What Is PHP?

PHP is a general-purpose programming language intrinsically designed for web development. It was Basically Developed by Rasmus Lerdorf in 1994 the PHP reference implementation is produced by PHP Group.Since 2014, work has gone on to make a formal PHP specification.

lots of options command to procreation HTML (as seen in Perl), PHP pages contain HTML with embedded code that does "something" (in this case, output "Hi, I'm a PHP script!"). The PHP code is enclosed in special start and end processing instructions    that access you to jump into and out of "PHP mode."

What difference PHP from something like client-side JavaScript is that the code is executed on the server, generating HTML which is then sent to the client. The client will receive the results of running that script, but would not know what the underlying code was. You can compute your web server to process all your HTML files with PHP, and then there's really no way that users can tell what you have up your sleeve.

The best things in using PHP are that's so simple for a newcomer, but offers many advanced features for a professional programmer. Don't be frightened reading the long list of PHP's features. You can jump in a short time, & start writing simple scripts in a few hours.
