如何在PHP中编写MongoDB foreach查询代码

如何在PHP中编写MongoDB foreach查询代码

现在我必须用PHP编写相同的MONGODB查询，使用迭代器\u to \u数组，我不知道如何在PHP中执行此查询

现在我被绊倒了。 我已经用一些例子给出了我的数据

使用MONGO查询：

db.getCollection('DRUM').find({'CODE': 'XXYYZZYY'}).forEach(
function(doc)
{
    print(doc.COLLECTION.DAY);
});

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      },
      "MONTHLY" : {
         "2017-06-01" : {
            "id" : 564444
         },
         "2017-05-01" : {
            "id" : 565455
         }
      }
   },
   "success" : true
}

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      }
   },
   "success" : true
}

实际数据库记录：

db.getCollection('DRUM').find({'CODE': 'XXYYZZYY'}).forEach(
function(doc)
{
    print(doc.COLLECTION.DAY);
});

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      },
      "MONTHLY" : {
         "2017-06-01" : {
            "id" : 564444
         },
         "2017-05-01" : {
            "id" : 565455
         }
      }
   },
   "success" : true
}

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      }
   },
   "success" : true
}

预期输出：

db.getCollection('DRUM').find({'CODE': 'XXYYZZYY'}).forEach(
function(doc)
{
    print(doc.COLLECTION.DAY);
});

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      },
      "MONTHLY" : {
         "2017-06-01" : {
            "id" : 564444
         },
         "2017-05-01" : {
            "id" : 565455
         }
      }
   },
   "success" : true
}

{
   "CODE" : "XXYYZZYY",
   "COLLECTION" : {
      "DAY" : {
         "2017-06-05" : {
            "id" : 565455
         },
         "2017-06-15" : {
            "id" : 565445
         }
      }
   },
   "success" : true
}

不能直接从php执行相同的查询。您必须首先从mongo获取记录，然后迭代该结果

下面是我的代码，用于PHP7 mongodb驱动程序

//connection object
$connection = new \MongoDB\Driver\Manager("mongodb://127.0.0.1:27017");

$filter = ['CODE' => 'XXYYZZYY'];
$projection['projection'] = ["COLLECTION.DAY" => 1,"CODE" => 1];

$query = new \MongoDB\Driver\Query($filter,$projection);
$cursor = $connection->executeQuery('DB_NAME.DRUM', $query);
foreach($cursor as $key => $row) {
    print_r($row); //your expected output
}
