Change document from HTML to PHP

Navigation

People, how do I turn an HTML file into PHP? Just change the extension? Is it okay to do so? Apparently, my server read the page I changed from HTML to PHP, but I have doubts whether it's right or not, after all, I've just changed the extension from .html to .php .

Mikaela, imagine that you have a file named index.html with the content described below: 

<!DOCTYPE html>
<html>
    <head>
        <title>Aprendendo HTML e PHP</title>
    </head>

    <body>

        <p>Prazer, me chamo Godfrey the King.</p>

    </body>
</html>

You, as a curious person, decided to change the extension to .php .

When you open the page in your browser - remembering that you need to have a web server installed on your computer, which is easily installed using XAMPP, WAMP, EasyPHP, among others. - the following will appear: phrase:

"Prazer, me chamo Godfrey the King."

If you change the code a bit, to: 

<!DOCTYPE html>
<html>
    <head>
        <title>Aprendendo HTML e PHP</title>
    </head>

    <body>

        <?php $nome = "Mikaela"; ?>

        <p>Prazer, me chamo <?php echo $nome; ?>.</p>

    </body>
</html>

The phrase will be replaced by: "Prazer, me chamo Mikaela.".

Now do a little test and change the file extension to .html again and reload the page.

Did you notice the difference?

  

HTML is a markup language used in the construction of pages in the   Web. HTML documents can be interpreted by browsers .

     

PHP is a free interpreted language, originally used only   for the development of present and active applications on the   server. PHP scripts are interpreted on the server side .

Just do this, changing to php you make your server understand that that page have codes in php. If you try to, for example, run a php code with a * .html file, nothing will happen, it will only print a text on the screen with your code.

Changing the extension will only present a problem if the page needs to execute some instruction in PHP .

Example code page that will not have problem in both extensions: 

<h1>Hello World!</h1>

The "Hello World!" below will only be displayed if you have the extension in PHP : 

<h1><?php echo 'Hello World!'; ?></h1>
  

For the code PHP to run it must be on a Web server   prepared, like Apache for example.

To change is just to change the file extension, do not forget to put the .php file on an Apache server (you can use xampp, wampp ... for testing)

First you need to understand what is front-end and back-end, these questions should help:

So that's how it works, your machine / browser requests via HTTP a page on your site, PHP does not run on your machine, it's a script that generates an HTTP response and sends via download to its corresponding machine the request, something like these illustrations:

and

In other words, PHP processes a response that is HTML and depending on the server configuration the .php extension will not even exist, this is just a way the language uses to facilitate page creation.

The HTTP responses generated by your PHPs can be anything like: json, image, html, txt, etc.
