Today I want to look at something called PHP.

PHP is an open source scripting language and the bulk of the WordPress core is written in PHP. 

So it is vital that we make sure that the PHP is optimised. 

PHP has a number of versions, and one of the earlier ones is version 5.6 and that came out in 2014 and a scary thing is that 40% of websites are using this older version 5.6.

Today I’m going to show you how to check what version you’re using and how to upgrade it.

Let me show you something about the later versions.

You will see that there has been a massive improvement from 23014 until today.

PHP 5.5 this shows you the req`uests and the speed all the way upt o php 7.3

You will see that it is a lot faster.

PHP 7.3 is 10% faster than PHP 7.2 and PHP 7.3 is 31% faster than 7.0. But this is what is massively interesting, it’s nearly 3X the speed of PHP 5.5 or 5.6.

Remember that 40% of WordPress websites are usingt his outdated PHP script. It’s used in the WordPress core and used in many plugins and themes.

So, let’s see how we can update it from PHP 5.5 opr 5.6 all the way to PHP 7.3.

To do that jump into Cpanel and go to Multi PHP manager.

That will open something that looks like the screenshot in the video.

Here you can see the current PHP version used.

In this screen you change it to PHP 7.3 and select apply. Give it some time to update.

Not all sites will handle the newer version as it depends on your theme & plugins, so make sure that you test your website thoroughly after updating.

Check it all works as it should.

You jave now just upgraded the PHP version from a lower version to a higher version and depending on what version you’re coming from you can see some massive results for this.
