Php files use the extension ".Php", "Php3", or "Phtml" and Php is returning to the browser as plain HTML, In Php use any editor we use but notepad++, Dreamweaver  .

Now we can see how to create PHP code and how to run and show the output of the program. Here I print Hello World message in Php below you can see Php basic 

structure:

           <?PHP

                       ................................

                       ................................ 

                                           message want to display or statement  goes here

                      ..................................

        ?>

IN the above basic structure firstly we can see  <?PHP open tag which is required to start code of Php next line you can statement in simple word we can print any 

message here and between this logic and many other concept comes.

NOW we can write the program of  Hello World we can write code with HTML and without HTML but with HTML give more design and formatting.
