If you belong to a technical background, you must be acquainted with this programming language. Even if you are associated with a non-technical sector, no worries. Here is a quick brief about the language for you! PHP is an open-source programming language. It is enlisted amongst the topmost programming languages in the tech world.

Moreover, it’s a server-side script, which means, the execution takes place on the webserver instead of the browser, as is the case of HTML. The amalgamation of both these languages results in the development of ample dynamic websites. 

When we talk about WordPress sites, you must know that all these sites run on PHP and HTML. Yes! That’s how popular and important these languages are. With this brief, let us move forward to our next segment and understand the life-cycle of PHP.

 

The PHP version in general has a life cycle of approximately three years. After this time period exhausts, they do not get any support. According to the official website of PHP, each branch of PHP is completely supported for a time period of two years from its initial release. Support here includes all the bugs, security issues, or other technical issues that are fixed and updated from time to time.

After the time bracket of two years exhaust, an additional year is provided to you to solve only critical issues associated with PHP. Once, this additional period also exhausts, the support also exhausts. Therefore, the version loses the security support and is prone to ample security threats. So, it becomes mandatory for you to update the PHP version from time to time. For additional data, take a look at this table to achieve a better grip over the topic.

Moving on, here is an analysis to make you understand the importance of updating PHP.

 

Various factors are taken into account. As you know, there are several ways to build your WordPress website. If you have built it with HTML, then the PHP update shows no changes at all. On the other hand, if you have created the site with the help of PHP, it functions better and in a refined way. The performance, speed, and overall experience improve. Also, do not forget to update WordPress itself, for a seamless experience. 

Additionally, there are situations when the code is outdated and the new version of PHP does not support it. In such cases, the site shows errors and hinders the work. 

 

For a better understanding, take this example into account. Suppose, you have not updated the latest version of CMS. Or your WordPress website consists of custom code and there is no update available for them. In that case, it is necessary to update your code to make it compatible and work-worthy. Therefore, updating PHP on your website holds great importance. There are ample benefits associated with the same. Let us analyze them.

  • Do check the PHP compatibility: There are several PHP compatibility plug-ins available to test the compatibility of all the themes and plug-ins with the latest update. You can install one of these to ensure that your tools or features go hand-in-hand with your new version. Additionally, if you encounter any technical issues after installing this plug-in, you can seek the assistance of a developer at any time.
