Today websites run not only on HTML but also the codes imply elements of CSS and JavaScript.

Apart from these, the PHP language is what makes things work. It plays a huge role in the server before loading the website.

However, when you want to update the version of the software you may experience difficulties. Constantly updating your website will keep it safe from hackers and fast enough for users.

But how do you avoid errors while updating PHP in WordPress? This article will answer all of these questions..

The relationship between PHP and WordPress

WordPress websites use PHP language. It plays the role of a coding language for servers. Years of collaboration has meant that every time WordPress was updated, the PHP language underwent some changes as well.

Many things on a WordPress site exist due to PHP. Such as themes and templates as well as simple files on your dashboard. PHP is also responsible for running all the plugins that help you organize your page.

Since PHP is vital for the functioning of your website, keeping it updated is also important, otherwise you risk facing errors and other problems.

Why is it important to update PHP on WordPress?


The PHP coding is the core of your entire website. It runs the server on which your website operates. It’s not enough to keep WordPress updated if you want to maintain the level of productivity of your page. You also need to work with the latest version of PHP..

You can think of PHP as the middleman between your client’s screen and your enormous database. It receives the right data and sends it to the visitor after transforming it into the product seen by the viewer. The entire performance of the website depends on how fast PHP performs these actions which is a good reason to keep it updated.

It is important to understand that the updating process is necessary and done correctly. It won’t break your coding, nor any other element of the site. On the other hand, it will bring you many advantages worth taking into account. Some of the following benefits should make you curious about how to update PHP in WordPress:

  • Increased efficiency: Making the program more efficient means increasing its speed. The last version of PHP (currently 7.3) can sustain 3 or 4 times more operations in the same span, in comparison to the older versions.
  • Safer website: Another advantage of the updates is the fact that they secure your site, thus making hacking it more difficult. When talking about PHP, hackers trying to harm you is a constant risk which is why you need the latest versions of the software. Developers constantly add the necessary anti-hack features required.
  • Better optimization: Google also determines the quality of websites by their speed. The faster your website, the higher your ranking on Google. Which means more clicks, more clients, more sales!
  • Possible problems after upgrading

    What makes most users reluctant to upgrade their PHP software is the compatibility problem. Once you get a new version of PHP, there’s a possibility of conflict with the old plugins or themes,which can seriously harm your site.

    On the other hand, your code will eventually be completely incompatible with the new version because you can’t keep the same version of PHP for years. So at this time you need to recalculate and modify your code.

    Things to do before starting the PHP update process

    Make a backup of your website


The security of your website is one of the most important reasons why you should do constant updates to your PHP software.. WordPress guarantees efficiency through its collaborations with PHP.

If you keep PHP updated, then you need to also update your website backup. Save the most recent version of your code in another place before starting any update process.

Thus, you’ll have reassurance that nothing should go wrong. If it does, you can return to the previous version of your website using the backup data.

If you haven’t backed up your code before, use a free plugin you can find online. We’ll also share with you later how a web host will help you revert the process.
