WordPress plugin and theme developers often use transients API to store timely information in your WordPress database.
WordPress插件和主题开发人员经常使用瞬态API将及时的信息存储在WordPress数据库中 。
This allows them to reuse this information and make their plugins function faster. While this is an incredible performance technique, sometimes it may affect your website during testing or development.
这使他们可以重用此信息，并使他们的插件运行更快。 尽管这是一种令人难以置信的性能技术，但有时它可能会在测试或开发过程中影响您的网站。
For example, you may realize that certain elements like popular posts or Twitter widgets are not changing despite emptying WordPress cache.
例如，您可能会意识到，尽管清空WordPress缓存，但流行帖子或Twitter小部件之类的某些元素并未更改。
That’s usually because the transient for that particular feature is not working as expected. To fix the issue, your options are to wait until transients expire or manually fix it.
通常是因为该特定功能的瞬态无法按预期工作。 要解决此问题，您的选择是等待瞬态终止或手动解决此问题。
In this article, we will show you how to easily manage and delete transients in WordPress.
在本文中，我们将向您展示如何轻松地管理和删除WordPress中的瞬态。
什么是瞬态？ (What is Transients?)
The Transients API in WordPress allows developers to store information in your WordPress database with an expiration time. This helps improve WordPress performance and speed up your website while reducing overall server load.
WordPress中的Transients API允许开发人员在有效期内将信息存储在WordPress数据库中。 这有助于提高WordPress性能并加快网站速度，同时减少总体服务器负载。
For example, many WordPress social media plugins use transients to retrieve and store share counts for posts.
例如，许多WordPress社交媒体插件使用瞬态来检索和存储帖子的共享计数。
If they didn’t use transients, then your server will need to connect with all social networks on each page load which will slow down your site significantly.
如果他们不使用瞬态，则您的服务器将需要在每次页面加载时与所有社交网络连接，这将大大降低您的网站速度。
That’s why transients are awesome.
这就是瞬态很棒的原因。
Now you may be wondering, why would you ever want to manage or delete transients?
现在您可能想知道，为什么要管理或删除瞬变？
Well, things can go wrong sometimes. Let’s say a connection between Facebook and your site didn’t go so well, and now it’s showing a count of 0. You can wait 30 minutes or sometimes longer for a transient to expire, or you can clear out the transient cache and get the most accurate count.
好吧，有时候事情可能会出错。 假设Facebook与您的网站之间的连接状态不佳，现在显示为0。您可以等待30分钟甚至更长的时间以使瞬态失效，或者您可以清除瞬态缓存并获取最准确的计数。
It also helps when testing a plugin to make sure that it’s really working like it is supposed to.
在测试插件以确保其确实按预期工作时，它也有帮助。
Last but not least, you may want to delete expired transients to clear out your database. This comes in handy when you are moving a staging site to live WordPress hosting server.
最后但并非最不重要的一点是，您可能希望删除过期的瞬态以清除数据库。 当您将登台站点移至实时WordPress托管服务器时，这非常方便。
Are WordPress transients like cookies?
WordPress瞬变像cookie吗？
WordPress transients are like cookies but only in the sense that they both allow developers to store temporary information. However, transients are much more powerful.
WordPress瞬态就像cookie一样，但仅从某种意义上说，它们都允许开发人员存储临时信息。 但是，瞬变要强大得多。
For example, cookies are stored in the user’s browser and have several limitations. They are also less secure and not as programable.
例如，Cookie存储在用户的浏览器中，并具有一些限制。 它们的安全性也较差，也不容易编程。
Transients, on the other hand, are stored in the WordPress database, can store different types of data, more secure, and easily programmable with the transients API.
另一方面，瞬态存储在WordPress数据库中，可以存储不同类型的数据，更安全，并且可以使用瞬态API轻松编程。
That being said, let’s take a look at how to easily manage transients in WordPress and delete them when needed.
话虽如此，让我们看一下如何轻松管理WordPress中的瞬态并在需要时将其删除。
