Question

我在这里有一个用户数组，该数组有2个以上的用户，每个用户数组都有一个registration_date，licence_expiry_date，性别，电子邮件，年龄和姓名。

数组看起来像这样。

$Users = Array(
                    (0) => Array
                        (
                            (id) => '100',
                            (name) => 'Name & Surname',
                            (email) => 'email@email.com',
                            (age) => '25',
                            (gender) => 'male',
                            (registration_date) => '2019-01-03',
                            (licence_expiry_date) => '2019-09-03',
                        ),

                    (1) => Array
                        (
                            (id) => '101',
                            (name) => 'Name & Surname 1',
                            (email) => 'email1@email.com',
                            (age) => '22',
                            (gender) => 'male',
                            (registration_date) => '2019-03-03',
                            (licence_expiry_date) => '2019-02-03',
                        ),

                    (2) => Array
                        (
                            (id) => '102',
                            (name) => 'Name & Surname 1',
                            (email) => 'email1@email.com',
                            (age) => '25',
                            (gender) => 'male',
                            (registration_date) => '2019-01-03',
                            (licence_expiry_date) => '2019-09-03',
                        ),

                    (3) => Array
                        (
                            (id) => '103',
                            (name) => 'Name & Surname 3',
                            (email) => 'email3@email.com',
                            (age) => '25',
                            (gender) => 'male',
                            (registration_date) => '2019-08-03',
                            (licence_expiry_date) => '2019-10-03',
                        ),

                    (4) => Array
                        (
                            (id) => '103',
                            (name) => 'Name & Surname 4',
                            (email) => 'email4@email.com',
                            (age) => '18',
                            (gender) => 'female',
                            (registration_date) => '2018-01-03',
                            (licence_expiry_date) => '2019-12-03',
                        ),
                );

我要实现的是将其中的数据过滤到另一个具有一定条件的数组。例如，我希望仅针对年龄为25岁且registration_date在2019-01-01之后，而licence_expiry_date在2019-10-01之后的用户进行过滤。

预期结果如下所示

$UsersFiltered = Array(
                    (0) => Array
                        (
                            (id) => '100',
                            (name) => 'Name & Surname',
                            (email) => 'email@email.com',
                            (age) => '25',
                            (gender) => 'male',
                            (registration_date) => '2019-01-03',
                            (licence_expiry_date) => '2019-09-03',
                        ),


                    (2) => Array
                        (
                            (id) => '102',
                            (name) => 'Name & Surname 1',
                            (email) => 'email1@email.com',
                            (age) => '25',
                            (gender) => 'male',
                            (registration_date) => '2019-01-03',
                            (licence_expiry_date) => '2019-09-03',
                        ),


                );

Answer 1

您可以使用array_filter：

$UsersFiltered = array_filter($Users, function ($v) {
    return $v['age'] == 25 &&
           $v['registration_date'] > '2019-01-01' && 
           $v['licence_expiry_date'] < '2019-10-01';
});

请注意，由于您的日期为YYYY-MM-DD格式，因此可以按字母顺序进行比较，而无需转换为DateTime对象，时间戳或类似内容。

Answer 2

您可以使用array_filter，

$arr = array_filter($arr, function($val){
    return ($val['age'] == 25 && strtotime($val['registration_date']) > strtotime('2019-01-01') && strtotime($val['licence_expiry_date']) < strtotime('2019-10-01'));
});

Demo。

我使用>和<作为严格的比较，因为您没有提到大于或小于等于。

我使用strtotime进行日期比较。

Answer 3

您可以像这样使用array_filter：

$licence_expiry_date = new DateTime('2019-10-01 00:00:00');
$registration_date   = new DateTime('2019-01-01 00:00:00');

$UsersFiltered = array_filter($Users, function($element) use ($licence_expiry_date, $registration_date) {
    return $element['age'] == 25
        && DateTime::createFromFormat('Y-m-d', $element['registration_date']) > $registration_date
        && DateTime::createFromFormat('Y-m-d', $element['licence_expiry_date']) < $licence_expiry_date;
});

如何根据日期和ID筛选出PHP数组中的数据？
