PHP vs Node.js: Which is better? - Plesk Shares Thoughts

PHP vs Node.js: Which is better?

JavaScript has been around a long time and has always been at the forefront of making things happen. That is, on the front-end – handling everything browser-side. For back-end, doing the heavy server-side stuff, we used PHP. Even on some of the most popular websites worldwide. Meanwhile, Node.js has really overturned the old way of doing things. So now it’s PHP vs Node.js – who wins?

The story of Node.js and PHP

Many wonder why Javascript was trapped in just front-end. It led to Node.js and the framework which allows JavaScript to not just run client-side, but everywhere. In this ideal world, developers could use a single language, both when programming client-side and server-side. In fact, Node.js has really taken off for a variety of reasons. And if you develop, you have an enormous amount of choices of platforms including the ultra-popular Angular JS.

PHP has also seen a huge amount of development with speed being one of the greatest benefits. At version 7, PHP has come a long way with JIT compiling a particularly popular feature of the later versions of PHP. Basically, PHP can now deliver just as quickly as Node.js and there’s also HHVM with hash which supports really cutting-edge programming techniques.

As always in technology, it’s not easy to decide what will lead the future. Sometimes there is a place for both competing technologies, sometimes it’s Betamax vs. VHS: only one will survive. But right now, we take a look at the situations where PHP serves you better, and point out the use cases where Node.js is a better choice.

Pro of PHP: Code and content together

As much as projects have different requirements for efficiency of code, logic and planning, it stays true that splitting the logic layer from the content layer is a wise choice. But do you want to spend time doing so? A PHP advantage is that it makes it easy to quickly add logic in the middle of HTML content. You can just trigger some logic by picking out a few markers in the URL, and tweak your content accordingly. Job done. And with some websites, that’s all you need.

Pro of Node.js: Everlasting power of MVC

A complex site with lots of logic snippet dispersed across pages can be difficult to manage. With Node.js you need to act in a more structured way (Model-View-Controller model). But with a complex application, structure is better for everyone. Node.js prompts you to lay code out in a way that is easy for you to maintain. And easy for a new project team member to understand. Yet, planning always takes time, and this structured approach might not be ideal under all scenarios.

PHP vs Node.js: Having variety against being up-to-date

Experienced programmers will know that an established code base is both a blessing and a curse. On the one hand, PHP provides you with a wide selection of libraries and frameworks, so you don’t have to write thousands of lines from scratch: almost every imaginable necessity has its implementation in code. However, this huge code base is not necessarily fresh or relevant. In the world of fast-moving web apps, this can be a liability.

Node.js, in contrast, offers a code base which is aware of the latest developments in web architecture. Though you may find fewer completed code chunks those which you do find will be more relevant. Besides, with Node.js you’ll find coding from fresh easy and quick because of its design. It fits into current development models, including the push for clients to do the heavy-lifting.

PHP vs Node.js: Simplicity but also flexibility

Though we’re currently on PHP 7.0, the initial purpose of PHP was simply to serve as a connector between HTTP requests and a server database. Considering how capable a database can be, this simple layer of basic functions and a couple of variables is often all that you needed. In fact, for a lot of use cases, all you need is that thin layer of PHP, and that’s it.

JavaScript, however, gives you more flexibility and the opportunity to pull in libraries by means of jQuery. It’s so powerful that you can shift functions around as if they were objects. Besides, Node.js is a modern language and despite some frustrating aspects also offer some really useful features, including the much-loved closures. So still PHP vs Node.js, but let’s keep going.

PHP vs Node.js: Growing code or multiple languages?

PHP code is expanding, but Node.js opens the doors to many languages. Many PHP developers have yearned to be able to do more with PHP than simply pull content from a database and present it in a tidy way. In a way their wish has been granted: you can now use HHVM (open-source virtual machine) to do much more than you could before, including the use of annotations and lambda expressions. Even if you are restricted to using HHVM for your code this is not so much of a problem as HHVM is actually very fast.

But why restrict yourself to HHVM when Node.js gives you what is literally dozens of options. With Node.js you can cross-compile so many languages that it really opens a world of opportunities. Whether you prefer C#, Lisp or other languages that could even include BASIC or, if you must, Pascal – there’s no arguing, you have choices. The fact that so many languages can be cross-compiled to run in JavaScript is a huge advantage in many situations.

Client-side code using Node.js

Downside

It’s true that some websites don’t need to execute any code on the client side. They simply use PHP to generate HTML from a database and get done with it. This is especially important when pages are rendered by mobile phones with small brains. Because you don’t want a code-heavy client side that gets bogged down with a slow mobile processor. Besides, simple HTML is less likely to lead to glitches.

Upside

Yet there are advantages to keeping some of the workload on the client side. And Node.js is simply more efficient, especially in terms of server usage. You send less data over the internet because there is less HTML mark-up. And you don’t need to submit a huge chunk of HTML code every time a little bit of data changes. AJAX takes care of all of this. This way of coding is ultimately  useful if your website is very data-driven, and requires more interaction from the user.

Database Queries: Advantages for both PHP and Node.js

If you’re familiar with and love SQL, PHP could be the best option for you. PHP was built closely to MySQL and databases similar to it such as Percona or Drizzle. Besides, you can easily connect to other SQL database from Oracle or even MS. Simply by making some basic changes to the code you use. Because SQL and the SQL code is so universal, it makes it really easy to work with databases and PHP.

JSON is not a bad alternative, however, as this too has a wide spread of databases it is compatible with. If you’re thinking of non-SQL databases for your application JSON can turn out to be quite a good solution. Though you can match JSON with PHP too, the similarity between JSON and JavaScript makes it great in a JavaScript environment.

It’s all about speed – but which?

Often there is a trade-off between the speed of writing the code, and the speed of an application executing. This is definitely the case with PHP and Node.js, with PHP being incredibly quick to put together. With PHP you don’t need a compiler or any JAR files. And PHP is an excellent choice if you need a working project really quickly.

On the flipside, PHP code doesn’t execute that quickly. In contrast, Node.js is code that executes smoothly and quickly reducing the load requirement on your server. You also get access to callbacks, which wastes less time when you try to deal with multiple different threads. You’ll spend more time coding and compiling with Node.js. But your code will be more optimized in the end.

PHP and Node.js Ecosystems

Finally, one distinction between Node.js and PHP that is worth keeping in mind is this: Node.js has a single code base. While there was a split in Node.js a while back, the group behind it has, for the most part, stuck to its guns and provided developers with the consistency they need.

However, the ongoing activity around PHP has benefits. Competing spur frameworks and libraries of the different teams want to add more useful features and improve performance. Zend and HHVM are both excellent projects. But there is a risk that, in the long-run, you’ll end up developing code on a code base that is relegated to the ash heap.
