I also used a tutorial on creating an international encyclopedia to add a call for wrapping all capital letters in SPAN tags, too. Wrapping things in those SPAN tags means that we can target them for specific formatting with CSS later. Now I have punctuation and capitalization in wrappings that I can style later. When turning each one on, I’ll make them larger and differently colored than the other text on the page.

I’ve put this script online and you’re welcome to it. Right now, only the file “text.txt” will be read. A few more things happened to it that make it more useful. There are limitations on all this, but the basic idea is there. If you do something cool with this, post back to let me know.

Your variable $text isn’t actually the text, it’s just a file handle. You need to use fread() to get the contents of the text file into a variable — the pnp.net docs are here:

I think the str_replace() call is okay; have you tested with just a bare string instead of the file contents?
