Simple 2 Step Guide to Check & Update WordPress PHP Version
Have you ever wondered how a website runs? Well, the main thing that is responsible for a website to run is coding. Besides, a website is also defined as a collection of webpage codes that describes the content, format, and layout of a page. Two more terms that are associated with it and help in displaying a website on the internet are web server and domain name. A web server is a computer that is connected through the internet and is mainly used to receive the webpage request sent by the browser. On the other hand, a domain name is an address that you usually type in the address bar of the web browser to get to a website.
PHP is the most important element of WordPress since it is essential in running the website on a web server. The things that you mostly notice at your website’s front end and back end are because of PHP. Apart from that, it is also present on the page templates, dashboard files, installed plugins or themes, etc. It is the main reason why website developers and designers say that WordPress won’t exist without PHP. So, in this article, we are going to talk about the basics of WordPress, the use of PHP to run the latest version, and how you can check and update it in the safest way.
WordPress is an open-source content management system that is written in PHP. A content management system or CMS is usually a tool that enables users to manage the different aspects of their website even if they know nothing about programming. It is usually paired with the MariaDB or MySQL database and often includes a template system that is referred to as themes and a plugin architecture. The reason why it became famous among the website owners is that it allowed them to operate and update a website or blog with ease. Since it was having a user-friendly interface, they do not even have the need to learn web designing.
Previously, WordPress was only used to create blogs. However, now, it can be also used for creating traditional websites of various types, such as e-commerce, social networks, portfolios, resumes, membership sites, businesses, forums, and more. It currently allows access to around 50,000 free plugins and 5000 free themes along with a variety of premium options. It is easy to install and will only require you to click a few buttons. Since it is a popular tool, it is also easier to find help if you run into any problems or difficulties. So, if you are planning to build a website, then go for it without any hesitation.

How to Safely Upgrade the WordPress Website’s PHP Version?
While it really sounds cool to upgrade to the latest version of PHP and run your website, there are still some risks associated with it. One of the deadliest risks that scare users the most is that the code used in core, scripts, themes, or plugins might not be compatible with the latest version. It will result in breaking your website and showing faulty behavior. So, if you want to avoid it, we strongly recommend you to follow the below steps. It will help you to update your live site safely and decrease the chances of running into any trouble.

Step 2: Check for compatibility problems with a plugin
There is no assurance that your website will run smoothly even if you have updated to the latest WordPress and extensions. In that case, you can carry out a compatibility test with the help of a plugin. You can use the free plugin (PHP Compatibility Checker) present in the WordPress directory that is released by the WP Engine. It will check all the codes, and report if there is an issue.
The first thing you need to do is install it on your website. A new menu called “PHP Compatibility” will appear under the Tools section once it is active. So, click on the desired PHP version you want to update and select the scan button for scanning all the extensions or only the active plugins.
After the scanning, you will get a list of errors and warnings for your website. Now, you can take the required action, i.e., either restoring the defective plugins or asking the developers to upgrade their works. Sometimes, the plugin might be flagged as non-compatible even though it is up to date. In that case, you can check the plugins that are known to be flagged even if they are not from the WP Engine.
Step 3: Upgrade the PHP version in Control Panel
Go to the Control panel and click on “Select PHP version”.
You can see the current PHP version of your website. Now, select the latest version of your drop-down menu.
Finally, click on the “Set as Current” button.
Step 4: Try to reach your host provider
If you are having trouble upgrading PHP through the control panel, then you can try to reach your hosting company. They can help you with that, and if not, they can also provide you instructions.
Step 5: Check your website now
The final step is to go back to the front end and check if every page looks good. Also, see if the other parts of your website are disabled and test out the plugins or theme features. Once it is done, you can rest assured that you have safely and successfully upgraded PHP for your site.
Whether you like it or not, PHP does play an important role in the working of a WordPress website. Not only does it help in running the website, but it also helps in increasing the site’s performance, and ensures faster loading. So, to avail all the above advantages, you need to run your website in the highest and latest PHP version. Also, get regular updates so that the site keeps running at its best form.
