Output: The result can be an HTML page that’s rendered by the web browser.

In the three-step process referred to above, we can identify a few components. Now, let’s see how they relate with an average WordPress environment. PHP Scripts: WordPress is essentially a vast, arranged assortment of code written in multiple scripting languages, such as PHP, JavaScript and CSS, with the principal one being PHP. It’s what provides WordPress its dynamic nature.

PHP Engine: Think about it as the central component that executes the instructions laid down in the PHP script – doing this with the help of the server it’s working on. The PHP Engine is one of the most important components, and impacts the speed, dependability and performance of a website. It’s also the central topic of our discussion! Server: This is the remote computer, known as the ‘web host’ also, where your WordPress site is hosted. If there have been a hosting company without PHP installed, WordPress would not run on it.

Output HTML: Whenever a WordPress website is packed, the PHP engine is summoned. Scripts are carried out by the PHP engine using the server, and the final (or output) HTML is exported to the visitor’s web browser. And that’s what completes the procedure. WHAT’S PHP 7? Now that we’re clear on what a PHP script is, let’s discuss the PHP Engine. For the remainder of this article, we’ll use the terms ‘PHP engine’ and ‘PHP’ synonymously. PHP 7 is a PHP engine that premiered in December 2016, and carries a plethora of new features, performance improvements and security enhancements.

As with every good lesson, let’s focus on a bit of background. PHP was released in 1994 as a scripting language by Rasmus Lerdorf in order to create a tool that would make updating his personal homepage easy. Over the full years, PHP has had a couple of releases. Is it the anticipation which makes PHP 7 special? That’s where things started to get interesting. Two years down the relative series, PHP 7 came along – the most promising release of PHP to time. The wait didn’t go to waste materials.

PHP 7 was included with a truckload of performance and security improvements. Let’s dig into each performance improvement, backed by solid benchmarks. In the chart above, we can see 2 almost. 18 times the number of requests per second at not even half the latency. Latency is the quantity of time elapsed between the first request and the first response between the server and client.

The lower the latency, the better the ongoing service. Let’s check out how PHP 7 handles it. We’ve used three data factors based on the number of concurrent users for every PHP engine. 1. The orange pubs stand for the latency when ten people are employing your site concurrently. 2. The blue bars are for dual (i.e. 20 concurrent users).

3. The red pubs are for 40 simultaneous users. In all cases, PHP 7 knocks its predecessors from the park. Which means that if you were to upgrade to PHP 7 with all the necessary compatibility bank checks in place (more with this later), you should see a two-fold upsurge in performance.

WordPress 4.0 itself has been fine-tuned to leverage PHP 7’s latest features. In the graph above, we see that a two-fold performance improvement in a major WordPress upgrade there’s. This benchmark is irrespective of the version of PHP. Rather, it is an indication that the WordPress community is consistently optimizing code for the upcoming versions of PHP.
