Why doesn't this php Hello World example run?

Question

<!DOCTYPE html>
<html>
<body>

<h1>My first PHP page</h1>

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

</body>
</html>

It only displays the html part, not the stuff in php tags? I'm just following the w3 tutorial.

Are you on windows?...if so, so you have something like wamp or xamp installed? — Hackerman, May 09 '17 at 22:00
not sure what that is, but i installed PHP yesterday.. is it different? — gchoi123x, May 09 '17 at 22:01
Do a view source and if you see the PHP code then you don't have a webserver / PHP installed correctly. — AbraCadaver, May 09 '17 at 22:01
you just installed the php interpreter...you also need a web server like apache, in order to run your code as a webpage... — Hackerman, May 09 '17 at 22:01
also, your file extension needs to be .php not .html, with the default setup — ATechGuy, May 09 '17 at 22:08

First thing first check that if your php is properly installed on your system if you are using windows or xampp then upload this file inside htdocs folder and try to run using localhot/index.php whatever your file name is.

And it will run properly. Let me know if you want more detail. If you are not sure how to run php on windows install xampp using this link:http://filehippo.com/download_xampp/ and once it is isntalled run apache and php and put your code inside htdocs folder. This should be easy

If you open this file locally as an .html file on your desktop or something it's not gonna work. You need to create a local server on your machine, install PHP and run on that.

I recommend https://www.mamp.info/en/ to get you started and where you can install PHP which instructions can be found here: http://php.net/manual/en/install.php
