PHP 7 was the most awaited and the most requested feature of recent times by Cloudways customers. After much trial and errors, PHP 7 was successfully integrated for all the users on Cloudways.
There was much hype in WordPress industry when PHP 7 was still in development. There are many reports on the web that reported a very impressive performance boost of WordPress when hosted on PHP 7. We went ahead and tested these claims to make sure our servers backed our statements.
You can also test that. As you know, Cloudways believes in keeping things simple as always inside the Cloud platform, this time is no different either. You can easily switch your servers from PHP 5.6 to PHP 7 by going to “Server Management” tab, then under “Packages” select “PHP 7“. It is a matter of just a few clicks and couple of minutes.
If you want to switch back to the older version, again, not an issue. You can always switch the version of PHP back to 5.6 whenever it is required. Although, upgrading your current servers with live websites to PHP 7 is not recommended until and unless you have gone through the following checklist:
- Make sure your WordPress version is compatible. The core of WordPress 4.4 and later are compatible with PHP 7.
- Make sure all your plugins and the current theme you are using on the live site are compatible with PHP 7.
- Any custom PHP code is compatible.
We will go over the process that we recommend for upgrading your current WordPress site to PHP 7.
But first, let’s have a look at the benchmarks. We tested WordPress on PHP 7. The result was 37,378 hits with 0 errors and 0 timeouts. Average response time was an impressive 4ms on vanilla WordPress 4.4 with caching.
If you compare these results with PHP 5.5, then you can see a very notable improvement in average response times.
WordPress on PHP 5.5 with caching resulted in 24,731 hits with 0 errors and 0 timeouts. The average response time was 208ms.
Recommended Method to Upgrade Your Live WordPress Site to PHP 7
As noted above, there are many things that one needs to check before upgrading their site to the latest version of PHP. Upgrading your PHP version is a major upgrade. Therefore, download a copy of website before doing anything. You do not want to lose anything in experimentation.
On Cloudways, you can follow the following checklist to move your WordPress websites to PHP 7.
- PHP 7 is best supported on Debian 8 servers. Since February 16, 2016, we have started using Debian 8 on all new servers. If you have servers launched before that, then we suggest you launch a new server and clone your website(s) to the new server.
- After your website is cloned on new server, navigate to Server Management tab -> Packages and select PHP 7.
- After your server upgrades to PHP 7, test all the features, plugins, and theme(s) of your WordPress website for compatibility.
- If everything seems to be in order, then point your domain to the new server to take your website live.
By the way, all of these tests were conducted under a controlled environment. This means they do reflect a real-time scenario, but results can vary from site to site. Why? Because, it’s WordPress. There are ever so many variable parts, like plugins and themes. A poorly coded theme or plugin can result in slow loading times. Therefore, always try to use high-quality WordPress plugins and themes. (Oh yeah! Seriously stay away from pirated themes and plugins.)
