I downloaded the Starkers nude theme recently and I have been redesigning my website with it. I was adding some functions to functions.php. and I noticed something: there is no closing tag at the end of the page for the PHP script. Is this an error OR does it not matter OR am I missing something? I don’t really know much about PHP, but this concerns me. Thank you in advance!
I’m pretty sure this isn’t an error. I’ve noticed it in the past and I’m fairly confident the functions file gets gets imported into the PHP of another file (or files) within WordPress. the closing tag is most likely included in that file. This allows WordPress to make sure key functions are always available. I’m not sure if that is actually happening but that’s what I’ve been lead to believe.
Actually, you can run into the same problem with the *opening* `< ?php` tag - extra whitespace (or a BOM inserted by your editor) can cause undesired output at the beginning of your script.
Unfortunately, there’s no way around that problem – just have to be careful.
