What is PHP?
PHP is a recursive acronym: PHP Hypertext Pre-Processor.
PHP is a programming language most commonly used on web servers to process
incoming requests. Now what does that mean?
When you type in a web page in the URL bar or click on a link your web
browser sends a "request" to a computer that serves information out, a
server, and that server processes the request based on request, which is
designed to be able to open many different files and even designed to handle
dynamic information.
PHP can take that dynamic information and:
- Gather specific information
- Add information to a database
- Send informative emails to you or your salespeople
- Securely identify web users
- Provide secure access to centralized information
- And much more
PHP processes a request, gathers the necessary html together and sends it
back as a response to the Web Browser. This means that the PHP code that
is used to create a web page never makes it to the browser, making it able
to do more secure functions than you can do in Javascript, which is
completely transparent to the user.
