In the previous introductory PHP tutorial we talked about what PHP looks like and in what kind of environment it runs. To sum up, we said that we write PHP code between tags that look like this: “<?php … ?>” and we end every command line must and in semicolon (;). We use “echo” or “print” in order for PHP to show things to us. We also said that we need to have Apache server, PHP and MySQL installed in our computer or server so that PHP can run and we concluded that using a ready-made package like XAMPP, WAMP, or MAMP to achieve that would be optimal.
