Most dynamic websites are created not only with one of these programming languages but with the two of them.
What Is PHP Used For?
PHP was developed in 1994 by Rasmus Lerdorf; its name originally came from Personal Home Page, and it was a set of scripts used by Rasmus to track visits to his site. Nowadays, PHP stands for Hypertext Preprocessor, and it’s an open-source scripting language for back-end development.
PHP is used to manage dynamic content, databases, session tracking, and e-commerce sites. According to W3Tech’s data, PHP is currently used by 78.9% of all websites with a known server-side programming language. This means that 8 out of 10 websites you visit on the web are using PHP. And in terms of market share, 78.9% means 20 million websites and applications using PHP.
PHP developers can:
- Create dynamic content.
- Open, write, read, delete and close files on the server.
- Receive and send cookies.
- Collect data from forms.
- Modify database information.
- Perform data encryption.
Companies such as Facebook, Wikipedia, Slack, WordPress, and MailChimp are currently using PHP.
- Create interactive features and forms for websites.
- Develop mobile applications (nowadays. JS is no longer exclusive for websites).
- Create web browser-based games.
- Back-end web development.

1. Server-Side vs Client-Side scripting
PHP is a server-side scripting language – which means that it interprets scripts on the server-side rather than on the client-side. This type of scripting is used at the backend, where the source code is not hidden at the client-side (browser). Server-side scripting is also useful in customizing the web pages and implementing dynamic changes on the website.
PHP has all the server-side functions such as building custom web content, authenticating users, displaying results, and overall managing requests.
PHP includes multi-threaded that is synchronous by nature. This means that it blocks input/output to perform multiple tasks simultaneously with a systematic approach. In simpler words, despite being ‘multi-threaded’, developers can’t execute the second line of code until the first one is, making it slower than other languages.
If you’re looking to build a dynamic web page, PHP is the programming language you’re looking for. But if you’re looking for a scripting language with more functionalities, likely JS is the better option.
5. Database Integration
Now you might be asking: are databases useful because…? They are helpful in terms of searching, sorting, and filtering information to present to a user. For example, if you’re trying to build an e-commerce, analyzing the data can give you information about how the users interact with the products.
Here’s a table that sums up the main differences among both programming languages:
|Server-side scripting language||Client-side scripting language|
|Back-end||Back-end and Front-end|
|Multithreaded language||Single-threaded language|
|Builds high-level interactive web pages||Builds user-friendly creative web pages and other software products|
|Slow performance||Fast performance|
|Best for e-commerce and other CMS websites||Best for SPAs|
|Database integration||Doesn’t have database integration|
