• Split PDF documents into separate pages using PHP (or possibly perl)

  - by Simon Stevens

  Can anybody point me towards a PHP library or script that would allow me to split a pdf consisting of multiple pages into separate files, each containing 1 page.

• Uploading PDF or .doc and security

  - by Kamo

  I have a script that lets the user upload text files (PDF or doc) to the server, then the plan is to convert them to raw text. But until the file is converted, it's in its raw format, which makes me worried about viruses and all kinds of nasty things. Any ideas what I need to do to minimize the risk of these unknown files. How to check if it's clean, or if it's even the format it claims to be and that it does not crash the server.
