What Is PHP Used For

PHP is an open-source server-side scripting language that is used for developing web applications. A scripting language is a bit different from a programming language as the programs are written in script and follow the line of code to automate the tasks. You might think that web pages are created using HTML, and the execution of the code is done on the user’s browser. But that’s not where all the things are done, behind the scenes is where the real work happens. The request is sent to the server using PHP scripting language. Once the request is executing on the server, the request is sent back to your browser. That’s how a web browser displays the webpage you requested. The use of PHP does not end there, and today we’re going to outline several different technology and computer science fields where it is regularly used.

PHP Real World Applications

For some people imagining PHP handling all the heavy-duty back-end tasks is completely impossible in today’s world. But it will come to you as a surprise to know that most of the startups that are now part of the Fortune 500 have one thing in common. That is the use of PHP in their back-end computing tasks. Facebook, Mailchimp, Slack, and other companies heavily rely on PHP to handle their back-end infrastructure.

Given below, we have compiled some of the best and massive real-world implementations of PHP which you might not be aware of. These are all real-world applications, and if you use one of these services or websites, you are actually receiving the data from the application using PHP server end scripting language.

1. Facebook

Yes, Facebook, one of the most used social media platforms to this date, used PHP for developing its website’s back-end infrastructure primarily. The main use of PHP in Facebook’s development was the ability to generate dynamic content. At the core, the main code is written in all PHP by Mark Zuckerberg and Moskowitz themselves. Once Facebook got popular and people started noticing its success, PHP got popular. As a result, the domino effect started, and then a large number of companies started using PHP in their upcoming and ongoing projects.

Facebook also gave something back to the PHP community. The company created HipHop for PHP, which is a transpiler or a compiler that can easily convert the source code written in PHP into the source code of another language.

2. Wikipedia

We all have been to Wikipedia numerous times, and without a doubt, it is one of the most visited public information websites on the internet. But one thing you don’t know about Wikipedia is that the website uses PHP as its main programming language along with MySQL, which handles the back-end database. The website was shifted to Hip-hop Virtual Machine created by Facebook in 2014, and since then, the page loading speed has doubled.

3. MailChimp

Mailchimp has completely changed the email marketing world. All credit for the success of the email marketing campaign belongs to the scalable PHP databases that operate on the website’s back-end and provide users with all the different information they require.

4. WordPress

WordPress is considered to be the largest content management system on the internet. If you are looking to create a website in no time for their blog, WordPress needs to be your first consideration. In WordPress, PHP is used to fetch out the main components from the database and output them in the form of static HTML.

As a result, WordPress can serve millions of users looking to create their first-ever website. Also, with PHP implementation at the back end, the website is able to provide drag and drop features for making templates and other UI components without requiring any coding knowledge from the user’s end.

5. Tumblr

If you are an artist, you sure have used Tumblr or might be using it consistently to share your ideas and get inspiration as well. You might not know this, but Tumblr was the birthplace of memes. Since its inception, users on Tumblr have created 325 million blogs. All these blogs and 555 million monthly active users need to access the data at a lightning-fast speed. As a result, in 2016, Tumbler shifted to PHP7, which led to an increase in the performance and the addition of new language features such as scalar type hints along with declarations of the return type.

Benefits Of Using PHP

PHP, also known as Hypertext Preprocessor, has several benefits, which helps in making it the best choice for a server-side scripting language. Given below, we have explained some of those benefits, so our readers can see how PHP can provide a boost to their websites.

1. Open Source

Being an open-source scripting language means that you don’t need to worry about the license when using PHP in your project. In addition to this, the source code of the scripting language is present online, and you can make changes to it according to your need without facing any legal charges. On the other hand, you will find tons of codes, frameworks and libraries already present on the internet which can solve your purpose, resulting in you not being required to write the whole code.

2. Easy Development

With PHP, a developer can make dynamic web content for their website and add in a number of tools along with other scripting languages like Magento, Joomla, WordPress, etc. Likewise, PHP is compatible with many operating systems, including Mac Os as well, so a developer doesn’t have to worry about PHP projects not working on Apple systems.

3. Manageable

There are a number of popular frameworks present that can upscale the level of development, allowing effortless customization. You can use CakePHP, Laravel, Phalcon, and others to manage your website’s customization.

4. Cost Friendly

There’s a reason why Mark Zukerberg used PHP when developing Facebook, and it’s the cost that you need to pay in order to maintain the website, hosting, and expansion. If we compare the cost of a website built using PHP vs. the other, we can clearly see that PHP is much more cheaper and affordable. Being open-source, a developer can do anything with the source and mend it according to the project requirement. Also, when using PHP, you are not required to implement it on your server-side.
