That’s the front-of-the-house, although. The waitstaff that every one guests see. Again-of-the-house runs a bit in another way; there are completely different cooks within the kitchen, they usually affect a bit of little bit of every part.
In terms of WordPress, the programming language PHP is what’s actually operating the present. You’ll discover PHP in every part out of your WordPress dashboard (again finish) to your web site web page templates (entrance finish). PHP can be in your plugins, your theme… mainly, your web site doesn’t exist with out it.
PHP is an open supply, free-to-use programming language, and since it’s so accessible, it’s one of many most-used programming languages in net improvement (Fb makes use of it, too).
Right here’s how the back-of-the-house impacts the front-of-the-house: PHP primarily takes info out of your database, packages it as CSS and HTML, after which creates your beautiful web site for guests to see.
The ethical: PHP is fairly rattling essential, particularly when you have a WordPress web site – at the least a WordPress web site that you simply need to carry out nicely.
PHP Requires Updates
Since PHP is central to WordPress, it’s all the time being tweaked and improved – there have been quite a bit of variations over time. As of the writing of this text, you must have at the least model 7.zero, although 7.three is the newest model. By upgrading, you’ll entry the most recent PHP model, which additionally means the quickest, most secure and simply plain higher model.
The largest modifications with PHP 7 are that it’s roughly twice as quick because the final model, PHP 5.6; code is simpler to learn and assist; script issues are resolved easily; and its purposes are tougher to hack.
P.S. In the event you proceed utilizing an older PHP model, you received’t be capable to entry lively assist any longer, and safety assist will ultimately run out, too. Translation: your web site received’t be protected and also you received’t be capable to get any assist with it ought to one thing go fallacious.
Let’s Test Your WordPress PHP Model
Earlier than you replace your PHP, discover out should you even must by figuring out the PHP model you have got proper now. There are two easy methods to do that:
Test With Your Host
That is what I did. Truly, what I technically did was e-mail DreamHost to say, “Umm, my web site appears to hate me these days.” They usually have been like, “Yeah, it’s mad at you for having out-of-date PHP.”
In the event you can’t come up with your host’s customer support, you’ll be able to most likely verify the model your self. Search for one thing like “PHP Settings” or “PHP Model,” or “Handle Domains.”
In DreamHost, you’ll find out the model on the Handle Domains web page.
Use a PHP Model Plugin
You need to use a plugin like Show PHP Model, which is presumably the simplest factor I’ve ever executed in terms of WordPress.
You simply set up, activate after which see the model you’re utilizing within the At a Look part on the Dashboard:
Is it Time to Improve Your PHP Model?

Let’s go over find out how to stop that from taking place.
You are able to do this in your reside web site, however a fair safer resolution is to make a neighborhood copy of your web site and undergo the method on that first as a take a look at run.
Improve Every thing (however Backup First)

Upgrading every part that’s out-of-date is an effective first step, but it surely’s not foolproof. Fortunately, they make a plugin for that. (There’s additionally the PHP Compatibility Checker from WP Engine, but it surely’s untested with latest WordPress variations.)
Set up, activate, click on the SG Optimizer hyperlink within the left-hand sidebar of the Dashboard, then click on on Atmosphere Optimization. Partway down the web page, you’ll see the really useful PHP improve and a hyperlink to “Test Compatibility.”
It took beneath 10 minutes (for my easy web site, at the least), after which I get this discover, so it seems like I’m good to go:

DreamHost suggests PHP 7.2, in order that’s the one I select. Then I save the modifications and get a discover that the modifications ought to happen in about 10 minutes. I am going again to WordPress, clear the cache and the PHP is up to date – two minutes, tops.

Even should you’ve executed your due diligence, web sites are recognized to be imperfect. As soon as your PHP is up to date, head over to your web site to verify all of it out. Click on every web page, take a look at the options and plugins, and so on.
