PHP & .PDF & .ZIP ???

I need to automatically create a .PDF file from a *dynamically created* text file, then .ZIP that file up. Then *ultimately* have that file attached to an email and automatically sent. Can PHP do .PDF files? .ZIP Files? The caveat on the .PDF file is; it also needs to be locked (or password protected) like an EBOOK, where the end user will not be able to copy and paste out the contents -- I'm considering them not being able to print it also-- just the ability to view it on the screen. Can PHP help with all this? If so; if anyone has some sample code, that would be *very* helpful. Thanks. Jason
