Instead of lots of commands to output HTML (as seen in C or 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 <?php and ?> that allow you to jump into and out of “PHP mode.”
What distinguishes 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 would receive the results of running that script, but would not know what the underlying code was. You can even configure 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 part about using PHP is that it is extremely simple for a newcomer, but offers many advanced features for a professional programmer. Don’t be afraid to read the long list of PHP’s features. You can jump in, in a short time, and start writing simple scripts in a few hours
