PHP Twitter API搜索/tweets仅从上一小时获取tweets [英] PHP Twitter API search/tweets GET tweets from last hour ONLY
问题描述
我一直在Internet上四处逛逛，还没有找到解决方案.我只想获取过去一个小时的带有特定标签的推文.
Hi I have been looking around on the internet and haven't been able to find a solution yet. I want to only get the tweets from the past hour which have a certain hashtag.
我正在使用该标签添加推文，但我不知道如何仅获取过去一个小时的推文.
I am pulling the tweets in with that hashtag but I dont know how to only get the ones from the past hour.
以下是一些示例数据:
您可以看到那里有一个created_at日期，但是我不知道如何使用它来获取过去一个小时的日期.我认为这将是我能够做到的唯一方法.
As you can see there is a created_at date there but I dont know how to use this to get the ones from the past hour. I think this would be the only way that I would be able to do it.
我想到的最好的方法是将该日期转换为UNIX时间戳，然后检查它是否是最后一个小时的推文.但是有很多数据要经过，这似乎不是一个很好的解决方案，但我没想到.
The best way I can think of doing it is converting that date into a UNIX timestamp and then checking if it was tweets in the last hour. But there is a lot of data to go through and this doesnt seem like a very good solution but its all I cant think of.
如果这是唯一的解决方案，请问有人给我一个例子，说明如何将该日期转换为PHP中的UNIX时间戳.如果您有其他解决方案，我希望看到一个详细的示例:)谢谢
If that is the only solution there is, would some given me an example on how to convert that date to a UNIX timestamp in PHP. If you have a different solution I would love to see a detailed example :) Thanks

推荐答案
我也找不到替代解决方案，因此我对其进行了编码. WINDOW常数将时间间隔定义为1小时.希望对您有帮助！
I couldn't find an alternative solution neither so I coded it. The WINDOW constant defines the time interval to 1 hour. Hope it helps!
