактические данные не могут быть отсортированы из базы данных, поэтому функции базы данных не могут использоваться.
Все, что должно быть сделано, будет на этом несортированном массиве. Пожалуйста, помогите мне решить эту проблему. Заранее спасибо. Имя ассоциативного массива - $ test_result .
