Why was PHP created?
The answer is easy. Internet would not have been possible if back-end languages were not in existence. For example whenever a user searches for a particular service or a term on search engines like Google or Yahoo. They show the relevant websites regarding that service or whenever a user fills a form for job or admission. Website knows exactly what to do with that data or how to process it in order to return the appropriate result to the user. Consider this example. Whenever we enter our sign up details (Account id and password) on any social media platform, like Facebook or Twitter. Then that data is stored on their server. Now the back-end developers of those websites manage that data and all your information to ensure safety, privacy and fast retrieval as well.
