In my Drupal 7 Website, I have called an Ajax function by the click of a &nbsp;button to do some Database modifications by different queries. Everything goes well but in the end I need to remove the cache also via code. My file is in /templates folder. I have tried various search functions of drupal to clear cache but nothing works. <br />
<br />
Can any drupal 7 expert guide that how to clear the cache.<br />
<br />
Note: &nbsp;I am working on my custom functionality to Revert the Page contents to the last state. Everything goes well but when &nbsp;I clear the cache then user will be able to see fresh content otherwise not. So I need to clear cache via my ajax code.<br />
<br />
Looking forward for reply.<br />
<br />
Thanks

Clear Cache of Drupal 7 with Custom Code

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

Drupal is an open-source content-management framework written in PHP used as a back-end framework for websites and is also used for knowledge management and business collaboration. The standard release of Drupal contains basic features common to content management systems, including user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. Drupal runs on any computing platform that supports both a Web server capable of running PHP and a database to store content and configuration.

Drupal

Asynchronous JavaScript and XML (AJAX) is a group of interrelated Web development techniques used on the client-side to create asynchronous Web applications. With AJAX, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. HTML and CSS can be used in combination to mark up and style information. The Document Object Model (DOM) is accessed with JavaScript to dynamically display and allow interaction with the information presented.
