Default strlen() and calculations

i set up a while in a function to pull some details from the database, however as part of the defined function i've set up a variable in order to get the length of a string and then subtract '4' from total. however upton checking this it seems that the variable
PHP Code:
            $galleryavatarextention strlen($galleryavatarinfo['bigimage'])-4
isn't being saved with or without the "-4" calculation on the end, basically it's a what am i doing wrong and am i doing this the right way type question?

I can't see anything wrong with that at all

What i would suggest is to put this before and see what it outputs, probably is the case that this has no value:

PHP Code:
echo $galleryavatarinfo['bigimage']; 
Also note vB has a built in function to get a file extension Use: file_extension. It's available to you on all pages
