The cookie you are setting will not be visible to PHP until the next page request. The article you link to states this explicitly:

Of course, yes. This is not working correctly. In fact it’s working correctly from the second load on, but on the initial load of the page the $_COOKIE array does not has any anchor key inside. That’s because this part of the code is executed before the browser setup the cookie on the client.

There is a "workaround" presented in that article, but frankly: this sort of thing is rubbish and you should simply not put this information (only) in the query fragment if you want PHP to read it.

By article which you sent, you must do a redirect like:

<?php if (!$_COOKIE['anchor']){ ?>
<script language="javascript">
  var query = location.href.split('#');
  document.cookie = 'anchor=' + query[1];
  window.location.reload();
</script>
<?php } ?>

<?php
echo $_COOKIE['anchor'];
?>

Additionally, you seem to set wrong property in JS (it's .cookie, not .cookies):

document.cookie = 'anchor' + query[1];

You are setting a cookie that wont be passed to php until next reload. Am I wrong?

Client dynamics is the end of the chain.

Use this method to prevent errors:

<script> 
query=location.hash;
document.cookie= 'anchor'+query;
</script>

And of course in PHP, explode that puppy and get one of the values

$split = explode('/', $_COOKIE['anchor']);
print_r($split[1]); //to test it, use print_r. this line will print the value after the anchortag
