PHP Mongo 正则表达式

Question

我有如下mongo记录。

[1] => Array
    (
        [_id] => MongoId Object
            (
            )

        [id] => 195197
        [rec] => Array
            (
                [0] => Array
                    (
                        [id] => 195197
                        [data] => ways to skin a cat
                        [total] => 313
                    )

                 [1] => Array
                    (
                        [id] => 702724
                        [data] => 2010-07-25 15:09:40
                    )
            )

          [rec2] => Array
            (
                [0] => Array
                    (
                        [id] => 195197
                        [data] => ways to skin a cat
                        [total] => 313
                    )

                 [1] => Array
                    (
                        [id] => 702724
                        [data] => 2010-07-25 15:09:40
                    )
            )
    );

我想通过 Mongo 正则表达式从具有 rec 和 rec2 元素且“数据”元素采用日期格式的 mongo 数据库中搜索那些记录。有什么办法可以找到这样的记录吗？

Answer 1

在 shell 中，您应该能够执行如下操作:

db.foo.find( { 'rec.data' : /\d\d\d\d-\d\d-\d\d/ } )

在 PHP 中，您将使用 MongoRegex class .

看起来像这样:

$regex = new MongoRegex("/\d\d\d\d-\d\d-\d\d/");
$where = array("rec.data" => $regex);
$cursor = $db->foo->find( $where );
