PHP stands for “Hypertext Preprocessor”, is a programming language embedded in HTML that does all sort of things like build custom web content, send and receive cookies, evaluate form data sent from a browser, etc. It is integrated with number of popular databases like Postgre SQL, Oracle, Sybase, SQL, and MySQL. PHP also supports major protocols like IMAP, POP3 and LDAP.
PHP can handle forms, save data to a file, return data to the user, gather data from files, etc.
Example: Let say a website that takes user to view the order status after logging in. By PHP coding, you would send a query to the database that would then output the specific user information based on what information is in the database
