How to close curly brackets in PHP [closed]

Question

Is it ok in PHP to close out curly bracket as follows?

<?php function myfunction() { ?>

   // stuff

<?php } ?>                 
<?php 

// more stuff

I just discovered that this breaks my Wordpress site, however if I close out the bracket like this:

<?php function myfunction() { ?>

   // stuff

<?php }                  

// more stuff

No problems are caused.

It's been a confusing afternoon! Any help much appreciated.

Answer 1

It is usually a bad idea to do:

?>
<?php

That adds output to the page, and prevents one from adding any headers, which may cause error if any code tries to add a header.

Whereas:

//nothing

Does not.
