Basic Php Syntax and First Example

A PHP script can be placed anywhere in the document.
A PHP script starts with <?php and ends with ?>

Example:

               <?php
                  // PHP code goes here
               ?>


The default file extension for PHP files is ".php".

A PHP file normally contains HTML tags, and some PHP scripting code.

Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP function "echo" to output the text "Hello World!" on a web page:

Example:

                <!DOCTYPE html>
                <html>
                <body>

                 <h1>My first PHP page</h1>

                 <?php
                 echo "Hello World!";
                 ?>

                 </body>
                 </html>
