Help with some php code

[elmcitizen]

i know it sounds funny but im setting up a companies forum and do to formatting in their industry, they would like all the post/thread subjects (the title of the post) to appear in capitol letters. Heres the big problem, some of the titles will be combinations of numbers and letters. Is there some php code that can be added to the newthread.php file to do this? Any help would be greatly appriciated.
