使用PHP中的推文查询MongoDB中的日期范围

Question

I have documents stored in MongoDB with each documents containing a "created_at" that looks like this:

"created_at" : "Wed Jan 24 15:25:20 +0000 2018"

I couldn't do a range query with a format like this. Should I update all of the documents and convert them into readable dates? Or is there a way in PHP where I should just convert the dates inside the PHP without updating/harming the documents inside MongoDB. The latter seems to be more sensible since I am constantly feeding my database with streams of tweets everyday.

Answer 1

You should reconsider the format you are using to store the created_at timestamp. I would recommend to convert this data to ISODate (js)/ MongoDB\\BSON\\UTCDateTime (php).

Using this format, you can do range queries in your MongoDB without heavy lifting on your php side.

Converting the data includes the following steps:

• One time data conversion (you update the already existing data in youor MongoDB)
• Changing the data inflow to use the new format for all newly added data
• Changing the view components to handle the new format.
