PHP Use Cases
Many tech giants and companies from different backgrounds and domains use PHP as their main server-side language. We divided these companies in accordance with their domains. Some of these companies use PHP partially while others completely rely on this language.
Social Media Platforms
Social Media Platforms have their own websites where users access their social accounts to interact with other platform users. This requires better loading time and speed that PHP provides by fast querying to the database.
According to Similarweb, Facebook is visited over 22 Billion times every month.
Although PHP as a dynamic scripting language has a reputation for being difficult to scale, Facebook chose to scale its PHP monolith rather than breaking it up into distributed microservices architecture.
Scaling PHP with a just-in-time compiler Hip Hop Virtual Machine (HHVM) allowed Facebook to continue moving fast without going through a painful refactoring that would have slowed down the entire company.
PHP 7 (and upcoming PHP 8) got many features from Facebook's Hack language that Facebook created as a dialect of PHP.
Flickr is a photo-sharing platform with over ten million groups and billions of photos on the platform. They also use the LAMP model to power their site with PHP being their main server language while MySQL is used for databases and Memcached as a caching layer.
Flickr Architecture by High Scalability highlights from Flickr architecture:
- Think of your application as more than just a web application. You'll have REST APIs, SOAP APIs, RSS feeds, Atom feeds, etc.
- Go stateless. Statelessness makes for a simpler more robust system that can handle upgrades without flinching.
- Abstract. Create clear levels of abstraction between database work, business logic, page logic, page mark-up and the presentation layer. This supports quick turn around iterative development.
- Layer. Layering allows developers to create page level logic which designers can use to build the user experience. Designers can ask for page logic as needed. It's a negotiation between the two parties.
Tumblr is used by millions to share their ideas, images and blogs to engage with other people across the platform. Officially, the platform used PHP as its main server-side language. However, they also partially used Scala for performance reasons.
Tumblr team revealed in their blog post PHP 7 at Tumblr how new PHP features that can make the life of the developers at Tumblr a bit easier:
- Functions can have explicit return types that the language will enforce. This reduces the need for some boilerplate code and manually checking the return values from functions.

First, we found ourselves having to rewrite logic that was designed for being executed in a web context to be executed in an API context. This led to feature drift between the mobile and web platforms as the amount of shared code decreased.

Why are Companies using PHP?
The Flexibility of the Language
Despite being a dynamically typed language, PHP has a relatively simple syntax. There are no hard and fast rules when writing scripts and programmers can test their applications despite minor errors.
PHP Improves with Time
Unlike many other languages, PHP keeps evolving with time. The PHP Group listens to the queries and problems being faced by developers and they fix those issues in their latest version. They recently released PHP 8.0 which comes with multiple bug fixes.
Many developers also complain about the slow PHP speed, which was also fixed to some extent with the stable release of PHP 7. The language is constantly growing with new versions and enhancements every year.
New Features with PHP 7
Among all the previous releases, PHP 7 holds the utmost importance. This version was a major release and it is now becoming the most stable version of PHP. It came with many speed enhancements and features like the New Zend Engine to make code performance even better.
The Error handling features are also improved with the help of a new engine. The PHP team renewed the Zend Engine by optimizing its memory usage that now makes execution two times faster.
Developing a website using PHP is relatively inexpensive since the language is free and there are no license fees for the frameworks and libraries. PHP also integrates well with a variety of databases such as MySQL and Apache.
StackOverflow has the 3rd largest PHP community, allowing this community to assist you with any PHP questions or problems you may encounter.
Is PHP a good choice for Companies?
PHP offers a range of Frameworks with the most popular being Laravel and Symfony. These frameworks and PHP itself is heavily used in the backend of web systems to make pages load faster with better query processing. However, we have also seen that many companies use HHVM along with PHP to convert code into C++ for better and faster execution.
The language is reliable for those companies that are thinking of developing a web-based platform where users will interact with each other. Most popular CMS like WordPress is also built on top of PHP which further makes it easy to implement on your own site. The applications of PHP are a bit limited to web-based platforms and other languages like Java are far better for mobile apps.
