Can anyone see why this is working? (php function)

<?php
function hey(){
  return 'hey';
}
$space = hey();
echo $space;
?>

Hey Sheldon,

Looking at the code, I can't see why it wouldn't work.

You created a function that returns the string hey, then set the value of $space to whatever hey() is returning, then you're echoing out the value of $space, which at this point is the string 'hey'.

Is there something you felt shouldn't be working here?

It's working on this end, which could mean a few things:

*1. You're clicking on the php file, which will just produce a blank page in Chrome with the single line written out in full:

<?php function hey(){ return 'hey'; } $space = hey(); echo $space; ?>

If this is the case, then you may be simply opening the php file like you would an html file. PHP files don't work when you just open them, they need to be run on a server (local or hosted) running PHP, otherwise you'll see any html/css as normal, but the php code will show up as text.

*2. You're pathing to the file through a server, but the server doesn't have PHP enabled, or the PHP version isn't adequate to run the code.

If this is the case, look into getting PHP installed on the server and the code will run properly.

It's more than likely the first option though, so just upload your php file to a server and access it using a browser by navigating to the site the way a user would and you'll get the results you're looking for.

Try clearing your cache. Also, do other PHP sites work in your environment?

You can see the code works in this snapshot.

I agree with Daniel's answer. I would also like to add you can simplify your code like this:

<?php

function hey(){
  return 'hey';
}

echo hey();
?>
