Can't show PHP file result in HTML

Question

Good afternoon,

So I met a problem, I can't display PHP file results in HTML.

As example I have php file named hi.php that contains code like this:

<?PHP
$hi="Hello!";
echo "$hi";
?>

And I have index.html that contains body like this:

<!DOCTYPE html>
<html>
<body>
<?php include "taskai.php" ?>
</body>
</html>

And I get a blank page... No results displayed from hi.php. I'm working on localhost, xampp. May this be the problem, or I have something wrong?

Good afternoon, Tomas. By default, HTML files doesn't load php commands: try to rename it in `index.php` — fusion3k, Mar 08 '16 at 14:57
Do you really get a *blank* page? What do you see when you view the page *source* in the web browser? — David, Mar 08 '16 at 14:57
as @fusion3k said, if your file ends with `.html` then any PHP in it will not work. However, the `hi.php` code should work by itself. What is your URL like when running `hi.php`? — CodeGodie, Mar 08 '16 at 14:59
_And I get a blank page_...If it's true then might be something wrong in `php.ini` — Domain, Mar 08 '16 at 15:02
why are you showing this `taskai.php` in your code? is that relevant? — CodeGodie, Mar 08 '16 at 15:03
@fusion3k, that worked well. But what should I do to echo result in HTML ? :) — , Mar 08 '16 at 15:03
you have to use [`include("taskai.php")`](http://php.net/manual/en/function.include.php) instead of [`show_source("taskai.php")`](http://php.net/manual/en/function.show-source.php) — fusion3k, Mar 08 '16 at 15:04
@david, in code I get my query as a comment `` @CodeGodie, the point is to show something from php file in HTML file :) I will use `include filename` because I need to display the result only — , Mar 08 '16 at 15:05
you need to instruct your system to treat `.html` files as PHP if you haven't already. If not, then give it the `.php` extension. You running this off a webserver or not? — Funk Forty Niner, Mar 08 '16 at 15:05
@TomasVilemaitis: Then clearly the PHP code isn't being evaluated. Which by default doesn't happen in `.html` files. You can rename it to `.php`, or you can configure your server to process `.html` files with PHP. (The former option is preferred, as the latter creates unnecessary overhead for HTML files.) — David, Mar 08 '16 at 15:06
and if local, you accessing as `http://localhost/file.xxx` or as `file:///file.xxx`? Two different animals here. — Funk Forty Niner, Mar 08 '16 at 15:06
Thank you for your time and answers guys! Solution is to change `index.html` to `index.php` or move to webserver :-)) Thank you once again! — , Mar 08 '16 at 15:10

Create a file index.php with that content:

<!DOCTYPE html>
<html>
<body>
<?php
$hi="Hello!";
echo "$hi";
?>
</body>
</html>

That should give you an idea of how things work.

There obviously are endless variants. For example you can also do this:

File index.php:

<?php
$hi="Hello!";

echo <<<EOT
<!DOCTYPE html>
<html>
<body>
{$hi}
</body>
</html>
EOT;

Two problems:

your HTML file should have the .php extension for it to understand PHP code change index.html to index.php

you are not using include to include the code onto your HTML

Do it this way:

index.php

<!DOCTYPE html>
<html>
    <body>
     <?php 
     include "taskai.php" 
     ?>
    </body>
</html>
